Before describing the construction method of the transparent geological model of the coal mine provided by the application, the background content related to the application is first described.

The construction method and device for the transparent coal mine geological model and the computer-readable storage medium can be applied to processing equipment, are used for constructing the transparent coal mine geological model with the functions of real-time calling, displaying, storing and curve analyzing and a matched geomechanical information three-dimensional visualization system, and are beneficial to accurate prevention and treatment of deep mining disasters in practical application.

According to the method for constructing the transparent geological model of the coal mine, the execution main body can be a construction device of the transparent geological model of the coal mine, or different types of processing Equipment such as a server, a physical host or User Equipment (UE) which integrates the construction device of the transparent geological model of the coal mine. The device for constructing the transparent geological model of the coal mine can be realized in a hardware or software mode, the UE can be a terminal device such as a smart phone, a tablet computer, a notebook computer, a desktop computer or a Personal Digital Assistant (PDA), and the processing device can be set in a device cluster mode.

As a specific implementation manner, the processing device may specifically be a desktop host, a notebook, and other common specific hardware devices that are convenient for field deployment in a coal mine engineering field, or the processing device may provide remote data guidance for a coal mine engineering field in a local laboratory environment by means of a cloud server.

Obviously, the specific device form of the processing device may be adjusted according to the specific application requirements in practical application, and the application is not limited herein.

The construction method of the transparent geological model of the coal mine provided by the application is started to be described below.

First, referring to fig. 1, fig. 1 shows a schematic flow chart of the method for constructing a transparent geological model of a coal mine according to the present application, and the method for constructing a transparent geological model of a coal mine according to the present application may specifically include the following steps S101 to S103:

step S101, processing equipment builds a database of a target coal mine area, wherein the database comprises a surrounding rock mechanical parameter database and a ground stress database;

it will be appreciated that the data processing referred to herein is developed with a determined coal mine area as the target object, and that the coal mine area currently identified as the target object may be referred to as the target coal mine area.

The coal mine area can be understood as an area related to coal mine engineering, and is related to mining work of coal mine resources.

The database related to step S101 may be understood as the formation of parameters of the target coal mine area in the aspect of mechanics, and the formation of parameters may be directly embodied in the form of a parameter set, or may be obtained by filling related parameters in a preset database structure.

Specifically, the method mainly comprises two aspects of a database of a target coal mine area, namely a surrounding rock mechanical parameter database and a ground stress database.

For the surrounding rock mechanics database, it is easy to understand that the database represents the surrounding rock mechanics aspect of the target coal mine area, and similarly, the geostress database is the database representing the geostress aspect of the target coal mine area.

It can be understood that, for the construction of the relevant model of the target coal mine area, the application considers that the mechanical characteristics including the two aspects of the surrounding rock mechanics and the ground stress can be considered, so that a good data basis can be provided for the accurate construction of the subsequent transparent geological model of the coal mine.

In the deep mining process, the ground stress is only an appearance and is a fundamental driving factor, so that the refined ground stress parameter data can be obtained, and the great contribution can be brought to the high fineness of the subsequent transparent geological model of the coal mine.

As a practical implementation manner, in the process of constructing the surrounding rock mechanics database in the database here, the following implementation manners are specifically adopted:

the processing equipment carries out inverse analysis processing and field collection processing by aiming at indoor test processing and a support vector regression optimization algorithm which are developed by a target coal mine area to obtain different parameters of the target coal mine area so as to form a surrounding rock mechanical parameter database, wherein the different parameters of the target coal mine area specifically comprise parameters such as the number, lithology, three-dimensional coordinates, compressive strength, tensile strength, elastic modulus, poisson's ratio, porosity, volume weight, softening coefficient and the like of different rock strata.

It is understood that the related measurement devices required for data processing in the present application, such as those listed herein for laboratory test processing and field collection processing, can be included in the processing device, or can be in the form of external devices to provide a tool basis for the processing device, and can be adjusted according to actual conditions.

In addition, for the mechanical parameters of the surrounding rock, besides the number, lithology, three-dimensional coordinates, compressive strength, tensile strength, elastic modulus, poisson's ratio, porosity, volume weight and softening coefficient of different rock strata listed here, other parameters can be involved in specific operations and can be adjusted according to actual conditions.

As another practical implementation, in the process of constructing the ground stress database in the database herein, the following may be specifically implemented:

the processing equipment acquires mining area ground stress measuring point data obtained by field ground stress test;

and the processing equipment performs inversion analysis by adopting a support vector regression algorithm on the basis of the data of the mine area ground stress measuring points to obtain the mine area ground stress distribution data so as to form a ground stress database.

It can be understood that, in terms of ground stress, the present application can analyze the overall ground stress distribution condition of the target coal mine area by an inversion analysis method based on actual measuring points (i.e. the ground stress measuring point data of the mine area, which can be obtained by manually measuring the field by a stress relieving method and a rheological stress recovery method), so as to obtain a ground stress database of the target coal mine area.

As a specific implementation manner, in the inversion analysis based on the support vector regression algorithm, the practical application may specifically include the following processing contents:

It can be seen that in the embodiment of the present application, a secondary stress calculation method is adopted to analyze the ground stress distribution, so as to improve the analysis accuracy of the ground stress, and 1500 to 2000 preset number of data points are selected from the analysis result, i.e., the stress state of the whole model and fault, to be output as the result of the final inversion analysis.

S102, processing equipment builds a three-dimensional model of a target coal mine area, wherein the three-dimensional model comprises a three-dimensional drilling model and a three-dimensional geological model;

on the other hand of constructing the database of the target coal mine area, the method also needs to construct a three-dimensional model of the target coal mine area.

It should be understood that, for the construction process of the database and the three-dimensional model, there is no particular limitation between the two, and the database may be constructed first and then the three-dimensional model, or the three-dimensional model may be constructed first and then the database, or both may be constructed at the same time, which may be adjusted according to the actual situation, and the present application is not limited specifically herein.

The three-dimensional model referred to in step S102 may be, in a popular way, understood as the formation of parameters of the target coal mine area in terms of a three-dimensional structure, and the parameters may be directly embodied in the form of a parameter set, or obtained by filling relevant parameters into a preset database structure.

Specifically, for a three-dimensional model of a target coal mine area, the method mainly comprises two aspects, namely a three-dimensional drilling model and a three-dimensional geological model.

For the three-dimensional drilling model, it is easy to understand that the three-dimensional drilling model represents a three-dimensional structure model determined by the target coal mine area based on the drilling data, and similarly, the three-dimensional geological model represents a three-dimensional structure model determined by the target coal mine area based on the geological data.

It can be understood that for the construction of the coal mine transparent geological model of the target coal mine area, the application considers that the three-dimensional structural characteristics of the three-dimensional drilling model and the three-dimensional geological model can be considered, so that a good data basis can be provided for the accurate construction of the subsequent coal mine transparent geological model.

As another practical implementation, in the process of constructing the three-dimensional drilling hole model in the three-dimensional model, the following implementation may be specifically implemented:

based on the drilling histogram, establishing a drilling data structure mode and a standard stratum structure model of a stratum to be constructed in the whole region;

on the basis of a drilling data structure mode and a standard stratum structure model of a stratum required to be constructed in the whole area, SECTION software secondarily developed by a Geographic Information System (GIS) platform is adopted to establish a three-dimensional drilling digital model.

It can be understood that the drilling histogram is an engineering geological map compiled for describing the stratigraphy, thickness, lithology, structural configuration and contact relation, underground water sampling and testing, drilling structure and drilling conditions of a drilling hole penetrating through a rock stratum, and the engineering geological map is used as input data for data processing of a subsequent drilling data structure mode, a standard stratum structure model of a stratum required to be constructed in the whole region and SECTION software secondarily developed by a GIS platform.

As another practical implementation, in the process of constructing the three-dimensional geological model in the three-dimensional model, the following may be specifically implemented:

establishing a three-dimensional geological triangular grid model of each stratum of a mining area based on a GIS platform, a drilling interpolation fitting algorithm and an interface constraint algorithm;

three-dimensional geological modeling software based on QuantyView (the existing three-dimensional visual platform) is combined with three-dimensional geological triangular grid models of all stratums to construct three-dimensional geological models of all the stratums.

The data source processed based on the algorithm or the tool can be understood as being selected according to the collection and arrangement of the drilling data of the mining area in the previous period and the plane distribution form of the mining area.

Wherein, this application can be to the arrangement of categorised to drilling data, establishes drilling location table, drilling lithology table and drilling orbit table to establish drilling database based on the three and supply data to use.

As another example, the effective boreholes may be analyzed and processed based on the geological data collected earlier, and the boreholes may be normalized based on the determined standard strata of the local area, each borehole having a demarcation point for the standard strata, and the stratum with a missing borehole being processed to a thickness of 0.

It can be understood that in the embodiment, a two-layer modeling mechanism is adopted, a three-dimensional geological triangular grid model of each stratum of the target coal mine area is constructed through a GIS platform, a drilling interpolation fitting algorithm and an interface constraint algorithm, and then joint processing is performed through three-dimensional geological modeling software of QuantyView, so that a three-dimensional geological model representing the whole and all the stratums of the target coal mine area is obtained.

And S103, constructing a coal mine transparent geological model of the target coal mine area and a geomechanical information three-dimensional visualization system matched with the coal mine transparent geological model by the processing equipment on the basis of the database and the three-dimensional model.

It can be understood that after the preparation work of the database and the preparation work of the three-dimensional model are completed, the coal mine transparent geological model of the target coal mine area and the geomechanical information three-dimensional visualization system matched with the coal mine transparent geological model can be constructed on the basis of the database and the three-dimensional model.

The coal mine transparent geological model is processed from the perspective of a structural model, the coal mine transparent geological model takes transparency as a target and represents mechanical characteristics and three-dimensional structural characteristics of a target coal mine area with good visualization conditions, the geomechanical information three-dimensional visualization system can be a query system which is constructed for query service provided for a user on the basis of the condition matched with the coal mine transparent geological model, the query service can specifically query the mechanical characteristics and the three-dimensional structural characteristics in a specific position range of the target coal mine area, and in addition, query of other aspects of the target coal mine area and even data of an application system can be provided.

It can be understood that, in the prior art, the existing research mainly aims at establishing a mathematical and finite element model for specific working conditions, and then obtains a regional stress field through simulation, calculation and analysis, and the inversion result of the regional stress field is not strong in universality and difficult to be used by field engineering technicians due to the adoption of the method.

As another specific implementation manner, in the construction process of the geomechanical information three-dimensional visualization system matched with the coal mine transparent geological model and the coal mine transparent geological model in the target coal mine area, the following contents may be specifically included:

It can be seen that, in the specific processing process of the embodiment of the application, the spatial data management technology, the object-relationship data management technology, the attribute data management technology and the Web3D developer are integrated, and how to construct the coal mine transparent geological model which is visualized and convenient to query and the geomechanical information three-dimensional visualization system matched with the coal mine transparent geological model.

As another practical implementation manner, the transparent coal mine geological model is provided with a system setting menu on a main interface, and the system setting menu on the main interface provides display scenes including the model, the model transparency, the earth surface transparency and the underground mode and adjustment settings of parameters of the display scenes;

furthermore, because the three-dimensional geological model is below the surface remote sensing image from the spatial position, under the normal condition, the three-dimensional geological model cannot be seen from the ground viewing angle, in order to see both the surface and the three-dimensional geological model, the transparency of the surface remote sensing image can be adjusted through a sliding rod in the scene setting of the transparent geological model of the coal mine, or the underground mode is opened to browse from the downward and upward viewing angles in an internal mode, so that the surface image and the underground three-dimensional geological model can be seen simultaneously, and particularly, a scene schematic diagram of the surface image and the underground three-dimensional geological model can be seen simultaneously by referring to the application shown in fig. 2.

Further, as another specific implementation manner, the transparent coal mine geological model can also have a line drawing and sectioning analysis function, and the function mainly comprises the following steps:

and (4) arbitrarily drawing a section line on the remote sensing image of the earth surface as required, and automatically drawing a section diagram corresponding to the section line by using the information of the three-dimensional geological model.

For the line drawing sectioning analysis, it can be understood that, as a characteristic function of the present application, when the function is used, a user only needs to draw a section line on the surface remote sensing image as required, and the system can automatically draw a section view corresponding to the section line by using the information of the three-dimensional geological model.

As another example, in the geological model drawing and cutting result graph, a mouse can be moved to any stratum, so that the stratum can be highlighted and the thicknesses of all the stratums at the current position can be displayed; the vertical sliding rod on the right side of the geological profile analysis diagram is dragged, and the display range of the geological profile analysis diagram can be dynamically adjusted, so that the local query function of the geological profile analysis diagram is realized.

It can be understood that the cutting can be freely performed by the user according to the needs of the user, so that refined data of the stratum, the roadway and the like can be acquired.

Further, as another specific implementation manner, the transparent coal mine geological model can also have a space query function of a full-mining-area roadway and a main fault, and the function mainly comprises the following steps:

through a menu bar three-dimensional model and model setting, only displaying main roadways (faults) of a mining area in an area after clicking a checking roadway (fault) model;

as another example, the geological model, the fault model and the roadway model can be defaulted to be in a display state, and the transparency degree of the model is 0%, namely, the non-transparent state, under the condition, the model display switching button can be clicked to control the display and the hiding of the model, and the transparency degree slider can be dragged to adjust the transparency degree of the model, so that the more flexible and visual space query effect is realized, and various different query requirements are met.

It is appreciated that embodiments herein can refine the query object, thus providing a more refined spatial query effect.

Further, as another specific implementation manner, the transparent coal mine geological model may further have a model attribute pickup function, which mainly includes:

under the condition of model display, clicking an attribute pickup submenu under a three-dimensional model menu, and clicking a geological model to finish the query of information such as lithology of a stratum, related mechanical parameters and the like; clicking the roadway model to obtain information such as the name of the roadway, three-dimensional coordinates of a starting point and a finishing point and the like; and clicking the fault model to obtain information such as fault name, thickness, space coordinates and the like from a window popped up from the upper right corner.

Under the spatial query setting, the information of different rock stratums in the three-dimensional geological model and the rock mechanical parameter information corresponding to the information can be checked.

It is to be appreciated that embodiments herein can automatically display model attributes that can be queried, which can prompt users for more refined query services in an active alert manner.
