Description
Technical field
Patent of the present invention is related to a kind of measurement apparatus at core fracture inclination angle and the measuring method using this device.
Background technology
The mankind must use drilling technique to the research of subsurface formation and the prospecting of mineral resources, prospect including underground and drill
Drafting with stratigraphic section.The main purpose of probing is exactly the core extracting to be analyzed and records, in the future each
The development planting mankind's geological activity provides data refer and technical support.Due to core extract during with respect to original
Position have occurred that the rotation of unknown angle, therefore the tendency of the joint fracture comprising inside core cannot accurately obtain, from
And also can only take its angle with core drilling depth direction as the inclination angle of these fractures.Core fracture inclination angle and its developmental state are
Analysis rock mass completeness and the important parameter of rock-mass quality grade classification, are also to speculate that the internal fracture of rock mass exists and insertion
The Main Basiss of situation, therefore, the accurate statistics at core fracture inclination angle have important meaning for geological mapping.At present, to rock
The method that the measurement at core fracture inclination angle is mainly combined with protractor and ruler, that is, keep ruler with core drilling depth direction substantially
Always, record the angle between the fracture plane of fracture and ruler with protractor, because ruler is in unfixed state, therefore so
The resultant error obtaining is very big, is unfavorable for the true reflection of practical situation.This method overcomes current existing apparatus complex operation
Shortcoming, enormously simplify the comfort level of measurement, certainty of measurement also improve a lot.
Content of the invention
The technical problem to be solved in the present invention is to overcome in existing core fracture inclination angle measurement method due to device itself
The aspect defect such as structure and precision and quick, the convenient and accurate deficiency measuring core fracture inclination angle, thus provide a kind of steady
Determine reliable and efficient core fracture inclination angle measurement method and its special measurement device.
The technical solution adopted for the present invention to solve the technical problems is for solving above-mentioned technical problem, a kind of rock of the present invention
Core fracture dip measuring device includes：Have the end cap of a round mouth, end cap is bonded with guide rail and base, base is led positioned at two
Between rail, base is connected with another end plate with the other end of guide rail, and the upper surface of base is tangent with the round mouth on end cap；Two
The side plate that block is made of clear material, side plate bottom connection sliding block, slide block on guide rail slidably can have measurement on side plate
The arc-shaped scale of angle, the central point corresponding to two arc-shaped scale is connected with needle pivot, and needle pivot is cased with pointer, and
And this pointer can rotate freely around needle pivot.
Described pointer structure is one piece of square plate.
Measuring method of the present invention comprises the following steps：
(1) core is put on base along the circular hole of end cap, so that core fracture face is located near the graduated disc of side plate；
(2) adjust core position, make the free face of core fracture upward；
(3) adjust slide block, and rotating pointer, so that pointer is fitted tightly with core fracture face；
(4) position in arc-shaped scale for the side of reading pointer, reading is core fracture inclination angle.
Produced by the present invention, benefit is:The invention provides a kind of core fracture measurement of dip angle mode of efficient quick and
Its special purpose device, the material almost all of this device can be made up of transparent plastic or glass, and structure is simple, with low cost.This
The maximum advantage of invention is the shortcoming overcoming conventional core fracture dip measuring device complex operation, enormously simplify measurement stream
Journey, improves certainty of measurement, employs template pointer, can fit tightly with fracture, makes the degree of accuracy of core fracture measurement of dip angle
Significantly improve.
