Abstract
The invention discloses a min development method, and belongs to the field of mine roadway excavation technology. The method comprises the steps of developing an improved well transportation footrill and an improved well air-return footrill from the ground; then excavating an auxiliary cutting hole and a part of a cutting hole to form a ventilation circuit and a transportation system, preparing the cutting hole in advance; tunneling a work plane transportation roadway and a work plane rail roadway from the improved well transportation footrill and the improved well air-return footrill; tunneling the work plane transportation roadway and the work plane rail roadway after cross-measure cutting coal, wherein the work plane transportation roadway and the work plane rail roadway can be tunneled from two ends simultaneously so as to accelerate formation of a coal face circuit; and finally cutting through the cutting hole, the work plane transportation roadway and the work plane rail roadway. The mine development method can carry out recovery rapidly and realize production in advance.
Description
Technical field
The present invention relates to a kind of mine development method, belong to extraction technique field, tunnel, ore deposit.
Background technology
Coal is one of important energy source of China, plays a part very important to the development of the national economy and development.At present in coal mine roadway developing, the mine laneway development method adopted is (for rice square-bottomed bamboo basket ore deposit, as Fig. 2), from ground driving transport, track and return air three inclined shafts, then dig haulage cross-cut, track crossdrift and track gallery, windstone gate respectively, after exposed coal three corresponding positions of inclined shaft, driving face haulage way and track gallery are to cutting eye place again, finally throughly cut eye, form coal-face, just can mine.But this traditional method is only after three corresponding positions of inclined shaft excavate haulage cross-cut, track crossdrift and track gallery, windstone gate, ability digging work face haulage way and track gallery, and work plane haulage way and track heading excessively slow, cause production time long for long i.e. investment cycle; And the resistance of ventilation and draining is large when operation, power supply and the distance supplied water, mining equiment is transported to the problems such as the time length of coal-face, causes the production efficiency in colliery and the reliability reduction of mine.
As from the foregoing, iff employing conventional well development method, then cause production time long, be therefore necessary to improve existing mine development method, realize going into operation in advance, to produce larger economic benefit.
Summary of the invention
For above-mentioned prior art Problems existing, the invention provides a kind of mine development method, there is the fireballing effect of developing, improve production efficiency and the reliability of mine.
To achieve these goals, the technical solution used in the present invention is: a kind of mine development method, digs haulage cross-cut, track crossdrift and track gallery, windstone gate respectively from return air inclined shaft, track inclined shaft and the corresponding position of transport inclined shaft; After exposed coal, driving face haulage way and work plane track gallery;
(1) from ground opening-up measure well haulage tunnel and service shaft return air footrill;
(2) excavate the auxiliary part of cutting eye and cutting eye, form ventilation circuit and transportation system;
(3) from service shaft haulage tunnel and service shaft return air drifting work plane haulage way and work plane track gallery;
(4) from driving face haulage way while of two ends, coal seam and work plane track gallery;
(5) through cut eye, work plane haulage way and work plane track gallery after, carry out back production.
Auxiliary cut eye and excavate when distance cuts eye 20 meters.
The invention has the beneficial effects as follows: (1) the inventive method also can not dig three corresponding positions of inclined shaft haulage cross-cut, track crossdrift and track gallery, windstone gate time, just can from service shaft haulage tunnel and service shaft return air footrill digging work face haulage way and track gallery; After excavating haulage cross-cut, track crossdrift and track gallery, windstone gate, two ends just can be tunneled simultaneously, this will greatly improve the driving speed of transport face gallery and track gallery, through work plane haulage way and track gallery can be shifted to an earlier date, realize going into operation in advance, going into operation for the former progress in rice square-bottomed bamboo basket colliery is 2 ~ 2.5 years, adopts development method of the present invention to realize just can going into operation for 1 ~ 1.5 year, be advanced by operation in 1 ~ 1.5 year, create huge economic benefit and social benefit.
(2) the service shaft haulage tunnel newly opened up and service shaft return air footrill are before operation, can be used for ventilating, assisting fortune coal, pedestrian, haulage device, auxiliary material transport, shorten equipment conveying and set-up time, travel time, alleviate the transport pressure of transport inclined shaft and track inclined shaft, can enhance productivity and namely add the economic benefit in colliery with mine reliability of operation.
(3) the service shaft haulage tunnel newly opened up and service shaft return air footrill can provide same function for the next one face of adopting, and preparing, realizing recycling for going into operation in advance; About there are 5 to adopt face for rice square-bottomed bamboo basket colliery, go into operation in advance, huge economic benefit can not only be produced, also save cost for 5 times that just can realize the face of adopting.

Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in Figure 1, the present invention is first from ground developing return air inclined shaft 1, track inclined shaft 2 and transport inclined shaft 3, haulage cross-cut 7, track crossdrift 5 and track gallery 6, windstone gate 4 is dug respectively from the corresponding position of return air inclined shaft 1, track inclined shaft 2 and transport inclined shaft 3, after exposed coal, driving face haulage way 11 and work plane track gallery 9; Excavate service shaft haulage tunnel 14 and service shaft return air footrill 15 simultaneously, then excavate the auxiliary part of cutting eye 13 and cutting eye 12, form ventilation circuit and transportation system, prepare out in advance to cut eye 12; Now from service shaft haulage tunnel 14 and service shaft return air footrill 15 driving face haulage way 11 and work plane track gallery 9, so just can two ends simultaneously driving face haulage way 11 and work plane track gallery 9, accelerate the formation of adopting loop, face, finally through eye 12, work plane haulage way 11 and the work plane track gallery 9 cut just can carry out back production, realizes going into operation in advance.
Service shaft haulage tunnel 14 and service shaft return air footrill 15, before operation, can be used for ventilating, assisting fortune coal, pedestrian, haulage device, auxiliary material transport.Auxiliary cut the 20m place that eye 13 cuts eye 12 in distance and excavate.
Service shaft haulage tunnel 14 and service shaft return air footrill 15 can be gone into operation in advance for next one face of adopting and be provided same function.
Fig. 2 is the mining face arrangement figure of conventional well roadway opening, owing to tunneling transport, track and return air three inclined shafts from ground, then haulage cross-cut, track crossdrift and track gallery, windstone gate is dug respectively three corresponding positions of inclined shaft, after exposed coal, driving face haulage way and track gallery are to cutting eye place again, finally throughly cut eye, form coal-face, mine.But this traditional method is only after three corresponding positions of inclined shaft excavate haulage cross-cut, track crossdrift and track gallery, windstone gate, ability digging work face haulage way and track gallery, and work plane haulage way and track heading excessively slow, cause production time long for long i.e. investment cycle; And the resistance of ventilation and draining is large when operation, power supply and the distance supplied water, mining equiment is transported to the problems such as the time length of coal-face, causes the production efficiency in colliery and the reliability reduction of mine.
