Problems solved by technology

[0004] The purpose of the present invention is to provide a ventilation method for the roadway layout system used to solve the multiple disasters in the deep well working face in order to solve the above problems, which can not only solve the problems of gas accumulation in the upper corner of the working face and excessive temperature of the working face, but also improve the working environment. Moreover, it solves the difficult problem of Y-shaped ventilation roadway retention, changes the stress distribution of the roof by cutting the roof and relieves the pressure, and changes the passive support from filling to active pressure relief support, and solves the problem of large roadway when the adjacent working face digs along the trough along the gob. Deformation and difficult support problems. Furthermore, realize "one lane multi-purpose" in the floor roadway, cover the coal roadway excavation, and use it as the return air roadway of the working face to carry out exploration and discharge of water in the goaf in advance to reduce the impact of exploration and drainage on mining operations. Improve the safety and efficiency of water exploration and discharge

Abstract

The invention discloses a roadway arranging system ventilation method for avoiding deep well work face multielement disasters. A transportation roadway, a track roadway and a bottom plate air return roadway arranged below a work face are included, wherein the transportation roadway and the track roadway are arranged on the two sides of the work face. A top plate of the track roadway is provided with a plurality of ventilation holes. The upper portions of the ventilation holes communicate with the track roadway. The lower portions of the ventilation holes communicate with the bottom plate air return roadway. In the work face recovery process, the ventilation eyes between the end, back onto a goaf, of the track roadway and the work face are closed, the ventilation holes located in the goaf are opened, and the part, located in the goaf, of the track roadway communicates with the bottom plate air return roadway through the ventilation holes. Accordingly, the air return efficiency can be improved, gas accidents due to gas accumulation at an upper corner on the work face can be prevented, the temperature of the work face can be reduced as well, danger due to the too high gas temperatureis prevented, and the work environment of workers can be improved as well.

Description

technical field [0001] The invention belongs to the technical field of coal mining, and in particular relates to a ventilation method for a roadway layout system used to solve multiple disasters in deep well working faces. Background technique [0002] With the deepening of mine mining depth, the influence of natural geological conditions such as water, fire, gas, ground temperature, and ground pressure on mining has become increasingly prominent. In this regard, many scholars have carried out relevant research and achieved fruitful results, such as the masonry beam theory proposed by Academician Qian Minggao, the theory of transmitting rock beams proposed by Academician Song Zhenqi, the theory of constant resistance and large deformation support proposed by Academician He Manchao, and the theory of Yuan The theory of coal and gas co-mining proposed by Academician Liang, the achievement of these achievements provides theoretical support for the later related practical resear...
