Speedy tunneling method for gas drainage roadway

Abstract

The invention discloses a speedy tunneling method for a gas drainage roadway. The speedy tunneling method comprises the following steps: tunneling a return air inclined shaft, a rail inclined shaft and a transportation inclined shaft from the ground, and then respectively digging an return air stone door, a rail stone door, a rail gate way and a transporting stone door in positions respectively corresponding to the return air inclined shaft, the rail inclined shaft and the transportation inclined shaft; exploiting a measure shaft haulage tunnel and a measure well return air haulage tunnel, and then digging auxiliary cutting holes, a part of cutting holes, and a measure shaft gas lane so as to form a ventilation circuit and a transportation system; at the moment, the measure shaft haulage tunnel digs a base plate gas lane through the measure shaft gas lane; simultaneously digging into the base plate gas lane from the rail inclined shaft through the rail gate way, namely, the two ends simultaneously dig the base plate gas lane until the base plate gas lane is through, and the base plate gas lane and the measure shaft haulage tunnel form a gas drainage roadway circuit. The speedy tunneling method can be used for digging the gas drainage roadway quickly, realizes mine safe production, extraction and production, and produces more economic and social benefits.

Description

technical field [0001] The invention relates to an excavation method for a mine gas drainage roadway, in particular to a rapid excavation method for a gas drainage roadway. Background technique [0002] my country is a large coal-producing country, and coal is the main energy source for my country's economic development; but at the same time, my country is also one of the countries with the most serious gas disasters in the world, and more than half of the coal mines are high-gas outburst mines, so gas disasters seriously threaten the safe production of coal mines . [0003] At present, the gas drainage technology in coal mines (taking Miluo Coal Mine as an example) is to excavate three inclined shafts for transportation, track and return air from the ground, and then excavate the track roadway at the corresponding position of the track inclined shaft, and then excavate the floor gas roadway or Roof gas lane, that is, to excavate a gas drainage circuit, and the gas can be dr...

Problems solved by technology

However, this excavation method leads to a slow process of excavating the gas lane, which generally takes 1-2 years, and only after the gas lane is completely excavated, can the track level road and the transportation level road be excavated, and finally the mining face is formed for coal mining. Greatly delay the mine's commissioning schedule, and ultimately affect the mine's profitability

[0004] It can be seen from the above that if the conventional mine development method of gas drainage is used, the excavation of the gas drainage roadway will be delayed, resulting in the lag of the excavation of the track level roadway and the transportation level wayway, and the mine will be delayed. Improve the mine development method, and realize the production in advance to generate greater economic and social benefits under the premise of safe production in the mine
