Abstract
    The design is the exploitation of MaiDiZhang 02,6,8 # coal mine, coal seam thickness was m, , , seam pitch was 60 m, 40m. According to data mine the external investigation of the mine field for the high-gas coal mine, the coal gas emission in an average of / t, the next group of coal to / t. Seam of both the risk of explosion. Grade coal to natural tendency not spontaneous combustion. According to mine discharge forecast, the normal discharge of mine for 1255m3/ d, Chung's largest water at 1600 m3/ d
The Coal Mine in Qingxu county, 10 km NATO, which has Gujiao Qingxu to the same highway. Qingxu county from the Taiyuan city about 40 km, which has the same 307 National Road. Although the mine in more complex terrain, but between the village and village roads are linked to simple, can use trucks. Therefore, the location of Industry Square in the vicinity of Chen Jia Ping, a shaft development, Lord, vice shaft ventilation shaft and the section were m2, m2, m2. Develop a programme for the Chen-ping from the vicinity of the north east is necessary to develop the transport, rail, air return roadway to the north mine the border and then west from Chen Jia Ping pioneering South transport, rail tunnel, and then north tunneling West transport, track , To the wind tunnel. Option 2 is in the south of Chen Jia Ping tunneling transport, rail and air return roadway, and then in mine excavation west of the West transport, rail, air return roadway to the northern border. Option 1, two are located in the industrial plaza near Chen Jia Ping. According to comparison can be regarded as pioneering works of the same, but the technical programme in the reverse transport, and face the direction of advancing too long, equipment requirements, so I chose to develop a programme. Develop a p
