Chen si lou coal mine lies in Yongcheng, Henan province. North of Longhai railway in mining area, East of Beijing-Shanghai Railway, Qing (Longshan ) -Fu (Yang) railway from the mine Southeast of about 20 km across, West Beijing-Kowloon Railway-Fu, the traffic is very convenient. It’s about5.11 km on the strike and 3.99 km on the dip,with the 18.27 km2 total horizontal area. The minable coal seam of this mine is only 2 with an average thickness of 6.45 m and an average dip of 7°. The proved reserves of this coal mine are 172.79 Mt and the minable reserves are 115.79 Mt, with a mine life of 59.4 a. Average thickness of overburden 200 m ;The geological condition of the mine is relatively simple. The normal mine inflow is 894 m3/h and the maximum mine inflow is 1200 m3/h. hardness coefficient of coal seam f=2. 5 ; Absolute for gas emission in coal mine 0.68 m 3 /min , Is a low gas mine; Dust explosive and less risk of spontaneous combustion 。Based on the geological condition of the mine, I bring forward four available project in technology. Programme a: shaft to 450m , single level develop, seam transport large Lane, rock track large lane ; programme second: shaft to 450m , single level develop, double rock large lane ; programme three: shaft to 450m , single level develop, seam transport Shang (Xia) mountain, rock track Shang (Xia) mountain ; programme four: shaft to 450m , single level develop, rock disk area Shang (Xia) mountain . Through technical and economic comparison to finalize the programme for best program. Main seam a level, horizontal elevation -480 m . Designed first mining district makes use of the method of panels in mining area, the length of working face is 178 m, which use top coal caving to exploit coal,fall to dispose worked out section. The working system is “three-eight”, with five working cycle every day. Advance of working cycle is 0.7 m, and quantity of 4888.49 ton coal is maked everyday.Main roadway makes use of belt conveyor to transport coal resource, and mine car to be assistant transport. Main shaft makes use of skip to transport coal resource, when subsidiary shaft makes use of cage to be assistant transport. In the prophase of mining the mine makes use of centralized ventilation method,when in the evening of mining the mine makes use of areas ventilation method. The project design is deep well Deformation mechanism and supporting technology in soft rock roadway.The translated academic paper is about Numeric Analysis of Hydraulic Fracturing Technique in Preventing Outburst and the Control Technique。Keywords:Chensilou coal mine; band mode; top coal caving; o Center juxtapose ventilation; soft rock roadway, hydraulic fracturing.目 录一般部分1 矿区概述与地质特征
