1、摘 要一般部分针对钱营孜矿井进行了井型为1.5Mt/a的新井设计。钱营孜矿井位于安徽省宿州市境内，井田走向长约7.0km，倾向长约5.3km，面积约37.1km2。主采煤层为32煤层，平均倾角1215，平均厚度2.89m。井田工业储量为216.6Mt，可采储量161.0Mt，矿井服务年限为71.6a。矿井正常涌水量为434m3/h，最大涌水量为885m3/h。矿井相对瓦斯涌出量为2.5m3/t，绝对瓦斯量10 m3/min，属低瓦斯矿井。根据井田地质条件，设计采用立井两水平开拓方式，主井暗斜井延深，副井、中央风井立井直接延深，轨道大巷、胶带机运输大巷和回风大巷皆为岩石大巷，布置在32煤层底板岩
2、层中。一水平标高-480 m，二水平标高-700 m。西二采区采用了采区准备方式，共划分为五个工作面，并进行了运煤、通风、运料、排矸、供电系统设计。针对32202工作面进行了采煤工艺设计。该工作面煤层平均厚度为2.89 m，平均倾角12.6，直接顶为的砂质泥岩，老顶为细砂岩。工作面采用长壁综采一次采全高采煤法。采用双滚筒采煤机割煤，往返一次割两刀。采用“三八制”工作制度，截深0.8 m，每天八个循环，循环进尺6.4m，月推进度192 m。大巷采用胶带输送机运煤，辅助运输采用蓄电池式电机车牵引固定箱式矿车。主井采用两套带平衡锤的16 t箕斗提煤，副井采用一对1.0 t矿车双层四车窄罐笼和一个带平
3、衡锤的1.0 t矿车双层四车宽罐笼运料和升降人员。专题部分题目是综采工作面矸石充填技术初探, 通过分析上覆岩层的破断规律，定义了柔性关键层，分析出了柔性关键层对关键层复合破断和矿压显现的影响。翻译部分题目是Recent Developments and Practices to Control Fire in Undergound Coal Mines。关键词：钱营孜矿；立井开拓；暗斜井；采区布置；中央并列式；柔性关键层ABSTRACTThe general design is about a 1.50 Mt/a new underground mine design of Qianyingz
4、i coal mine. Qianyingzi coal mine is located in Suzhou, Anhui province. Its about 7.0 km on the strike and 5.3 km on the dip, with the 37.1 km2 total horizontal area. The minable coal seam is 32with an average thickness of 2.89 m and an average dip of 1215. The proved reserves of this coal mine are
5、216.6 Mt and the minable reserves are 161.0 Mt, with a mine life of 71.6 a. The normal mine inflow is 434 m3/h and the maximum mine inflow is 885 m3/h. The mine gas emission rate is 2.5 m3/t and 10 m3/min which can be recognized as low gas mine. Based on the geological condition of the mine, this de

7、oor rock of 32 coal seam. The first level is at -480 m. The second level is at -700 m.The design applies district preparation against the first district of West Two which divided into five longwall faces totally, and conducted coal conveyance, ventilation, gangue conveyance and electricity designing
8、.The design conducted coal mining technology design against the 32202 face. The coal seam average thickness of this working face is 2.89 m and the average dip is 12.6, the immediate roof is mud stone and the main roof is sand stone. The working face applies fully mechanized longwall full-height coal
