张小楼煤矿1.5Mta新井设计.docx

1、摘 要本设计包括三个部分：一般部分、专题部分和翻译部分。一般部分针对张小楼矿井进行了井型为1.5Mt/a的新井设计。张小楼矿位于徐州市西北铜山县柳新镇和刘集镇境内。整个井田东西长约4.80km、南北宽约3.53km，井田面积16.54km2。开采深度为-280m-1250m。主采煤层为7煤和9煤，7煤煤厚6m，9煤煤厚3m，两煤层相距10m左右，为近距离煤层，煤层倾角变化较大，浅部平均20，深部平均5。矿井正常涌水量为76m3/h，最大涌水量为160m3/h；矿井相对瓦斯涌出量为3.35m3/t，属低瓦斯矿井。井田工业储量为205.39Mt，可采储量137Mt，矿井设计井型为1.5Mt/a，矿

2、井服务年限为65.24a。根据井田地质条件，设计采用立井两水平开拓方式，都为上下山准备方式，一水平位于-600m，上山垂高320m，下山垂高250m，二水平位于-1150m，上山垂高300m，下山垂高100m,。井田共分为7个采区和2个带区，轨道大巷和胶带机大巷岩石大巷，布置在9煤层底板岩层中。考虑到本矿井为低瓦斯矿井，矿井通风方式采用中央并列式通风。大巷采用胶带输送机运煤，辅助运输采用架线式电机车牵引固定箱式矿车。主井采用箕斗提煤，副井采用罐笼运料和升降人员。针对东一采区采用了采区联合准备方式，共划分3个区段，并进行了运煤、通风、运料、排矸、供电系统设计。针对7101工作面进行了采煤工艺设计

3、。该工作面煤层平均厚度为6.0m，平均倾角20，直接顶为泥岩，老顶为细砂岩。工作面采用长壁综采放顶煤采煤法。采用双滚筒采煤机割煤，往返一次割两刀。采用“四六制”工作制度，截深0.6m，每天六个循环，循环进尺3.6m，月推进度108m。专题部分题目为张小楼矿微震规律与冲击矿压关系研究，以张小楼矿95206工作面为背景，进行了详实的微震观测数据收集与处理，分析得到张小楼矿微震分布规律与冲击矿压关系，为张小楼矿进行防止冲击矿压提供了有力的技术支持。翻译部分题目为Mine gas drainage and outburst control in Australian underground coal
