1、第9页摘 要一般部分针对岱庄煤矿进行了井型为1.2 Mt/a的新井设计。岱庄煤矿位于山东省济宁市境内。煤层厚度平均2.9m，平均倾角都为3。井田工业储量为160.23 Mt，可采储量124.5 Mt，矿井服务年限为79.8a。矿井正常涌水量为378 m3/h，最大涌水量为400 m3/h；矿井属低瓦斯矿井。根据井田地质条件，设计采用立井单水平开拓方式，带区式布置方式，共划分为5个带区，水平标高-500 m。轨道大巷、胶带机大巷皆为岩石大巷，布置在煤层底板岩层中。一带区共划分12个分带工作面，并进行了运煤、通风、运料、排矸、供电系统设计。带区服务年限16年。对工作面进行了采煤工艺设计。该工作面煤
2、层平均厚度为2.9m，平均倾角3，直接顶为粘土砂岩，老顶为细砂岩。工作面采用长壁综采一次采全高的采煤方法。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，每天六个循环，循环进尺4.8 m，月推进度144 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1.5 t矿车双层四车宽罐笼运料和升降人员。专题部分题目是厚煤层分层开采及巷道合理位置确定模拟分析，经过查阅大量资料和结合实验所得结论，认为本文所提出的确定厚煤层下分层煤层回采巷道合理位置的方法是可行的，研究结果对类似条件下巷道合理布置具有一
