鲍店煤矿3.0 Mt/a新井设计 摘要 一般部分针对鲍店煤矿进行了井型为3.0 Mt/a的新井设计。鲍店煤矿位于山东兖州市邹城境内，井田走向长约7.2 km，倾向长约5.06 km，水平面积约35.1 km2。主采煤层为3（3上、3下）煤层，平均倾角8.9°，3煤平均厚度8.81 m。井田工业储量为399.267 Mt，可采储量276.470 Mt，整个矿井服务年限为70.89 a，一水平服务年限50.57 a。矿井正常涌水量为100 m3/h，最大涌水量为300 m3/h；矿井相对瓦斯涌出量为1.5 m3/t，属瓦斯矿井。根据井田地质条件，设计采用立井两水平采带区式结合开拓，一水平标高-375 m，二水平标高-500 m，在井田内划分四个采区，五个带区。轨道大巷、运输大巷皆为岩石大巷，布置在3煤层底板岩层中。本矿井前期采用中央并列式通风，后期采用中央分列式（边界式）通风。 针对北一带区采用了带区准备方式，共划分26个分带工作面，并进行了运煤、通风、运料、排矸、供电系统设计。 针对3102工作面进行了采煤工艺设计。该工作面煤层平均厚度为8.5 m，平均倾角6.2°。工作面采用放顶煤综合机械化采煤法。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0.8 m，每个循环进尺1.6 m，每天三个循环，月推进度132 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12 t箕斗提煤，副井采用一对1.5 t矿车双层四车窄罐笼和一个带平衡锤的1.5 t矿车双层四车宽罐笼运料和升降人员。 专题部分题目为《深部高温矿井热害治理技术研究》，详细阐述了国内外对于矿井热害理论、技术的研究现状，并针对现有理论不足，对井巷喷注隔热材料新型井下主动降温方法作了初步实验探究。 翻译部分题目为《Modeli
