清水营煤矿大倾角煤层赋存特征综合分析

The Synthesis Analysis Of Hosting Feature Of Coal Seam With Large Tilt Angle Of Qingshuiying Mine

全面了解复杂条件下大倾角煤层赋存特征是实现大采高开采安全开采的前提。清水营煤矿大采高工作面岩体节理与裂隙发育,富含水。基于现场地球物理勘探的基础上,完成了矿区工程地质特征的综合调查,分析了岩层岩性、构造、地震物理特征以及煤岩的物理/力学参数,为大采高安全开采提供了地质保障。

a universal understand of complicated conditions of hosting feature of coal seam with large tilt angle is the prerequisite to actualize the mining of large quantity, high quality and security. The large quantity high work surface of Qingshuiying Mine is with a developed rock joints and seams and rich in water. Based on the on-site geophysical exploration result, a synthesis survey of the features of engineering geolo- gy of the mining area was carried out to analyze the rock feature, structure, earthquake physical feature of the rock layer and physical and/or mechanical parameter of the coal layer for the geological safeguarding of the mining of large quantity, high quality and security.
