|
Abstract:
以顾北煤矿为研究对象，详细分析了顾北煤矿浅埋煤层覆岩风化带的工程地质特征与含隔水性能。通过对顾北煤矿研究区岩石进行X射线衍射、单轴压缩、巴西劈裂岩石力学实验等测试，系统研究了浅埋煤层覆岩风化带岩性及矿物成分特征和物理力学性质，利用surfer软件绘制厚度等值线图并分析其分布规律，研究风化带的含隔水性能，为松散含水层下安全开采水文工程地质问题及成灾机理等提供可靠的基础资料。
Taking Gubei Coal Mine as the research object, the engineering geological characteristics and water-retaining properties of weathering zone of overlying rock in shallow coal seam of Gubei Coal Mine are analyzed in detail. Through X-ray diffraction, uniaxial compression and Brazilian split rock mechanics experiments on the rocks in the research area of Gubei Coal Mine, the lithology, mineral composition characteristics and physical and mechanical properties of the weathering zone of overburden rocks in shallow coal seam are systematically studied. Surfer software is used to draw thickness isoline map and analyze its distribution law to study the water-containing properties of the weathering zone. It provides reliable basic data for hydrologic engineering geological problems and disaster mechanism of safe mining under loose aquifers.
