摘要
以沁水煤田成庄矿井奥陶系峰峰组地层为研究对象,通过对峰峰组和上马家沟组含水地层的地质特征、水化学特征及水力联系进行综合分析和对比,确定了峰峰组地层上部区段具有一定的隔水性能,研究了其隔水层厚度和地质分布规律,对矿井奥灰岩溶带压区的危险区的划分和圈定提供了科学的技术支撑,有效地增加了矿井安全区(可采区)的开采范围。
Taking the Ordovician Fengfeng Group of Chengzhuang Coal Mine, Qinshui coalfield as the research object, and by means of a comprehensive analysis and comparison of water-bearing strata geological characteristics, water chemical characteristics and hydraulic contact of the Fengfeng Group and the upper Majiagou Group, we determined the upper strata section Fengfeng Group have certain waterproof performance. Then we studied the thickness of water-resisting layer and the geological distribution, which provides scientifc and technical support mine the danger zone division of the ash karst pressure zone, and effectively increases the mine safety mining areas （panel）.
