摘　　要：在对区域和良庄井田水文地质特征分析的基础上,探讨了开采煤层底板徐家庄灰岩和奥陶系灰岩水文地质特征,得出了徐家庄灰岩和奥陶系灰岩岩溶裂隙的发育及其富水性受断裂构造控制的结论。通过对煤层底板岩层的组合特征、厚度变化及含水层水位分布规律的研究,利用突水系数法评价了井田内后组煤开采的安全性,得出了徐灰水、奥灰水对11煤的开采影响不大,对13煤的开采有一定的影响,对15煤的开采威胁大的结论。Based on the analysis of extraction area and mine hydro-geological features of Liangzhuang Mine, the paper discusses the hydro-geological features of Xujiazhuang limestone and Ordovician limestone in coal floor. The con- clusion is that the development of karst crack and the water-bearing properties in Xujiazhuang limestone and Ordovi- cian limestone are controlled by fault structure. After analyzing the strata combination and diversification regularity of coal floor, and water level distribution of Xujiazhuang limestone and Ordovician limestone, the evaluation of safe mining for lower group coal is made by the water inrush coefficient method, and the conclusion is that there is a little effect of water from Xujiazhuang limestone and Ordovician limestone on the mining of 11^th coal. certain effect on 13^th coal and great effect on 15^th coal.
