摘　　要：依据矿区范围内的补勘、采掘工程揭露、钻探资料,阐述了刘庄煤矿1煤赋存情况和顶板岩性特征。选取砂泥比、含水层厚度、平面变形系数、断层分维值、岩石质量指标等五项影响顶板富水因素,采用传统的层次分析法(AHP)对刘庄矿井1煤层顶板富水性进行评价并根据评价结果提出针对性防治水措施。总体来看富水性在区域上存在差异,其中东三采区富水性最为充沛,含水较丰富区主要分布在西三采区,含水中等区分布于西一采区与东一采区南部,含水少量区分布于西四采区东的南部。根据评价结果以及结合采掘和开采方法,建议健全水文地质观测网络系统,标定煤层层位,使用物探方法进行超前探测及注浆加固治理等措施。According to the supplementary exploration,mining engineering exposure and drilling data in the mining area,the occurrence and roof lithology characteristics of No.1 coal seam in Liuzhuang Coal Mine are expounded.Five factors affecting roof water abundance,such as sand-mud ratio,aquifer thickness,plane deformation coefficient,fault fractal dimension value and rock quality indicators,were selected.The traditional analytic hierarchy process(AHP)was used to evaluate the roof water abundance of No.1 coal seam in Liuzhuang Mine and the targeted water prevention and control measures were proposed according to the evaluation results.In general,there are differences in water abundance in the region.Among them,the water abundance of the Dongsan mining area is the most abundant.The relatively water-abundant areas are mainly distributed in the Xisan mining area;the medium water-abundant areas are distributed in the Xiyi mining area and the south of the Dongyi mining area,and the least water-abundant areas are distributed in the south of the east of the Xisi mining area.According to the evaluation results and the combination of mining and mining methods,it is recommended to improve the hydrogeological observation network system,calibrate the coal seam level,and use geophysical prospecting methods for advanced detection and grouting reinforcement.
