摘　　要：矿井突水是煤矿生产过程中最具威胁的灾害之一,工作面回采前需对面临的水害威胁进行综合评价与治理。以张双楼煤矿24901工作面为例,针对研究区面临的西翼采区底板四灰高承压、断层及陷落柱构造发育、底板四灰富水差异大等水文地质问题,通过开展四灰含水层分阶段井下放水试验、老空水现场钻孔探放、陷落柱物探钻探综合探查、室内分析测试和理论分析,揭示研究区底板四灰岩溶发育与富水规律,查明老空水积水位置、积水量以及陷落柱发育范围、导(含)水性等,并提出了老空水、西翼底板四灰、陷落柱及断层构造等复合水害综合防治技术体系。相关研究成果揭示了东部矿区普遍面临的煤层底板灰岩水及构造水等水害特征,可为研究区及相似开采条件下矿井防治水工作提供一定的理论及工程依据。Mine water inrush is one of the most threatening disasters in the process of coal mine production,and it is necessary to comprehensively evaluate and control the threat of water disaster before mining in the working face.Taking the No.24901 working face of Zhangshuanglou Coal Mine as an example,in view of the hydrogeological problems faced by the study area,such as the high bearing capacity of the four-ash floor in the west wing mining area,the structural development of faults and collapse columns,and the great difference between the four-ash floor and the water-rich floor,it was planned to reveal the development and water-rich law of the four-ash floor karst in the study area through staged underground drainage test,on-site drilling and exploration of old empty water,comprehensive exploration of geophysical exploration of collapse columns,indoor analysis and test and theoretical analysis.The location,amount,development range and water conductivity of the old empty water were found out,and the comprehensive prevention and control technology system of the old empty water,the four ashes in the west wing floor,the collapsed column and fault structure was finally put forward.The relevant research results reveal the characteristics of water disasters such as limestone water and tectonic water in coal seam floor commonly faced by eastern mining areas,which can provide certain theoretical and engineering basis for mine water prevention and control in the research area and similar mining conditions.
