摘　　要：西部矿区煤炭资源大规模开采过程中,面临顶板水害威胁。本文以受直罗组巨厚砂岩含水层影响较大的枣泉煤矿为研究对象,构建了矿区含水层富水性评价模型,确定了矿区弱、较弱、中等、较强和强共5类富水性分区及矿区安全、预警、危险和非常危险共4类突水危险性分区;探究了富水性分区和开采方式对地下水流场演化规律及工作面涌水量的影响,提出了基于工作面涌水量控制的开采布局设计方法,并在枣泉煤矿130203工作面进行工程应用,验证了预测结果的准确性和工作面布局的合理性。研究结果为西部矿区井下防治水提供了理论指导,对井田顶板水害防治和水资源保护提供了科学的决策依据。During the process of large-scale mining of coal resources in western mining area,the roof water damage is threatened.Taking zaoquan coal mine as the research object in this study,which is greatly affected by the huge thick sandstone aquifer of Zhiluo Formation.An evaluation model of aquifer water abundance in the mining area was constructed.Five water-rich zones(weak,weak,medium,strong and strong)and four water-inflooding zones(safe,early warning,dangerous and very dangerous)were determined.The influence of water-rich zoning and mining mode on the evolution law of underground water flow field and the water inflow of working face was explored,and the mining layout design method based on the control of water inflow of working face was proposed,which was applied in 130203 working face of Zaoquan Coal Mine to verify the accuracy of prediction results and the rationality of working face layout.The research results provide theoretical guidance for underground water prevention and control in western mining areas,and provide scientific decision-making basis for roof water control and water resources protection in mining fields.
