摘　　要：马家岩煤矿浅层煤炭资源已基本枯竭,太原组(下煤组)的深部煤层是目前主要的连续开采煤炭资源。但随着开采深度逐年增加,下煤组的开采受到高地应力、高水压、高温和强矿井扰动的影响,突水威胁尤为严重。为对太原组煤层开采承压水害进行有效防治,基于煤矿工作面底板含水层的注浆数据,提出煤层底板突水控制的评价新方法,将测试数据与矿山电测数据在ArcGIS中进行比较。结果表明,基于ArcGIS的水压阈值为注浆改造层水压的2倍时为最优解,研究结果可为马家岩煤矿太原组的突水防治提供参考。The shallow coal resources of Majiayan Coal Mine have been basically exhausted,and the deep coal seams of Taiyuan Formation(Lower Coal Formation)are the main continuously mined coal resources at present.As the mining depth increases year by year,the mining of the lower coal formation is affected by high geo-stress,high water pressure,high temperature and strong mining disturbance,and the threat of sudden water inrush is particularly serious.In order to effectively prevent and control the pressurized water hazard in the coal seam mining of Taiyuan formation,based on the grouting data of the coal face floor aquifer,a new evaluation method for the control of water inrush in the coal seam floor is proposed,and the test data are compared with the mine electric measurement data in ArcGIS,and the results show that the water pressure threshold based on ArcGIS is two times of the water pressure of grouting reforming layer,which is the optimal solution.The study provides a reference for the prevention and control of water inrush in the Taiyuan formation of Majiayan coal mine.
