摘　　要：为探究水力压裂在煤矿顶板卸压中的应用效果,以恒源煤矿Ⅱ636工作面为背景,利用FLAC3D软件对矿压显现规律进行模拟分析,并探讨系统巷道在采动过程中的响应特征。研究结果表明:当工作面开采达到120 m时,系统巷道受到采动影响,且随着工作面的不断推进,影响程度逐渐加剧,确定6.1 m的细砂岩为采动应力提供传递介质;压裂后顶底板最大变形量为49 mm,两帮最大变形量为10 mm,说明采取水压致裂的方式,对采动应力进行阻断和转移,达到对系统巷道的控制与保护。To explore the application effect of hydraulic fracturing for roof pressure relief in coal mines,this study takes the Hengyuan Coal Mine II 636 working face as the background and utilizes FLAC3D software to simulate the manifestation laws of mining pressure.The research investigates the response characteristics of the system roadway during the mining process.The results indicate that when the working face reaches a mining depth of 120 meters,the system roadway is affected by mining activities,and this impact intensifies as the working face continues to advance.A layer of fine sandstone at a depth of 6.1 meters is identified as the medium for transmitting mining-induced stress.After fracturing,the maximum deformation of the top and bottom plates reaches 49 mm,while the maximum deformation of the two side walls is 10 mm.This demonstrates that the method of hydraulic fracturing effectively blocks and transfers mining-induced stress,thereby achieving control and protection of the system roadway.
