摘要
针对高档普采工作面受采动影响,造成超前矿压显现剧烈的问题,通过在教学三矿15031工作面进、回风巷进行现场矿压及巷道变形量的观测,并结合计算机模拟计算的结果,分析进、回风巷测点处单体液压支柱工作阻力及巷道变形量变化规律,利用观测结果寻求这种矿压显现现象的原因并确定超前支护的范围及形式。
Aiming at problem of severe strata behavior caused by mining affecting at high - grade conventional coal face. Rock pressure monitoring and roadway deformation were carried out at intake and return airway of 15031 working face in Jiaoxue No. 3 Coal Mine. The working resistance of single hydraulic prop and the surrounding roadway rock deformation laws at measuring points were analyzed com- bined with the results of computer simulation, which is used to point out the cause of severe strata pressure and determine the form and range of advanced support.
