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。
In view of the influence of mining on the high-grade general mining face, which leads to the serious occurrence of the advanced mine pressure, through the observation of the rock pressure and the deformation of the roadway in the inlet and return airways of the 15031 working face of No.3 Mine, the author combined the computer simulation Results The variation of the working pressure and the deformation of the roadway at the measuring point of the inlet and return airways were analyzed. The reasons for the occurrence of this type of underground pressure and the scope and form of the advance support were determined by the observation results.
