为了防止多煤层开采后遗留下的多重煤柱及顶、底板矿压动力显现,基于煤峪口矿14#层的赋存和开采技术条件,经研究确定对51006巷上覆煤柱及坚硬顶板实施弱化爆破卸压技术,并计算、分析得出合理的爆破参数。
In order to prevent the occurrence of multiple coal pillars and top and bottom strata motive forces left over by multiple coal seam mining, based on the occurrence and mining technical conditions of layer # 14 in Meiyukou coal mine, the study confirmed that the coal pillar over 51006 lane and the hard roof The implementation of weakening blasting pressure relief technology, and calculated and analyzed the reasonable blasting parameters.
