摘要

为解决大断层影响推采进度、常造成工作面被迫停采的问题,山东新巨龙能源公司提出了在综采工作面采用深孔预裂爆破过大断层工艺,对爆破巷布置及深孔预裂爆破参数进行分析论证。实践证明,深孔预裂爆破可切实提高过大断层的效率,为工作面高效推采提供了保障。
        In order to solve the problem that large faults affect the mining progress and often cause the face to be forced to stop mining, Shandong Xinjulong Energy Company proposed to adopt the technology of deep-hole presplitting blasting over-large faults in fully mechanized mining face, and analyzed and demonstrated the layout of blasting roadway and the parameters of deep-hole pre-splitting blasting. Practice has proved that deep-hole presplitting blasting can effectively improve the efficiency of overly large faults and provide a guarantee for efficient mining in working face.
