条带煤柱工作面冲击地压与"分级压裂"卸压模式研究
Study on rock burst and"graded fracturing"pressure relief mode in strip coal pillar working face
摘要
Abstract
In view of the problem that the lateral abatement pressure of both sides of the mined working face was transferred to the strip coal pillar during the recovery process of No.3314 Face in Liangbaosi Mine,the stress level often reached or exceeded the stress condition of rock burst,and the impact risk was high,hydraulic fracturing technology was proposed to form a pressure relief mode of"hierarchical fracturing"for pressure relief.According to the site conditions of No.3314 Face,engineering applications were carried out.After the field application,during the excavation and mining of No.3314 Face,the ore pressure was not obvious,and there was no sign of impact.关键词
