摘 要:为减少综放工作面停采线保护煤柱留设宽度,提高资源回收率,以某矿2106综放工作面为研究背景,采用理论分析、数值模拟、工程试验等方法,对2106综放工作面停采线位置进行了分析研究。研究结果表明,采用水力压裂切顶卸压技术后,可以将末采保护煤柱宽度由70 m减小为50 m,保护了采区准备巷道的稳定性,提高了煤炭资源的采出率,具有显著的经济效益与社会效益。In order to reduce the width of the protective coal pillar for the stop mining line in the fully mechanized top coal caving face and improve resource recovery rate,taking the 2106 fully mechanized top coal caving face in a certain mine as the research background,theoretical analysis,numerical simulation,engineering experiments and other methods were used to analyze and study the position of the stop mining line in the 2106 fully mechanized top coal caving face.The research results indicate that the use of hydraulic fracturing top cutting and pressure relief technology can reduce the width of the final mining protection coal pillar from 70 m to 50 m,protect the stability of the preparation roadway in the mining area,improve the extraction rate of coal resources,and have significant economic and social benefits.
