大采高综采工作面过断层关键技术研究

Research on Key Technology of Large Mining Height Fully Mechanized Working Face Crossing Fault

为保证大采高工作面安全高效过断层,以红阳三矿1210-2大采高综采工作面为工程背景,通过相似模拟试验及现场矿压监测的方式,提出了控制采高、沿断层下盘层位推进、伪斜开采、液压支架高工作阻力、追机移架等过断层措施。经现场实践,取得了良好的安全经济效益。

In order to ensure the safety and efficiency of large mining height working face passing through fault,taking the 1210-2 large mining height fully mechanized working face of Hongyang No.3 Mine as the engineering background,through similar simulation experiment and on-site mine pressure monitoring,the measures of controlling mining height,advancing along the footwall of fault,pseudo inclined mining,high working resistance of hydraulic support,and moving machine are put forward.Through field practice,good safety and economic benefits have been achieved.
