复杂耦合条件下大角度俯采技术

Large-angle Underhand Stoping Technology under Complex Coupling Conditions

针对辛置煤矿10-428C综采工作面倾向倾角大,工作面副巷俯采角度达到20°,以及过断层顶板破碎及液压支架严重老化等难题,在对采煤工艺及设备改进、加强现场管理等方面的进行了研究和应用,实现了安全高效生产。

The 10-428C fully mechanized mining face in Xinzhi Coal Mine has a large inclination angle,the subduction angle of auxiliary roadway in working face reaches 20°,and the problems of serious aging of hydraulic support and roof breakage when crossing faults,etc.In this paper,the mining technology,equipment improvement and field management are studied to achieve safe and efficient production.
