悬移支架在嘉乐泉煤矿高档普采工作面的应用实践探讨

悬移支架是介于大型综采支架和单体液压支柱之间的一种较为新型的支护设备,具有许多无可比拟的优点。太原嘉乐泉煤矿根据井下煤层赋存情况,大胆变革,采用悬移支架代替单体柱Π型梁的支护方式,提高了煤炭资源回收率,大大节约了材料费用,杜绝了顶板事故,取得了良好的效果,对同类条件机械化矿井实现高产高效具有较高的借鉴价值。

Discussion on the application practice of the cantilever support in the high-grade conventional working face of Jialequan Mine

Cantilever support is a large fully mechanized support and a single hydraulic prop between a relatively new retaining device,and has many incomparable advantages.According to the underground coal seam occurrence situation,Taiyuan Jialequan mine bold change,adopts the suspended support instead of single pillar shaped beam supporting system,improve the recovery rate of coal resources,greatly saves the material cost,puts an end to the roof accident,has obtained the good effect,similar to a mechanized mine to realize high production and high efficiency with high reference value.
