短壁机械化开采技术在小窑残留煤柱回采中的应用

Application of Short-wall Mechanized Mining Technology in Residual Coal Pillar Recovery of Small Mine

针对平朔安家岭井工二矿29213小窑采空区残留煤柱回采情况,从巷道布置、设备配置、回采工艺、工作面通风、顶板管理等几个方面介绍了连续采煤机短壁机械化开采技术的应用。现场实践表明连续采煤机短壁机械化化开采技术具有机械化程度高、适应性强、安全性好等特点;该技术的成功应用也为现代化的大型矿井的残留煤柱回采,提高矿井资源回采率,提供了切实可行的技术解决途径。

Aiming at the recovery situation of residual coal pillar at 29213 gob area in Pingshuo Anjialing No. 2 Mine, from the aspects of roadway layout, layout equipments, mining technology, ventilation at working face, roof management, we introduce the application of short - wall mechanized mining technology by continuous miner. The practice showed that short - wall mechanized mining technology by continuous miner had the characteristics of high degree of mechanization, high adaptability, and good safety. The successful appli- cation of this technique for residual coal pillar mining in modernization large coal mine provides a feasible technical solution for impro- ving the recovery rate of coal resources and increasing the economic benefit of enterprises.
