单体液压支柱支护在高位壁式正规生产中的应用

Application of Single Hydraulic Props Supporting in High Wall Regular Production

永安煤业有限责任公司丰海煤矿通过在307采区-20C9S工作面开采中采用单体液压支柱支护,实现了高位壁式推采,减少了材料消耗,大幅度提高了回采率,为今后在类似条件采煤工作面推广应用单体液压支柱支护进行正规生产提供了有益的经验。

The single hydraulic props supporting was applied at- 20C9S coal face in No. 307 mining area in Fenghai Coal Mine, Yong＇ an Coal Industry Co., Led. The pushing mining along the high position wall was realized. The material consumption was reduced. The rate of recovery was significantly improved. The useful reference was provided for the regular production with single hydraulic props supporting that was popularized and applied at the face in similar conditions in future.
