大采高支架在磁窑沟煤矿综采工作面的应用

介绍了磁窑沟煤矿10-2 #煤层及其顶底板的岩石力学性质.按照传统工艺,工作面回收率低,安全条件落后.通过计算选用大采高支架,在实际回采过程中证明所选设备能够满足生产要求,同时大大提高了工作面的安全性和回采率,增加了矿井的经济效益.

Application on Large Mining Height Support in Fully-mechanized Mining Face of Ciyaogou Coal Mine

Introduces the mechanical property of rock in 10^-2#coal seam and roof and floor of Ciyaogou coal mine. According to traditional technique, it is low that recovery rate in work face, safe condition is laggard. Through calculating and choosing to use large mining height support, proves that the equipment of choosing can satisfy production request in practical mining process, at the same time raise greatly percentage extraction of work face and increases economic benefits of the coal mine.
