摘要
根据晋城长平公司王台铺煤矿的煤层赋存情况以及与煤层相关的围岩条件进行支架的选型计算,并针对15号煤层工作面顶板坚硬稳定、底板极软的地质特点,确定液压支架的具体结构,设计ZZ6000/17/32型支撑掩护式液压支架。
This paper makes analysis for selection of the support type on base of the coal seam occurrence and surrounding rock conditions of Wangtaipu coal mining belong to Jincheng mining development Co., Ltd. The XV coal seam face has the condition that the roof is stable, the floor is very soft. According to such special geological conditions, the support structures are designed and the ZZ6000/17/32 chock-shield-type support is developed.
