综掘工作面“V”字型出煤系统的研究与应用

Research and Application of "V"-shaped Coal Extraction System for Comprehensive Mining Faces

漳村煤矿通过对综掘开口拐弯出煤系统的优化,避免了综掘直接开口拐弯形成的大断面给顶板管理带来的难题,同时减轻了工人的劳动强度,提高了掘进效率,有效保障了矿井采掘衔接,为今后同类工程施工提供了经验。

By optimizing the system of turning and turning coal,the zhangcun coal mine avoids the difficulties that the large section formed by digging and directly opening turns brings to the top plate management. At the same time,it reduces the labor intensity of the workers,improves the efficiency of excavation,and effectively guarantees the connection of mine excavation. It provides experience for similar projects in the future.
