Application of Rock Lane Rapid Excavation Technology in Zhangcun Coal Mine

With mine production increased year by year,unco-ordinated interface between mining and excauating have become increasingly prominent,rock lane excavation in the coal mine construction and production occupies an important position.The factors which affecting the rock lane excavation in Zhangcun coal mine of Jizhong group company were analyzed.Through the introduction of advanced equipment and mechanized lines,a series of measures for rock lane excavation to achieved rapid excavation in south wing roadway were carried out.The rock roadway footage was 309 m in March 2011,which raised resources 3 times than before the implementation of the technology.
