钱营孜煤矿岩巷快速掘进研究及应用

he excavation of various roadway of Qian Ying Zi Coal is slower comparatively, affecting the normal production of replacement. In order to improve the rapid excavation of Rock Lane, to achieve high yield and efficiency of coal.The paper takes the east-one alley tape machine for example.To improve the efficiency, and to ease the tension of mining replacement. By the field measurement and theoretical analysis, to find the blasting parameters. Transportation system and the personnal quality are the main problems which restricts the roadway rapid excavation. By improving the construction Technology and transportation systems, The monthly drilling depth of roadway increases from 62m to 100m, to achieve a normal replacement of the face . and to provide the conditions for future expansion.
