摘要
陈四楼煤矿-720 m水平岩巷掘进采用钻爆法,由于巷道施工断面大、地质条件复杂、排矸系统单一、工序繁多,导致劳动效率底下,月进尺低,严重影响岩巷掘进速度。在施工-720 m辅助水平轨道巷(里段)时,优化出矸方式及凿岩方式,稳抓正规循环,组织紧凑,施行严格的工程技术管理,效果明显。
Chensilou coal mine-720 m horizontal rock drivage by drilling and blasting method,because of the large cross section of roadway construction,complex geological conditions,a single conveyor system,working procedure is various, cause under the labor efficiency,low penetration,serious influence on the speed of rock drivage. Chensilou coal mine in construction-720 m auxiliary level track lane( period),optimize the way out of the bottles and drilling,catch a normal cycle,organization is compact,engineering management,strict implementation overproduced.
