摘要
为了加快巷道掘进速度,降低掘进成本,保证巷道安全施工,通过分析303盘区2304系统巷原施工方案及主要存在的问题,对其施工方案进行优化设计。实际应用效果表明,施工方案优化后减少巷道掘进长度90m,降低巷道掘进成本费用达72万元。
In order to accelerate the speed of roadway excavation, reduce the cost of roadway excavation and ensure the safe construction of roadway, the original construction scheme and main problems of 2304 system roadway in 303 pan area were analyzed, and its construction scheme was optimized. The practical application results show that after optimization of construction scheme, the length of roadway driving is reduced by 90 m and the cost of roadway driving is reduced by 720,000 yuan.
