主要进风巷快速施工组织及工艺优化

Fast Construction Organization and Process Optimization of Main Air Inlet Roadway

针对煤矿井下大断面岩巷掘进效率低、工艺落后的现状,古城煤矿在主要进风巷施工过程中采用分段掘进、差异化支护等施工组织及优化工艺,加快了全巷道掘进速率,对大断面巷道快速施工具有一定的借鉴意义。

In view of the low efficiency and backward technology of large cross-section rock roadway excavation in underground coal mine,Gucheng Coal Mine adopts the construction organization and optimization technology of subsection excavation and differential support in the construction process of main air entry roadway,which speeds up the whole roadway excavation rate and has certain reference significance for the rapid construction of large cross-section roadway.
