摘要
传统高抽巷掘进施工效率低下且安全性无法保障,本文以某煤矿工作面高抽巷为例,分析支护参数、爆破方式,并采用联合支护、全断面一次起爆等技术,实现了工作面高抽巷高效掘进,现场实践效果显著.
Abstract
Traditional high extraction roadway excavation has low efficiency and safety cannot be guaranteed.This article takes a coal mine working face high extraction roadway as an example,analyzes the support parameters and blasting methods,and adopts technologies such as combined support and full section one-time blasting to achieve efficient excavation of the working face high extraction roadway.The on-site practice effect is significant.
