摘要
随着煤矿开采深度的增加，巷道围岩应力也逐渐增大，传统的支护方式已不能满足复杂地质条件下围岩受力的要求。本文根据一450水平电车库充电硐室的地质条件，采用了组合拱支护理论设计了锚网喷支护方案，提出了较为合理的施工参数与施工工艺，充电硐室的支护取得了比较好的效果。
Abstract
With the add of the exploiting depth in coal mine,surrounding rock stress of the roadway increases gradually, and the traditional supporting method can＇ t meet the need of surrounding rock stress. Based on the geological condition of the -450 level and th
