摘要
为了提高深部巷道掘进过程中爆破效率、保证掘进速度,提高巷道成型质量,文章以陈四楼煤矿2517胶带运输巷(岩巷段)的掘进为工程背景,分析了影响深部岩巷爆破掘进的因素,并结合具体施工条件,合理设计爆破参数,保证了巷道的循环进尺和周边成形质量,其施工思路与方法可为类似条件下的岩巷掘进提供借鉴和参考。
In order to enhance the blasting efficiency during the driving in deep roadway, to insure the driving speed and to improve the roadway forming quality. Based on the driving project of the 2517 belt haulage roadway （rock roadway section） at Chensilou coal mine, the reasonable blasting parameters were designed, through the analysis of factors affecting the blasting driving in the deep rock roadway, combning with the specific construction conditions. The Roadway cyclical footage and surrounding forming quality were guaranteed. Ideas and methods of the construction, the drilling - and -blasting method for driving in rock roadway at Chensilou Coal mine can offer references for similar situation.
