复杂地质条件下富水岩巷炮掘施工技术探讨

Discussion on the Construction Technology for Blasting in Water-rich Rock Roadway under Complex Geological Condition

复杂地质条件下富水岩巷掘进受多方面条件制约,在该种条件下推广光面爆破存在很多困难。本文通过对双马煤矿I01采区边界泄水巷Ⅳ段岩巷掘进炮掘工艺进行科学分析,对同地质条件下岩巷炮掘施工工艺相关参数进行了总结,并提出了优化建议,对后期该矿岩巷施工具有一定的指导意义。

The excavation of water-rich rock roadways under complex geological conditions is restricted by many conditions. There are many difficulties in promoting smooth blasting under such conditions. In this paper, through the scientific analysis of the tunnel excavation and blasting technology in the Ⅳ drainage lane at the boundary of the I01 mining area in Shuangma Coal Mine, the relevant parameters of the blasting and excavation construction process in the rock roadway under the geological conditions are summarized, and the optimization suggestions are put forward. The mine rock lane construction has a certain guiding significance.
