巷道掘进通防技术研究

Research on the General Defense Technology of Roadway Tunneling

本文以店坪掘进巷道为工程案例,介绍了巷道掘进过程中的瓦斯,粉尘及灭火技术问题。经现场实践,瓦斯浓度得到有效控制,有效降低粉尘浓度,希望其方法能为同地质条件矿井巷道掘进通防问题提供参考。

Taking the road tunneling of Dianping Coal Mine as an example, the paper discussed the problem of gas, dust and fire extinguishing in roadway tunneling and put forward the general defense technology of roadway tunneling. It proved that after adopting this technology, the gas concentration is effectively controlled, and the dust concentration is reduced effectively, which provides a useful reference for the problem of roadway tunneling in the mine roadway.
