摘要
阐述巷道超前卸压爆破技术现状,分析了神宁集团枣泉煤矿11201工作面回风巷出现构造应力的影响因素,提出了采用超前卸压爆破技术在掘进前释放围岩应力的方法和措施,通过对其进行总结分析,从而为其他类似巷道的围岩应力释放积累宝贵的经验。
This article sets forth the present situation of advanced bore decompression explosion technology, analyses the affecting factors of structure stress occurred in ventilation roadway on No. 11201 working surface of Zaoquan Mine of Shenhua Group. Measures are put forward to release wall rock stress before digging via application of advanced decompression explosion technology. Such experiences can be used to release stress in similar situations.
