摘要
针对常村煤矿底板瓦斯预抽巷掘进过程中,遇到坚硬岩石,造成掘进机截齿消耗量大、掘进机磨损的问题,提出了松动爆破过硬岩的方法,并设计了相应的爆破参数及安全技术措施。实践表明,实施该措施可顺利通过硬岩区域,为类似条件下岩巷掘进提供参考。
Based on the hard rock causing high consumption of mining machine cutting pick and machine wear in floor gas pre-drainage mining of Changcun Mine, loosening blasting crossing hard rock was put forward, corresponding blasting parameters and safety technical measures were designed. The result showed that the implementation of technology could cross hard rock region, which provided reference for similar rock roadway mining.
