岩巷掘进效率的影响因素与提升对策

摘要

At present, the drivage still gives priority to blasting eyes, but with the mine production increased year by year, the fast tunneling of rock in coal mine construction and production arouse more and more attention, how to improve blasting efficiency, and to ensure the blasting effect, as well as to ensure the realization of forming and fast tunneling have become the main problems needed to resolve. In this paper, combined with the practice in coal mines, the influencing factors was analyzed and the corresponding countermeasures was put forward from blasting technology and construction management about how to improve rock blasting effect and circulation footage, this can be reference for travel together.%目前，岩巷掘进仍以钻眼爆破为主，但随着矿井产量的逐年增加，岩巷快速掘进在煤矿建设和生产中越来越受到关注，怎样提高爆破效率、优化爆破效果、保证巷道成型和实现快速掘进都成了急需解决的问题。针对如何提高岩巷爆破效果和循环进尺的问题，结合在煤矿的实践，分析了影响岩巷掘进效率的因素，并从爆破技术和施工管理上提出了相应的提升对策，供同行借鉴与参考。
