摘要
井下巷道采掘交替的日益紧张已经逐渐成为制约矿井生产作业效率增长的重要因素之一,实现巷道掘进的快速开展对矿井生产高效进行意义重大。在总结阐述矿井大断面巷道快速掘进保障工艺的基础上,结合具体实例对巷道快速掘进施工的开展进行了分析。实际结果表明优化后的掘进作业方案实现了掘进速度的增加,为矿井生产效益的增长提供了有力支撑。
The increasingly tensing alternation of excavation and mining in underground roasdways has gradually become one of the important factors restricting the efficiency of mine production operations.The rapid development of roadway excavation is of great significance to the efficient production of mines.On the basis of summarizing the rapid excavation guarantee process of mine large section roadway,this paper analyzed the development of rapid roadway excavation construction with concrete examples.The actual results show that the optimized excavation operation scheme achieves an increase in the excavation speed and provides a strong support for the growth of mine production efficiency.
