摘　　要：为有效解决某矿区目前因掘进技术、施工工艺流程、支护工艺等方面存在问题而导致生产效率低下的现象。本文结合该矿区现状进行了综合分析,提出了优化施工方案,巷道掘进速度由11.2 m/d提高至14 m/d,掘进速度较原来相比提高了25%,一方面保证了矿井高效开采,同时也确保了薄基岩下煤层采掘的安全性。In order to effectively solve the phenomenon of low production efficiency caused by problems in excavation technology,construction process,support technology,etc.in a certain mining area,this article conducts a comprehensive analysis based on the current situation of the mining area and proposes an optimized construction plan.The tunneling speed has been increased from 11.2 m/d to 14 m/d,which is a 25% increase compared to the original.On the one hand,it ensures efficient mining of the mine,and on the other hand,it also ensures the safety of coal seam mining under thin bedrock.
