摘　　要：在松软围岩的条件下,如何加快大断面岩巷掘进速度并保证巷道围岩的稳定性,是矿井安全高效生产的前提条件。过理论计算和现场施工相结合,得出巷道宽度在其中起到关键性的作用,合理确定煤巷宽度对矿井安全生产具有重要意义。In the soft surrounding rock conditions,It is the prerequisite for safe and efficient production of the mine to speed up the large section rock roadway driving speed and ensure the stability of surrounding rock. By theoretical calculation and field construction combination,shows the roadway width has the key role,the determination of the fit coal roadway width is great significance to the safety in production of coal mine.

关 键 词：围岩稳定性 宽度优化 煤巷掘进
