摘要
随着采深增加,深部软岩巷道支护困难已成为煤矿安全生产的重大隐患。分析了深部软岩巷道围岩在不同阶段的变形特征,并在此基础上对该类巷道的主要支护方式的效果及特点进行了研究,提出消除该类巷道围岩岩块非连续性变形破坏是保证支护效果良好的关键所在。
With the mining depth increased,it becomes important hidden danger of coal mine production safety that support of the deep soft rock roadway is difficult.Analyze the deformation characteristics of the deep soft rock roadway at different stages,and on this basis studies effects and characteristics of the main supporting methods.It is the key to ensure good supporting effect that discontinuous deformation of surrounding rock of the roadway is removed.
