In order to study the influence of burial depth on the roadway deformation, the deformation data of more than 100 roadways were collected and classified. The results have shown that, in the first 5 days of new digging roadways, the surrounding rock deformation is basically not affected by the buried depth. The influence period of roadway deformation with different depths is the same, namely, the severe period (1∼15 days), the mitigation period (15∼35 days), and the stable period (35∼50 days). With the increase in depth, the surrounding rock deformation increment of new digging roadways with a depth of 300∼600 m is much larger than that of 600∼900 m. Within 100 m of the working face from the monitoring point, the deformation of mining roadways can be divided into two stages: severe impact (10∼60 m) and stable impact (60∼100 m). With the increase in depth, the deformation increment of the surrounding rock in the mining roadways with a depth of 600∼900 m is much larger than that of 300∼600 m. The surrounding rock deformation increases with the increase in the width and height of roadways and gradually increases with the decrease in the strength of rock mass.

埋深对巷道围岩变形影响规律分析

为了研究埋藏深度对巷道变形的影响，收集并分类了100多个巷道的变形数据。结果表明，在新开挖巷道的前5天，围岩变形基本上不受埋深影响。不同深度巷道变形的影响期相同，即严重期（1〜15天），缓解期（15〜35天），稳定期（35〜50天）。随着深度的增加，深度为300〜600m的新掘进巷道围岩变形增量大大大于600〜900m。在距监测点100 m的工作面内，采矿巷道的变形可分为两个阶段：严重冲击（10〜60 m）和稳定冲击（60〜100 m）。随着深度的增加，深度为600〜900m的采煤巷道围岩的变形增量要比300〜600m的大得多。围岩变形随巷道宽度和高度的增加而增加，随岩体强度的减小而逐渐增加。
