| 摘 要： | 通过现场实测、理论分析和相似模拟实验,研究了急斜特厚煤层水平分段放顶煤开采围岩破坏规律,提出了开采引起的围岩破坏传递主途径和破坏分区,分析了影响各破坏区大小的因素。同时,分析了地表塌陷损害的特点,提出利用自重充填等方法控制采动损害和限制地表破坏。

| Abstract: | Based on the in-site survey,the theoretical analysis and similar material model test,the failure laws of surrounding rock for the horizontal section top caving in steep dip extra-thick coal seam are studied.The major transfer path and divisions of surrounding rock damage caused by mining are presented and the factors effecting the divisions are analyzed.Further,the characteristics of surface subsidence damage are analyzed.At last,the self-weight filling measure is presented to control the mining and surface damages. |

| Keywords: | Steep dip coal seam Surrounding rock damage Surface subsidence Damage division Self-weight filling |
