| 摘 要： | 通过理论分析和现场观测,研究了补连塔煤矿采用辅巷多通道的回撤方式进行搬家倒面的矿压特征规律,介绍了综采工作面辅巷多通道主回撤区岩层控制的基本对策--主动支护和被动支护相结合,其中主动支护采用锚杆、锚索、网片等顶板加固来提高围岩自承能力的方法。这一研究成果可给同类条件下的矿井提供参考。

| Abstract: | By theoretic analysis and field observation,the study focuses on strata behavior characteristics in the process of equipment removal with auxiliary multi-channel retreating and introduces strata control measures for the main retreating area: combination of active support and passive support.The active support adopts anchors,cables,and meshes to reinforce roofs in order to increase the self-supporting capability of surrounding rocks.The study can be used in other mines with similar conditions. |
