边角煤回收的防冲问题已引起许多学者的关注,边角煤的赋存条件复杂,经分析得出,边角煤在回收过程中的冲击危险性非常的高。以兴隆庄煤矿的B1302边角面为研究背景,从地质构造、工作面布置及开采技术条件等方面对该工作面的冲击危险性进行了分析。划分了该工作面的重点防冲区域,提出了在开采期间需要采取的几项防治措施,B1302工作面的工程实践验证了防冲措施的有效性,所得结论对具有类似条件边角煤回收的冲击矿压防治工作有一定指导意义。
The anti-scalding problem of corner coal recovery has attracted the attention of many scholars. The conditions for the corner coal production are complicated. The analysis shows that the impact risk of corner coal in the recovery process is very high. Taking the B1302 corner face of Xinglongzhuang Coal Mine as the research background, the impact risk of the working face was analyzed from the aspects of geological structure, face layout and mining technical conditions. The key anti-scouring area of the working face is divided into several prevention and control measures which are taken during the mining period. The engineering practice of B1302 working face verifies the effectiveness of the anti-punking measures. The conclusions obtained are as follows: Rock burst prevention and control work has some guiding significance.
