摘要
为促进工作面顺利通过陷落柱,以潞安集团某煤矿1303工作面胶带巷过DX7陷落柱为例,提出了该胶带巷过陷落柱时的具体支护方案,包括临时支护、锚网支护以及工字钢棚支护等联合支护技术,简述了主要施工顺序,实际支护结果表明,采用锚网+工字钢棚进行支护作业,支护效果良好,保障了巷道支护强度。
In order to promote the smooth passage of the working face through the collapse column, taking the 1303 working face of a coal mine in Lu’an Group as an example, the concrete support scheme of the slide column in the rubber belt roadway is put forward, including temporary support, bolting mesh support and I-steel shed support and other other joint support technology, the main construction sequence is briefly described. The actual support results show that the bolting mesh I-shaped steel shed is used to support the the support effect is good, and the roadway strength is guaranteed.
