摘要
为了解决潘三矿1642(1)大断面切眼的支护及施工技术难题,实现工作面的快速接替,分析了大断面切眼的支护原理,提出了锚网索、T3钢带和单体液压支柱配合工字钢挑梁的联合支护方式。同时根据一次成巷与二次成巷的优缺点对比,最终确定采用分次交替掘进、一次成巷的施工方案并取得了良好的社会经济效益,为类似条件下大断面切眼巷道的施工提供了很好的借鉴和参考。
In order to solve the support and construction technical problems occurred in 1642 （1） large-sectioned open-off cut of Pansan Mine, and realize the prompt succeed among working faces, the support mechanism of large-sectioned open-off cut was analyzed, and furthermore, the collaborative support program consist of anchor-cable, ＇IB steel strip and joist cantilever beam suited with single hydranhc bracket was put forward. Besides, according to the comparison of advantages and disadvantages of disposable and secondary roadway formation, the final construction program, including graded alternately tunneling and disposable roadway formation, were adopted and achieved good social and economic benefits, which further provided reference for roadway construction in large-section open-off cut under similar conditions.
