摘要
文章主要阐述了综采工作面固体(矸石)充填沿空留巷技术的留巷支护方式及其施工工艺,并通过两种支护方案的对比以及对充填工作面矿压显现的长期观测,最终决定采用锚网索配合π钢梁联合支护的方式。通过后期实践验证,此支护方式能够满足固体充填面的留巷要求,且实现了安全上合理、经济上节约、技术上可行的目的。
This paper mainly discusses the fully mechanized working face solid (waste)filling gob-side entry retaining technology support forms and the construction technology,and through the two supporting scheme comparison and filling face mine pressure revealed in the long-term observation,finally decided to use cable anchor combined withπsteel beam joint support way. Through the later practice verification,the supporting method can meet the re-quirements of solid filling left lane,and realize the security,reasonable,economical and feasible in economy,technology on purpose.
