摘要
为解决沿空巷道支护问题,以湖西矿井31104运输巷为研究对象,分析现有支护下巷道破坏特征及破坏原因,提出巷道支护优化方案。运用FLAC3D模拟计算巷道原有支护及支护优化后围岩变形情况,计算结果和监测结果表明,支护优化显著提高围岩强度与承载能力,有效控制巷道变形。
To solve the problem of supporting of gob side entry,research on 31104 haul roadway of Huxi coal mine,analysing the characteristic and causes of deformation,raising up the optimization scheme of roadway support. Simulate the deformation of roadway with original supporting and optimization supporting. Calculation and conclude results show that the strength and bearing capacity of surrounding rock are improved remarkably, and the deformation of roadway is controlled effectively.
