摘要
Abstract
The roof-cutting roadside support of the stope is the important and difficult point of the large diameter subsequent filling mining method,the support scheme seems to be very important,the roof support scheme is proposed for the large diameter long-hole lateral caving subsequent filling method,we overall analyzed the unstable factors of roof-cutting roadside support,and proposed the arrangement of pillars on both sides of roof cutting,as well as the arrangement of prestressed anchor-anchor cable method,the monitored volume of movement of the roof area is only 5.97 mm,then the roof stability is increased greatly,it can provide references of the roof support scheme of the mining area to similar mines.关键词
