Abstract

Abstract:

Using a partial backfill mining is an effective way to protect the roof of water resisting layer the special water preserved shallow seam mining. It is important to research the factors of the amount of water resisting layer sinking in the local filling cracks in shallow seam,for determining a reasonable filling parameters guide the mining practice of partial filling is very important theoretical and practical significance. Based on physical similar simulation, it determined maximum subsidence of water resisting layer is composed of subsidence of filling material above the supporting pillar of the subsidence bedrock confining layer. Among them, the subsidence of filling is positive related to ratio of filling width and filling the width of the interval,in the ratio of filling width and filling the width of the interval, the subsidence of filling is positive related to the corner with the rock collapse,above the support pillar and the influencing factors relations with the filling of the compression is similar to the amount of bedrock sinking impermeable layer impermeable layer and the bedrock negative correlation, with the filling width decreases, the impermeable layer of bedrock subsidence curves similar to the hyperbolic shape upward.It is showed that the result of mathmatics of the amount of water resisting layer sinking is equal to physical similar simulation,which provid scientific theoretical basis for partial backfill in shallow seam.

Key words: shallow seam, Longwall Partial Backfill Mining, the amount of aquifuge sinking, aquifuge, water conservation mining, simulation materials
