Optimal Design of Laneway's Side Support for Gob-side Entry Retaining with Solid Cemented Backfilling
摘要
Abstract
To improve the effect of gob-side entry retaining with solid cemented backfilling,we present optimum design of the support for laneway's side through taking 9301 backfilling mining face of Tangkou Coal Mine as the background.We analyze the inner link and laws between the basic characteristic of the filling slurry and the ratios of the cemented filling material through studying bleeding rate,strength of the cemented filling material,and select the best ratio of cemented filling material in laneway's sides of Tangkou Mine.Experimental results on 9301 backfilling mining face of Tangkou Coal Mine illustrate that optimum design of the support for laneway's side has the features of fast setting,early strength and better packing quality,and the deformation of gob-side entry is effectively controlled.关键词
