Abstract

Abstract: Stoping with paste filling technology to mine is used in 2351 working face of Daizhuang coal mine.For solving mortar leakage problem on the filling process，we put forward the view of setting up separating wall in filling areas and using gangue backfill paste of higher concentration and large grains in size to block the leakage，which has achieved good performance in the pratical application.

Key words: Paste filling, Separating wall, Mortar leakage, Plugging
