Experimental Research and Application of Mining with Paste Material Stowing

Abstract:

Mining with filling technology is not only an important part of green mining but also the ideal methods to solve the environmental issues in coal mining. The coal gangue and fly ash and furnace slag were selected as the stowing material and the SL paste as cementing material. These two kinds of material were processed into a toothpaste-like slurry without dehydration on ground and transport to underground with the help of gravity or stowing pump in order to stowing the goaf and control the movement of superincumbent strata .Industrial test at Xinsan colliery showed that such kind of paste filling material has high early strength, when filling body was used for false roof of work-face, the post-strength requirement of paste filling material can ensuring false roof stability.
