摘　　要：The formation of the paste like backfill technology was introduced briefly in this paper. From the actual cases of coal mines, a new mode of coal mining under buildings with the technology was proposed. And its specificity was analyzed, and a further introduction to the full sand soil solidifying material was given. The main parts of the backfill system, such as the backfill preparation system, the pipeline transportation system, the backfill systems in fully mechanized mining faces and the backfill process, were presented emphatically.The formation of the paste like backfill technology was introduced briefly in this paper.
