Abstract: Based on the analysis on the development status of the backfill mining in China, the introduction on the developmentcourse and the research and applic ation of the backfill mining technology and the backfill mode, in combination with the backfill mining practiced in Kailuan, the integrated match of the mining equipment was analyzed and the matching process of the powered support and the backfill conveyor was explained. The matched equipment would not only fully meet the performa nce requirements of the mining technical system with the coal rejects backill, but could have high backfill efficiency and stable performances and could solve the coal r eject backfill matched equipment influenced to the backfill speed.The matched equipment could realize the coal reject handling in underground mine and the full utilizati on of the coal resources under the buildings.
