摘　　要：从更新综放设备,改进后部刮板输送机的运输方面考虑,设计放顶煤后部刮板输送机脊背煤回收装置。放顶煤后刮板输送机脊背煤回收装置可以提高采出率,特别是可以减少后部采空区的落煤损失。When design the equipment which is able to recycle the coal from the back of the conveyor behind supports in low caving, renewing the equipment and improving the transportation of the flight bar conveyor in the all mechanic caving mining face should be considered. The recycling equipment behind the flight bar conveyor is able to increase the mining rate, as result of decreasing the lost coal from the goal.
