Abstract
Top-coal caving difficulty degree and rational mining method were analyzed by theoretical method on the basis of the 4th coal-seam condition of Pingshuo Mining area. For improving top-coal caving degree, the parameters of full-mechanized caving mining face were obtained by numerical simulation and the equipments were selected and assorted. Practice showed that safe and high-efficient mining with high recovery ratio would be realized by lengthening mining face and adding mining height in shallow buried hard coal-seam with hard roof.
