| Abstract: | Based on the geological conditions and features of Shaping mine,the paper analyzes strengths and weaknesses of three mining modes: hierarchical fully-mechanized mining,top coal caving and whole-height mining.The whole-height mining technology was selected to be used in the working face and the daily output of 7684.84t and recovery rate of 93.7% were achieved.The mode proves to be reasonable due to its significant economic benefit. |
