【Abstract】 From the three aspects of the fully mechanized slice mining technology in thick seam,the fully mechanized top coal caving mining technology and the fully mechanized high cutting and top coal caving mining technology,introduced the development and present status of the mining technology in Lu’an mining area.Taking the 6203 coal mining face in Wangzhuang Mine as the example,stated the innovation conception and the industrial research on the fully mechanized high cutting and top coal caving mining technology in Lu’an mining area.The industrial trial results show that the mining rate of the coal mining face can reach at 91.6% in average,the max mining rate can reach at 92.1%,the max month production can reach at 33 186 t and the max work efficiency is 502 t/shift.更多还原
