潞安矿区综放开采技术的研究与实践
|
摘要
从厚煤层分层综采技术、综采放顶煤技术、大采高综采放顶煤技术3个方面介绍了潞安矿区开采技术的发展与现状。以王庄煤矿6203工作面为例,详述了潞安矿区大采高综采放顶煤技术的创新思路与工业试验研究。结果表明:工作面采出率平均达91.6%,最高达92.1%;最高月产达33186t;最高工效达502t/工。
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.
