急倾斜煤层水平分层综采放顶煤采煤法,尤其是对于短臂综采工作面,要实现高产高效有一定的难度;急倾斜煤层短臂综采放顶煤开采的应用实践中,通过不断改进采煤工艺,技术创新,2007年已基本上实现了急倾斜煤层综采放顶煤的高产高效。在实践中已实现了平均日产2000吨以上,回采率85%以上,并开创了日产2400吨,回采率达93%的好成绩,这主要是在劳动组织和采煤工艺上二者得到了很好的结合,并取得了很好的效果。
Especially for the short-arm fully mechanized coal mining face, it is difficult to achieve high productivity and high efficiency. In the practice of short-leg fully mechanized top coal caving mining with steep inclined seam, Through continuous improvement of coal mining technology and technological innovation, the high yield and high efficiency of fully mechanized top coal caving with steep seam has been basically achieved in 2007. In practice, it has achieved an average daily output of more than 2,000 tons and a recovery rate of over 85%, and has created a good result of 2,400 tons per day and a recovery rate of 93%, mainly because both the labor organization and the coal mining technology have achieved very good results Good combination, and achieved good results.
