摘要
Abstract
The lower recovery ratio of top-coal in fully mechanized caving face is a main problem , and improving the recov-ery ratio of top-coal has great significance to the high production and high efficiency of fully mechanized caving mining . Based on actual practice of №401102 fully mechanized caving face in Hujiahe Mine , the crushing mechanism and cavability of top-coal was researched , and the influence of different way of moving supports to the recovery ratio of top -coal is analyzed too.关键词
