摘要
放顶煤技术是适用于煤层较厚、煤质松散的煤层开采的一种方法。残煤开采是将过去已开采区留下的煤柱、不可采的煤柱,再进行复采。文章就放顶煤技术在残煤开采中遇到的有关问题做一般性分析,仅供参考。
The roof coal caving technology is a kind of mining method that is applicable to the thicker anct loose coal seam. In the residual coal mining, the retaining and non - mining pillars in the mined area in the past are for resumption of mining. In the paper, the mining - related problems in the residucal coal mining are generally anaylized, for reference purposes only.
