Yin Li-jun

Abstract

The roof coal caving technology is a kind of mining method that is applicable to the thicker and 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.
