Mechanism of Coal Mining and Stowing with Upper Entry for Preventing Coal Bump
The material failure induced coal bump and structure failure induced coal bump were paid attention to in this paper. Mechanism of coal mining and stowing with upper entry for preventing coal bump was analyzed. The mechanism of mining with upper entry for preventing material failure induced coal bump is that the stowing material can recover the integrity of the cracked roof, and for preventing structure failure induced coal bump is that water infusion to the roof could release the energy in the roof, and the backfilling could support the roof, both of them could change the stress condition of the roof. It hopes that coal mining and stowing with upper entry for preventing coal bump is a rational way to realize safety mining, but there still are some questions should be the further studied.
