爆破工艺的选择对炮采工艺煤炭自装率的影响

Blasting Technique Influencing the Self-Being Rate on Blastdown Technology

文中针对炮采工作面核心工艺──爆破工艺，通过瞬发爆破、微差爆破的试验对比，用作图法分析爆破工艺对炮采工作面煤炭自装率的影响．

In this paper, to counter the key technology of blastdown-blasting technology, compering experimental results of instant blast with those of millisecond blast, the effect of blasting technique on the self-being rate at coalface was analyzed by use of method of description.
