顶煤松动爆破技术的研究

Research on loose blasting technology for top coal

应用爆破松动圈、近似等值抵抗线和灰色决策等理论确定松动爆破有关参数,在开滦矿务局马家沟煤矿取得了明显的经济效果。

The paper had set up the related parameters of the loose blasting with the loose blasting circle, approximated equivalent resistance line and gray decision theory Those related parameters applied to Majiagou Mine of Kailuan were obtained with obvious economic benefits The successful experience of the technology has a certain reference to the mines with the caving mining production
