内蒙古利民煤矿大断面井筒爆破设计

Large section borehole blasting design of Inner Mongolia Limin Mine

井筒爆破主要参数有炮眼深度、药卷直径、炮眼直径、炮眼数目和炸药消耗量等,应根据井筒施工的地质条件、岩石性质、钻眼机具和爆破方式等因素综合考虑,合理确定适用井筒工作面的爆破参数。

Blasthole depth, cartridge diameter, blasthole diameter, blasthole number and consumption of explosives are the main parameters of borehole blasting, geological conditions, rock properties, drilling machines and blasting way should be considered comprehensively to settle the reasonable blasting parameters of borehole working face.
