影响炮眼布置的主要因素是岩石性质、巷道断面的大小、钻眼设备、炮眼深度和炸药性能等。文章主要介绍了掏槽方式的选择与布置,辅助眼及底眼布置,岩巷掘进的光面爆破技术等问题。
The main influence factors of blast holes arrangement are rock nature,the cross-section size of roadways,drilling equipments,the depth of blasting holes and explosives performance.Some problems are introduced in the paper,such as selection and arrangement of cut ways,arrangement of reliever holes and bottom holes,and smooth blasting technology in the rock roadways driving.
