摘要
合理的爆破技术参数不仅可以减少辅助作业时间,提高掘进效率,还能保证巷道的稳定性,降低支护材料消耗。为了获得良好的爆破效果,拟对某矿大断面巷道掘进爆破参数进行优化,通过理论分析研究和现场应用试验,确定某矿大断面的爆破掘进效果与炮眼深度、炮眼直径、掏槽方式、周边眼布置、装药结构之间的关系,然后选择合理的爆破参数用于指导生产。
Reasonable blasting technical parameters can not only reduce the time of auxiliary operation,improve the driving efficiency,but also guarantee the stability of the roadway and reduce the consumption of supporting materials.In order to obtain good blasting effect and blasting parameters to a mine roadway is optimized through theoretical analysis and field test,a certain section of the mine blasting effect and blasting hole depth,hole diameter,cutting pattern,peripheral hole layout and charging structure of the relationship between,to guide the production and blasting parameters reasonable choice.
