我矿主要是采用有底柱采矿方法的矿山,多年来的实践证明,要扩大生产规模或适应强采的需要,必须扩大一次爆破崩矿量的规模,以便减少爆破次数、准备时间及因爆破而影响的生产时间。此外多矿房、分段在挤压状态下爆破不仅可以降低崩下矿石的块度,而且可以降低矿石的损失率和贫化率。扩大一次爆破崩矿量就需要爆破大量炮孔(相应地要起爆大量电管)。大量电管起爆的网路设计是整个大爆破设计中的 Mine is mainly mine with bottomed column mining method. Over the years, practice has proved that to expand production scale or adapt to strong mining needs, it is necessary to expand the scale of one blasting collapse and disintegration so as to reduce the number of blasting, preparation time and blasting The impact of the production time. In addition, more mines and sub-sections in the extrusion state blasting can not only reduce the collapse of ore block, but also reduce the ore loss and dilution rate. Explosion blasting a large amount of blasting requires a lot of blasting holes (corresponding to a large number of detonated tube). A large number of tube detonation of the network design is the big blasting design
