采用大孔距小抵抗爆炸技术的关键是求出最佳破碎抵抗线，从而获得ａ／Ｗ之最佳值（ａ—爆破影响范围；Ｗ—最佳破碎抵抗线）。沙坝矿应用实践表明其ａ／Ｗ的取值范围在２．５～４之间。通过增加孔距，可获得较大的孔网面积，提高延米爆破量。采用合理起爆顺序和间隔装药能...
The key to using low-pitched MRT technology is to find the best crushing resistance line to obtain the best value of a / W (a-blasting range; W-best crushing resistance line). Sand dam application shows that its a / W value range between 2.5 to 4. By increasing the hole distance, a larger area of the hole network can be obtained and the blasting amount of the delay meter can be increased. Using a reasonable order of initiation and interval charge can ...
