良好有效爆破的要求如下:(1)采用恰当的爆破形式提供充足的能量;(2)有效地释放炸药的全部能量;(3)在岩体中正确布置炸药;(4)飞石、地震和空气冲击波应保持在规定的限度内;(5)费用低廉和高度安全。钻孔精度最小抵抗线和孔间距不变,爆破结果是相同的。不精确的钻孔会改变个别最小抵抗线和孔间距,使爆破结果不一致。其影响程 The requirements for good and effective blasting are as follows: (1) Adequate energy is provided in the form of an appropriate blasting; (2) Effective release of the full energy of the explosive; (3) Proper placement of explosives in the rock; (4) Flyash, earthquakes and Air shock wave should be kept within the prescribed limits; (5) low cost and high safety. Drilling accuracy minimum line and hole spacing unchanged, the blasting results are the same. Inaccurate drilling will change the individual minimum resistance line and hole spacing, blasting results inconsistent. Its impact process
