回顾了黑火药开创工程爆破的历史贡献,列举了工程爆破对保留岩体或围岩的破坏和损伤实例,评价了原有光面爆破预裂爆破等定向断裂控制优缺点。发明了定向卸压隔振爆破。由于此两种爆破方法的基本原理、应用范围和目的相同,可构成“工程控制爆破”的另一种爆破类型,它专门用于轮廓线炮孔爆破,使保留岩体避免破坏;减轻损伤和采矿分采爆破,降低贫化损失。对两种方法进行了特征比较和效果评价,列出了后一种方法的效果图片。
Reviewing the historical contribution of black gunpowder to engineering blasting, enumerating the examples of damage and damage caused by blasting on retained rock mass or surrounding rock, and evaluating the advantages and disadvantages of directional fracture control such as pre-cracking blasting of original smooth blasting. Invented directional relief vibration isolation blasting. Since the two blasting methods have the same basic principle, application scope and purpose, they can constitute another type of blasting of “controlled blasting”, which is devoted to the contour blasting of the blasthole so as to avoid the destruction of the reserved rock mass; to reduce Damage and mining sub-mining blasting to reduce depletion losses. The two methods have been compared with the characteristics of the results and evaluation, the effect of the latter method is listed.
