层内爆炸压裂岩石破碎颗粒尺寸的预测模型
A size prediction model for rock particles generated by an explosion in fractured rock
摘要
Abstract
According to the blasting experiences and actual explosion-in-rock induced rock fragmentation, the shock wave energy produced by the liquid explosive explosion was separated into the surface energy of the fractured rock and the strain energy in the rock by applying the energy conservation law. And based on the rock fracture mechanics principle, a model was proposed to predicate the fragmented rock particle sizes in the cracked region. A calculation example was given in which the diameter of the fragmented rock particles was 1. 43 mm. The calculated results display that the diameter of the fragmented rock particle generated by the liquid explosive explosion in rock is equivalent to that of the hydraulic fracturing proppant particle in the oil industry.关键词
