Research and Application of Water-decouple Charge's Influence on Fracture Range of Rock Blasting

摘要

This paper is based on explosive detonate theory, water-explosion theory and elastic wave theory, influence of water-decouple charge on blasting energy usage, primary shock pressure of hole and dynamic stress distribution in rock was analyses and studies; and rock fracture area arouno the hole which was based on strength theory was calculated. Set design of cut hole dispose parameter as a engineering example, according to calculation result from radius theory of fracture area around rock of some vertical well digging blasting, feasible of rock fracture area theoretical analysis was further proved from engineering application side.
