The mechanism of directional fracture controlled blasting and its application |
| abstract |
Synthetically using methods including high speed laser tattoo shadow, super dynamic strain testing technology, digital laser dynamic caustics experimental system, this paper studies the cutting seam cartridge explosion wave propagation mechanism, multi-angle observation of the detonation wave propagation process, clearly observed explosion stress wave and explosive gas separating phenomenon.Air interval cutting seam cartridge blasting cement mortar model testing was carried out.The spatial distribution law of stress was summarized.The cutting seam cartridge decoupling blasting explosive raw crack dynamic fracture effect was analyzed.The different charge structures influence on critical raw crack extension was compared.The best decoupling coefficient is 1.67 with directional fracture controlled blasting effect was determined.It studied double hole grooving method, initiation at the same time, through the crack between the two hole and the hole of the lateral dynamic behavior of crack propagation.Finally the cutting seam cartridge directional fracture controlled blasting technology was applied in shaft and tunnel blasting construction.The directional fracture of cutting seam cartridge blasting effect was verified.This research will provide experimental basis and theoretical guidance for engineering practice. |
