复杂环境下控制抛掷硐室大爆破

摘要

通过工程实践，在复杂环境下精心布药、合理分段，采用南抛北松硐室大爆破，克服抛掷爆破中飞石、溜渣危害与防护相矛盾的难题，达到控制飞石、溜碴、抛掷与安全防护的要求。%In complicated environment, reasonable cartridge layout and sublevel and the "south-throwing north-loosing" chamber blasting were adopted in the practice to solve the difficult problems of flyrock and remained debris, the design meets the requirements above.
