摘　　要：根据机场对填方石料粒径的严格要求及石料场周围的复杂环境。我司技术人员根据多年 ,多次硐室大爆破成功的经验 ,从导洞布置方面严格要求各药室最小抵抗线均一化 ,从药包布置、药量分布、装药结构、起爆顺序等方面作了许多科学改进 ,精心设计 ,严密施工。For the stern requirement that more than 90% of the stone fill must have a diameter less than 40cm and the complicate stratigraphic condition of the Hanwushan Mt.stone fill field.according to the successful experiences for many years in chamber blasting,skilled staff of our company made plenty of scientific improvements.we designed operated meticulously and achieved complete success in 'standard controlled chamber blasting'.It is expected that this paper can summerize some experience for similar engineering in the future.

关 键 词：硐室控爆 石块粒径 最小抵抗线 毫秒微差爆破机场 爆炸参数
