小型硐室崩塌爆破采矿

摘要

The experiences in mining by once-through chamber blasting in a steep geography condition are introduced.The reasonable cartridge layout and dose are selected to match the special geographical and geological conditions,the program meets the requirements of both production and safety of further mining.%介绍了在陡崖地形条件下的一次硐室爆破采矿的实践经验，针对长、高、窄岩壁的特殊地形和地质条件，选择适宜的药包布置形式和装药量，既满足了生产需要，又保证了下一步开采的安全。
