摘要
针对冬瓜山铜矿千米深井矿床矿体和围岩的力学特性和地质特征,对深部开采光面爆破技术进行了现场试验研究。详细介绍了开拓中光面爆破的参数选择、施工方法及工艺。试验表明,本文的爆破技术能够起到良好的爆破效果,对控制巷道的稳定性和超欠挖能够起到积极的作用。
According to the mechanical properties and geological features of the 1000-meter deep deposit and surrounding rock in Dongguashan Copper Mine, smooth blasting technology in deep mining is studied by field test. Smooth blasting parameter selection, construction method and technology in the development are introduced in details. The test showed that smooth blasting technology had a good blasting effect and could play an active role in the controls of roadway stability and overbreakunderbreak.
