摘要
针对某矿三水平皮带下山岩爆的特点,提出采用爆破卸压的方法预防岩爆,并采用数值模拟的方法优选了延伸辅助眼浅孔爆破卸压方案。工程实践、电磁辐射监测表明延伸辅助眼浅孔爆破卸压方法是一种经济、合理、有效防治岩爆的方法,值得在类似的工程中推广。
According to the characteristic of the rock burst in third horizon belt dip-head in a certain coal mine, the idea of preventing the rock burst by relieving shot was put forward, and the scheme of the shallow hole with extending the secondary blasting hole was selected through numerical simulation. Engineering practice and electromagnetic radiation monitoring show that the way of extending the secondary blasting hole is a reasonable, economical and efficacious method to prevent the rock burst, and is worth to be used in similar projects.
