摘要
针对兰尖铁矿采矿生产距主要平硐溜井近、边坡高度高 ,爆破对这些设施影响大的问题 ,开展了爆破降震技术研究 ,实施了孔间微差爆破减震技术 ,通过计算及试验 ,研究了合理的孔间微差参数、孔网参数 ,结果表明 ,采用孔间微差爆破在降低爆破震动、保护平硐溜井安全稳定方面效果明显 ,是一种简便、易行、可靠的降震方法。
In view of the problems such as the short distance between the mining production site and the main drift pass, high slope and great effect of blast on these facilities, investigation of blast induced vibration reducing technology was made and vibration technology of between holes short delay blasting executed. Rational between holes short delay parameters and hole pattern parameters were studied through calculation and test. The results showed that between holes short delay blast could have evident effect on reducing blast induced vibration and protecting the safety and stability of drift pass, being proved to be a simple, easy to operate and reliable method for vibration reduction.
