通过模拟爆破试验,在五种不同延迟间隔时间中寻求合理的微差爆破时间,据此进行工业试验。结果证明,所采用的50ms间隔时间可以改善破碎效果,减少抛掷距离,明显提高岩巷掘进效益。
By simulating the blasting test, a reasonable micromolt time is sought for five different delay intervals and an industrial test is conducted accordingly. The results show that the 50ms interval used can improve the crushing effect, reduce the throw distance, significantly improve the rock tunneling benefits.
