一、前言毫秒爆破是近代爆破工程上的一项新技术,最初开始用于露天爆破,目的在于改善爆破效果和减轻地面震动。后来鉴于它有许多优点,才逐渐扩展到煤矿中。煤矿应用毫秒爆破,首先是为了提高效率缩短放炮时间,改善工人劳动条件,同时在予防瓦
I. INTRODUCTION The millisecond blasting is a new technology in modern blasting engineering and was initially used in opencast blasting with the aim of improving the blasting effect and alleviating ground vibration. Later, given its many advantages, it gradually expanded into coal mines. Millisecond blasting application of coal mines, the first is to improve the efficiency of shortening the shooting time, improve working conditions of workers, at the same time to prevent tile
