摘要
针对“三小”爆破可以减少药量,提高爆破效果,减少震动等优点,介绍了在煤巷掘进中应用小钻杆、小钻头、小药卷技术所取得的数据,为其它矿区的应用提供了经验。
The blasting technique of'three smallness' has such good qualities as decreasing the amount of power, raising the blasting effectiveness and reducing tremor etc. Based on these qualities. the paper supplies some technical data obtained by applying this blasting technique, namely 'small drill pipe, small bit and small blasting tube', which provides some experience for the application of this technique in other coal mines.
