摘要
文章论述在斜井掘进中采用定向控制爆破技术 ,利用最小抵抗线原理 ,即最小抵抗线方向是爆破作用和岩石移动的主导方向 ,使石渣向后抛掷 ,以充分利用耙斗装岩机工作 ,从而大大提高工作效率 ,降低工人的劳动强度。
During driving of inclined shaft, in order to coordinate the rake-loader to load rock, the directional control blasting technology was adopted. It can make full use of the theory of minimum resist line, which means the direction of minimum resist line is the leading direction of blasting and rock movement, so that the rocks were thrown backward and easily loaded by rake-loader, that make highly improve efficiency and lower the labor intensity possible.
