众所周知,在爆破腔的形成中清楚地表明了介质的强度特性,而爆破腔的大小则是最简单的可测参数。利用最小抵抗线对爆破漏斗几何参数的影响规律,可以获得实际用于最优凿岩爆破参数计算的关系式。为此,在石英、绿泥石、锡石组成的树 It is well known that the strength characteristics of the medium are clearly demonstrated in the formation of the blasting cavity, whereas the size of the blasting cavity is the simplest measurable parameter. By using the rule of least resistance line on the geometrical parameters of the blasting funnel, the relation between the actual calculating parameters and the parameters of the optimal blasting can be obtained. For this purpose, trees composed of quartz, chlorite and cassiterite
