四、底盤抵抗线的设计合理的抵抗线决定中爆破效果与成本,是中爆破孔设计工作中,最为重要的一环,特别是在L.O.X爆破上,更具有重要的意义。阿索诺夫所著的爆破工程,设计中爆破孔W的公式为:W=HPn………………(15)~(++)式中:W——底盤抵抗线,公尺P——系数主要是根据岩石硬度来决定的。硬岩上P值应该小些,以免留下根底及减少大块矿石。软岩上P值应该大些,以增加每孔的爆破量,如第四表n——系数根据阶段高来决定,如第五表。
Fourth, the design of the chassis resistance line Blasting effect and cost of a reasonable resistance line decision is the most important part in the blasting hole design work, especially in L.O.X blasting, more important. Asonov’s blasting project, the design of blasthole W formula is: W = HPn .................. (15) ~ (++) Where: W - chassis resistance line, the meter P- - The coefficients are mainly determined by the hardness of the rock. P value should be smaller on hard rock, so as not to leave the foundation and reduce the large ore. Soft rock P value should be larger, in order to increase the amount of each hole blasting, such as the fourth table n - coefficient according to the stage to decide, such as the fifth table.
