安全爆破参数的计算在于确定一段延期最大的许用药量、延期段数和延期间隔,以及一次爆破的总炸药量。可按以下顺序计算安全爆破参数。 1.确定瞬发爆破和延期爆破时地震波速度与折算药量的关系。通过试验研究确定了以下关系式:V_(K·3·B)=136ρ~(1·9)·10~(-2);V_(MrH)=270ρ~(1·9)·10~(-2),式中:ρ—折算的药量,ρ=Q~(1/3)r~(-1);Q—炸药量,公斤;r—至爆破中心的距离,米。 2.根据岩石的允许变形确定构筑物等级:例如,在麦卡因、地
The safety blasting parameters are calculated by determining the maximum allowable dose for a delay, the number of delay periods and the delay interval, and the total amount of explosives for a blast. The safety blasting parameters can be calculated in the following order. 1. Determine the instantaneous blasting and detonation blasting seismic velocity and the relationship between the converted dose. Through the experimental study to determine the following relationship: V_ (K · 3 · B) = 136ρ ~ (1 · 9) · 10 -2 V_ (MrH) = 270ρ ~ (1 · 9) · 10 ~ (- 2), where: ρ - converted dose, ρ = Q ~ (1/3) r ~ (-1); Q - the amount of explosives, kg; r- to blasting center distance, m. 2. Determine the level of a structure based on the permissible deformation of the rock: for example, in McCain, ground
