露天深孔爆破效果的好与差,主要取决于爆破参数的选择是否正确。本文试从提高炮孔利用率,充分利用炸药爆轰能量,从而使爆破技术经济效益进一步提高出发,用常规确定爆破参数方法:W_d·a→Q的逆过程Q→W_d·a谈谈露天下向深孔爆破参数的确定。任何一次露天深孔爆破,其台阶高度H,炮孔直径D,炸药品种类型在其他爆破参数确 The effect of openhole deep hole blasting is good and bad, mainly depends on the choice of blasting parameters is correct. This article try to improve the utilization rate of blasting holes, make full use of explosive detonation energy, so that the economic benefits of blasting technology to further improve, using conventional methods to determine the blasting parameters: W_d · a → Q inverse process Q → W_d · a talk about the open air Determination of Deep Hole Blasting Parameters. Any one open-air deep-hole blasting, the height of the step H, the diameter of the hole D, the type of explosive in other blasting parameters
