通过对露天矿历年小密集系数爆破及质量分析，结合南露天矿岩石性质，应用大密集系数爆破原理，确定了合理爆破参数及最佳的密集系数。
Through the blasting and mass analysis of the small dense coefficient over the past years of the opencast mine, combined with the rock properties of the southern open-pit mine, the reasonable blasting parameters and the optimal dense coefficient were determined by using the principle of large-dense-coefficient blasting.
