光面爆破不耦合系数的初步研究

The Preliminary Study on Decoupling Coefficient of Smooth Blasting

以绝热方程为基础,推导出不耦合系数的计算式,将该计算式应用于工程实例计算,得到该计算式下轴向不耦合系数的取值范围,并根据工程实例计算不同径向不耦合系数取值下的轴向不耦合系数,绘制了两系数的关系曲线图,为类似工程不耦合系数取值提供参考。

As a profile control blasting technology, smooth blasting is widely used in conservancy engineering construction. The di- ameter of holes, the distance between them, the density of explosive filling medicine and the decoupling coefficient are the important factors affecting blasting quality. Based on the adiabatic equation, the formulas of decoupling coefficient are deduced and practised in typical engineering to obtain the value range of axial decoupling coefficient, and the axial decoupling coefficient under different radial decoupling coefficient is calculated. A curve indicating the relationship between the two coefficients is drawn to give reference for the value of them in similar projects.
