实现最佳爆破设计的常用方法是试验确定法。本文讨论的方法是如何用两个现场试验的单孔爆破结果,实现最佳的爆破条件。使用的方法是逐次加大抵抗线,每次只爆一个孔,所有单孔爆破后都形成一个三棱形台阶漏斗。不同抵抗线的炮孔爆破后,记录破碎角、后冲和最大破碎块度。然后根据单孔爆破结果设计最佳的生产爆破。 A common method of achieving the best blast design is the test determination method. The method discussed in this paper is how to achieve the best blasting conditions using the results of two single-hole tests in the field. The method used is to increase the resistance line one by one, blasting only one hole at a time, forming a triangular prism funnel after all single-hole blasting. After blasting the blasting holes with different resistance lines, the broken angle, the backlash and the maximum crushing degree were recorded. Then according to the results of single-hole blasting design the best production blasting.
