由于采矿强度的提高,组成电爆网路的起爆元件数目增加,因而网路的可靠性已,成为重要问题。电爆网路的可靠性是用概率来定义和量度的,并可通过其最小分支来考察。最小分支的可靠度可用数学模型方法求得,称为设计可靠度R_d。实际可靠度R_p除了取决于R_d外,还受网路实施全过程许多偶然因素的影响,用本文给出的简单方法,根据5～10次爆破的实际资料即可确定平均值。由于对不同方案R_p的平均值作比较并考虑经济等因素,因而列它们的可靠性也作出了评价。
Due to the increase of mining intensity, the number of detonating elements that make up the electric burst network has increased, so the reliability of the network has become an important issue. The reliability of an electric burst network is defined and measured by probability and can be examined by its smallest branch. The reliability of the smallest branch can be obtained using the mathematical model method, known as the design reliability R_d. In addition to R_d, the actual reliability R_p is also affected by many accidental factors in the entire process of network implementation. By using the simple method presented in this article, the average value can be determined based on the actual data of 5 to 10 blasting. The reliability of their alternatives has also been evaluated as a result of comparing economic averages with the average values of different programs.
