摘要
随着开采规模的扩大,狮子山最大单响药量也在增加,爆破产生的地震效应也在增强,严重威胁井下巷道及构筑物的安全。为了降低爆源周围爆破振动危害,对狮子山十六中段的生产爆破进行爆破振动监测,运用萨道夫斯基公式进行线性回归计算,确定十六中段同一水平、不同水平、西飘带矿萨道夫斯基中的衰减系数和衰减指数。
The maximum explosive charge of each blasting in Shizishan mine is increased along with the expansion of mining scale, the seismic effect of blasting is also strengthened, which seriously threatens the safety of underworkings and structures. In order to re- duce the blasting vibration around the blasting source, the blasting vibration monitoring was carried out on production site of the 16th middle section, Shizishan mine; the linear regression calculation is performed by using of the Sadowski formula, which is used for determination of the attenuation coefficient and attenuation index in Sadowski formula in west ＂floating＂ ore belt with the same level or the different levels of the 16th middle section.
