摘要
西石门铁矿中二采区与西石门村西片距离较近,最近水平距离仅有190m。中二采区采矿生产爆破作业对西石门村村民的生产、生活造成一定的影响。为了解爆破振动的影响程度,预报爆破振动速度值,在西石门村西片进行了5次爆破振动监测。沿采场至村子的直线方向上从村西到村东布置5个测点,共测得18组有效数据,拟合出西石门村西片区域爆破振动速度预测公式。理论校验分析和实验证明该公式是合理的。
The No. 2 middle mining area of Xishimen iron mine is very near to the west of Xishimen vil- lage. The nearest horizontal distance is only 190m. Then, the villagers were disturbed by mining blasting of No. 2 middle mining area. In order to know the impact degree of blasting vibration and to predict the blasting vibration velocity, it was monitored for 5 times at the west of Xishimen village. From the west to the east at the west of Xishimen village, along a straight line between the blasting points and the village, 5 measuring points were laid up on the ground. A formula was fitted out to predicting the blasting vibration velocity at the west of Xishimen village based on 18 group valid measured data. The formula was turned out to be reasonable by the results of experiments and check analysis.
