摘要
随着西石门铁矿深部开采的进行,爆破产生的有害效应在一定范围内影响村民的正常生活。根据西石门铁矿爆破时现场实际情况,计算Vamx、r、s值,确定烈度Ⅰ,评价危险程度。并采取了一系列的技术措施减小影响。
Harmful effect produced by blasting had iniluencd the normal llte of wllager m a certain range with the deep development of Xishimen iron ore. V_amx、,r,s Value was calculated, intensity Ⅰ confirmed, risk level evaluated according to the site situation of Xishimen iron ore blasting and a series of technical measures was adopted to reduce influence.
