地质编录数据的三维处理方法在生产中的应用
|
摘要
矿区位于中生代陆相火山盆地边缘的古隆起部位,次一级断裂构造十分发育,断层两侧被晚期不含矿流纹斑岩及安山玢岩脉填充,对矿体起破坏作用,对铜矿体的完整性有很大影响。利用地质编录三维处理方法,真实展现矿体、构造在空间上的对应关系,块体估值过程中对侵入非矿岩体进行剔除处理,使估值结果及矿体边界线更真实,接近矿体实际,达到了提高采剥计划、采矿单体设计执行率及降低损失贫化率的目的。
The ore area is located in the palaeohigh of margin of Mesozoic continental volcanic basin.The sublevel fault structure is very developed.The both sides of the faults are selled with the rhyolite porphyry and the andesite porphyry,which has a destructive effect on the orebody and affecting orebody integrity.Based on the threedimensional processing method to geologic log,the truly spatial correspondence between orebody and the geologic feature were shown.The infracrustal rock was exculed,which is unmineralized rock,so that the valuation results and ore boundary were more realistic,close to the orebody,further to improve the stripping plan execution rate,mining unit design execution rate and reducing the loss rate and delete rate.
