摘要
生产勘探是矿山生产中必不可少的一项前期工作,它是对之前地质勘探资料的修正和补充。通过生产勘探可以更进一步控制矿体的形态、分布和规模,对之后的矿山采矿生产起到重要的指导作用。目前井下钻探工程是生产勘探十分重要的手段,应用十分普遍,具有有效率高、成果准、成本低的优点。介绍了井下钻探工程在北京密云沙厂铁矿的实际应用,通过对Ⅱ矿带-16 m、Ⅲ矿带14 m、Ⅱ矿带-1 m三个地段的井下钻探技术布设,对报告原矿体进行了验证控制、对矿山开采储量进行了修正,为以后采矿工程的调整与布置提供了可靠的地质资料及地质依据。
Production exploration is an indispensable preliminary work in mine production,it is the revision and supplement of previous geological exploration data.Through production exploration,the shape,distribution and scale of ore body can be further controlled,which plays an important guiding role in the subsequent mining production.At present,downhole drilling engineering is a very important means of production exploration,which is widely used,with the advantages of high efficiency,accurate results and low cost.This paper introduces the practical application of underground drilling technology in Beijing Miyun Shachang iron mine,through the layout of underground drilling engineering in three sections of"ore zone II-16 m,ore zone III-14 m and ore zone-1 m",the original ore body is verified and controlled,and the mining reserves are verified and controlled.The results and positive effects of downhole drilling engineering are analyzed.
