龙塘沿铁矿勘查工程间距验证与探讨

龙塘沿铁矿详查采用100 m×100 m的网度探求控制的资源储量，通过近2 a的生产勘探及开拓、采切、回采工程,发现原有勘查工程间距已不能满足矿山开拓和采准工程的布设要求，导致工程及矿量的浪费。为此，通过与详查阶段的对比验证，采用加密法对龙塘沿Fe25矿体的勘探工程间距进行对比，结合规范确定合理的工程勘查间距，采用50 m×50 m的网度探求控制的资源储量。

Verification and Discussion on the Spacing of Longtangyan Iron Mine Exploration Project

The detailed investigation of Longtangyan Iron Mine uses a 100 m×100 m net to explore and control the resource reserves.In the past two years,it has been discovered that the original exploration project spacing can no longer meet the requirements of mine development and mining projects through production exploration and development,mining and cutting,and mining projects.The layout requirements result in waste of engineering and mine volume.Through the comparison and verification with the detailed investigation stage,the density method is used to compare the exploration project spacing of the Longtangyan Fe25 ore body,and another reasonable project investigation spacing is determined in combination with the specifications to explore the resource reserves controlled by a network of 50 m×50 m.
