基于3DMine软件的采空区隐患资源储量估算

Estimation of hidden resource reserves based on 3DMine software

采空区错综复杂导致其隐患资源储量难以确定,本文借助3DMine软件介绍多种矿床资源储量估算方法在湖北某铜矿山采空区隐患资源量评价中的应用,包括地表、矿体、采空区等三维地质模型的建立;典型矿区变异函数的计算和模型拟合;利用最近距离法、距离幂次反比法和普通克里格法逐步优化矿床储量估算和采空区消耗资源量类别的自动化划分,进而实现普通克里格法估算复杂采空区群隐患资源量,为矿山企业制定下一步生产计划和评估隐患资源开采经济效益提供重要的理论依据。

The complexity of goaf leads to the difficulty of determining the reserves of peripheral residual resources.This paper introduces the application of 3DMine software to evaluate the potential resource of several copper deposits in a copper mined area in Hubei province,including the establishment of three-dimensional geological models such as surface,ore body and goaf;the variation function of typical mines Calculation and model fitting;using the nearest distance method,distance power inverse ratio method and the ordinary Kriging methods for automatic classification of ore body and goaf resource types and resource estimation,so as to realize the hidden resources of complex goafs estimated,it provides important theoretical basis for mining enterprises to make next step production plan and evaluate the economic benefit of hidden resource exploitation.
