摘　　要：推断资源量是指经稀疏工程圈定而估算的资源量或高级别资源量外推部分,其地质可靠程度较低。中国现阶段地质勘查成果中推断资源量所占比例通常在50%左右,在矿山开发设计过程中,合理利用该部分资源,是确定合理可采范围、可采资源量及矿床开发评价的基础。以马滴达北山金铜矿床为例,从资源的可采性、开采的经济合理性、工程的控制程度等方面分析其可利用性,并依据该矿床地质勘探成果,进行地质可靠性分析,确定资源利用系数,最终确定可利用推断资源量。从多个角度对推断资源量的可利用性进行综合分析的目的是为矿床开发评价提供较可靠的地质依据,从而较为真实地反映项目未来开发可行性的评价结论。Inferred resources refer to the resources estimated and delineated by coarse projects or the extended part of high-level resources,whose geological reliability is poor.In current geological prospecting achievements of China,inferred resources account for around 50%.In the design and development of mines,reasonable utilization of these resources is the basis to determine reasonable minable scope,minable resources and deposit development evaluation.In the case study of Madidabeishan Gold Copper Deposit,the availability can be analyzed in terms of the workability of the resources,economic reasonability of development and management degree of the project.And based on the geological prospecting achievements of the deposit,the geological reliability is analyzed,the resources utilization coefficient is determined,and the available inferred resources are finally determined.The goal of comprehensive analysis of the availability of inferred resources from multiple aspects is to provide solid geological basis for deposit development eva-luation,so that the feasibility of future projects is reflected in a realistic way.
