【摘要】 从地质勘探评价到矿床开采的整个工作过程,各个阶段都需要根据不同任务的要求,对矿床进行多次储量计算,因此,储量计算一直被列为固体矿产资源地质勘探各阶段极其重要的工作。SD法诞生于上世纪八十年代,它通过对传统法和样条函数法的改进以及与地质统计学法和距离幂次反比法等方法的结合使其在储量估算领域内具有一定的先进性。SD法引出了结构地质变量概念、搜索递进计算法以及极限精度法——SD精度法。从而实现SD动态审定一体化储量计算,使得SD法能根据地质工作阶段划分的要求,正确掌握取样的有限性,确定工程控制程度。本文以西藏自治区墨竹工卡县甲玛铜多金属矿区的资源量估算课题为背景,通过对各种储量计算方法的研究,最终选定SD法作为储量计算工具来计算矿区资源量。在此基础上,还对甲玛矿区的矿石品位关系以及三维解释方面做了相关研究。本文的详细研究内容如下:1详细研究国内外相关储量计算方法;2探讨SD法的理论基础及计算方案;3根据甲玛矿区实际情况制定详细的计算方案;4基于SD法和平行断面法估算甲玛矿区资源量,并对估算结果做对比分析;5研究矿石品位关系,并做相关分析;6基于ArcGIS完成甲玛矿区的三维解释。更多还原

【Abstract】 During the whole working process of geological exploration and deposit mining, reserve calculation need to be practiced many times to meet the requirements of different stages. Thus, reserves calculation is regarded as an extremely important process in each stage of geological prospecting of solid mineral resources.SD method was born in the 1980’s, it has advancement in the field of reserves calculation due to its combining geostatistics with distance power inverse ratio method and the improvement of traditional method and spline function method. The concept of structure geological variable, the method of progressive searching and the method of limit precision-SD precision method was given. Therefore, SD method can correctly grasp the limitation of sampling and determine the control degree of the project according the stage of geological working.This paper is based on the reserves calculation subject of Jiama mining area. The SD method is chose as a tool to calculate the resource extent after a thorough study of various kinds of calculation method. On this basis, the relationship of ore grade and 3-dimensional interpretation of Jiama mining area was analyzed. The main research contents of this paper are as follows:1. The relative reserve calculation methods at home and abroad were studied carefully;2. The theoretical foundation and calculation scheme of SD method were discussed;3. A detailed calculation scheme of SD method was made;4. The resource extent of Jiama mining area was estimated by SD method and traditional section method and the estimation resu??were analyzed;5. The relationship of ore grade was analyzed and the relative analysis was taken ;6. The 3-dimensional interpretation of Jiama mining area has been given through ArcGIS.更多还原
