国内外煤炭资源量报告对比研究——以南澳WINTINNA矿区为例

Comparative Study of Domestic and External Coal Resource Reports——A Case Study of Wintinna Exploration Area, South Australia

以南澳州WINTINNA煤炭勘查区为实例,选取以我国《固体矿产资源储量分类GB/T 17766-1999》标准为勘查标准的《南澳WINTINNA勘查区详查地质报告》和以《澳大利亚矿产资源和矿石储量公布规范(JORC规范)2004》为标准的《WINTINNA煤炭资源量评述报告》作为对照,从报告结构、矿产资源量估算、煤炭资源量结果、资源量变化原因四个方面进行了详尽的对比研究,通过算理与算法对资源量变化原因进行剖析,深入阐述了以JORC标准为主导的国际资源储量估算领域的指导思想和国际通行估算方法,指出了国内外在煤炭资源储量估算领域的不同,对提高我国的资源储量报告在国外市场上的效力、实现国内外主要资源储量标准分类下该类型资源储量报告的快速准确映射和转换具有实际意义。

Taking the Wintinna exploration area in South Australia as an example, contrasted 〈South Australia Wintinna Exploration Area General Exploration Geological Report, April 2011〉 based on the 〈Classification for Resources/Reserves of Solid Fuels and Min- eral Commodities GB/T 17766-1999〉, and 〈Statement of Coal Resources Wintinna〉 based on 〈The Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves （The JORC Code） 2004〉 carried out detailed comparative study from four aspects of report structure, mineral resources estimation, coal resources estimated results and causes of resources differences. Through estimation theory and algorithm carried out causation analysis of differences. Detailed expounded external resource and reserve estima- tion guiding ideology and prevailing methods dominated by the JORC code, pointed out the differences between domestic and external coal resource and reserve estimations. The study has practical significance to promote potency of our resource and reserve reports in ex- ternal markets, realize fast and accurate representation and conversion of such typed resource and reserve reports under major resource and reserve standards.
