大姚六苴铜矿床“小河—石门坎”矿段成矿预测及探矿方案
|
摘要
铜是仅次于铁和铝之后居第三位的重要金属。我国铜消耗量大,供应短缺,长期依赖进口的局面很难改变。但我国许多金属矿山已开采数十年甚至上百年,探明保有资源储量濒临枯竭,急需开展老矿区深部及外围地区接替资源找矿研究。为此,2005年国家开展全国危机矿山接替资源找矿试点工作,全国共筛选了九个试点项目,“云南省大姚县六苴铜矿小河—石门坎矿段接替资源找矿”即为试点项目之一,旨在增加资源储量,延长矿山服务年限,促进地方经济社会发展。
滇中楚雄盆地是我国砂(页)岩型铜矿的主要矿化集中区,大姚六苴铜矿是砂岩型铜矿的典型矿床之一。本文全面阐述了区域地质、矿区地质及矿床(体)地质特征,认真分析了矿区地质勘探、地质科研等工作的许多资料,通过地球化学原生晕和EH-4测量,结合矿山生产和探矿的实际情况,指出了六苴矿床南部(深部)“小河-石门坎”矿段是最佳找矿靶区。进而提出采用井下坑探加坑内钻探的探矿方案和工程布置形式,预测了铜资源量(333+334金属量约15万吨),对开展老矿山深部和近外围找矿以及矿山持续接替具有重要意义。
Copper is a wide used and important metal, which is secondly to iron and aluminum. Because of the China's copper consumption, and supply shortages, the situation of long-term dependence on import is very difficultly change in the future. Copper consumption in China in 2002 for the first time the United States, has been the highest in the world for seven consecutive years. Domestic copper consumption in 2006 is up to 4,390,000 tons. Of which: domestic produced 1.43 million tons of copper (750,000 tons was produced, recycling 680,000 tons of waste copper), self-sufficiency rate of only 33%. Imported 2.96 million tons of copper (830,000 tons of refined copper, copper concentrate,1.13 million tons,1,000,000 tons of waste copper).Metal mines in China has been the exploitation of many decades or even centuries, proved reserves to maintain the verge of depletion of resources. Countries in 2005 to replace the national crisis resource exploration mining pilot screening a total of nine national pilot project, "Xiaohe-Shimenkan mineral resources of Luju Copper mine in Dayao county, Yunnan Province prospecting succeeding paragraph," is one of the pilot project, aiming to carry out the old deep mines and prospecting with the external current and long-term economic and social significance.
The Chuxiong Basin is the main sandstone copper mineralization concentration area in China, and the Liuju copper deposit is one of the typical sandstone copper deposits in this basin. Based on features of regional geology, mine geology and deposit geology, the paper analyzes the datum of geological exploration and geological scientific research. Combined with the mining production and prospecting, and the results of the geochemistry applicing and the EH-4 measureing, it points out that the Xiaohe-Shimenkan ore block which located in the south and depth of Liuju copper deposit is the favorable segment for prospecting. The prospecting scheme of pitting and drilling is given in the paper. The inferred resources (333) and predicted resources (334) of total copper resource estimation are 0.15 million tons. It has important significance for enlarging the replacement resources, and metallogenic prognosis prospecting of the old mine in the depth portion and the periphery area.
