我国黄金矿山资源危机的现状、成因及潜力分析

China's gold mine resource crisis situation,the origin and potential analysis

我国中东部地区有许多黄金资源量丰富的矿山,由于多年的开采利用,部分矿山保有黄金资源量不足,面临着严重的资源危机。通过对国内124座黄金矿山进行资源潜力调查评估发现,117座矿山存在不同程度的资源危机,其中86座矿山的生产服务年限不足5年,这些危机矿山大多数分布在我国中东部地区。我国黄金矿山数量多,规模小;金矿床储量少,品位低;地质勘探落后,资源利用效率低以及企业找矿机制等原因,造成了危机矿山的出现。即便如此,我国黄金资源仍有很大的潜力,西部地区地质工作程度低,有很多未开发的黄金资源;中东部地区老矿山的深部,尚有未探明的资源有待开发;选冶技术的发展,也将带动资源的二次开发。

In middle and east of China,there are many gold mines with aboundant resources,many of which is facing serious shortage of gold reserves and resources crisis after long-term exploitation.By rescources potential investigating of 124 gold mines in China,there are 117 mines have different degree resources crisis,86 of which have less than 5 years' productive life,and most of them are located in middle and east of China.The appearance of crisis mines is caused by many reasons,such as the large quantity but small scale of gold mineis,poor gold deposit reserves and lower grade,laggard exploration,low utilization rate of resources,and prospecting mechanism of enterprise.Even so,there are great potential of gold rescources in our country.In western China a lot of gold resources are undeveloped for the lower degree of exploration;in middle and eastern China there are unproved resources to be exploited in the deep of old mines.Also the development of ore-dressing and refining technology is driving secendary development of resources.
