龙滩电站兴建对烂泥沟金矿影响评价

An Appraisal of Effect Produced by Building the Longtan Power Station on Lannigou Au Deposit

烂泥沟金矿为贵州省大型金矿之一,为了查明龙滩电站修建水库回水对其淹、浸没损失,通过大量工作,勘探试验和分析研究,在查清矿区水文地质条件的基础上,对水库回水后对矿区的影响程度作出了较客观的评价。

Lannigou Au Deposit is one of the largest Au deposits in Guizhou Province. In order to make clear the losses caused by flooding and immersing after building a reservoir at the Longtan Power Station to regain water, through a lot of work like prospecting tests and analysis researches and on the basis of ascertaining the hydrogeological conditions of the ore area, this paper has made a more objective appraisal of the effect produced by the reservoir's regaining water on the ore area. The writer has widely collected opinions of some leaders and experts concerned from Central South China Prospecting and Designing Institute, and Planning Commission, Reserves Commission and Au Administrative Bureau of Guizhou, as well as Guizhou Bureau of Geology and Minerals, with identical views held that the data used to make the appraisal are abundant and practical, and the conclusion is clear, with enough scientific evidence. Therefore, the appraisal is reliable and can be used as one of the bases in designing the Longtan Power Station.
