老挝万乔钾盐矿开采技术条件分析

Analysis of mining conditions of Wanqiao sylvite deposit,Laos

文章通过对矿区含、隔水层的划分及补给、径流、排泄条件的分析,确定了该矿区水文地质条件;根据岩石质量等级和顶底板围岩稳定性评价,对矿区的工程地质条件进行了分析,提出了矿区开采后可能产生的工程地质问题;调查了矿区内环境地质现状,并对矿区因开采而造成的环境影响进行了预测。基本明确了矿床开采技术条件属于中等类型,为矿区的建设和开采提供了参考依据。

Based on the division of aquifer and aquiclude and analysis of the conditions of recharge, runoff, drainage, the paper discusses how to determine the hydrogeological conditions in the mining area. According to the quality grade of the rock and the stability of the roof and floor strata, the paper tanalyzes the engineering geological conditions of the mining area and put forward the engineering geological problems may occur after mining. Futher more, the geological environment condition has been investigated and the impact on enviroment caused by mining has been predicted in this paper. It is generally clear that the mining technical conditions belong to the moderate type, which is a reference for the mine construction and mining.
