摘要
林西矿开采历史悠久,由于采动破坏,各含水层之间的水力联系较为密切,矿井水文地质条件变得更加复杂。根据林西矿的水文地质资料、矿井主要含水层水样测验资料以及相关地球化学数据,各充水含水层水样的水化学特征相似度比较高,较难区分开来。为及时分析、判断矿井生产过程中突水水源,需要分析林西煤矿水质特征,确定地下水水质特征离子。以贝叶斯判别模型构建矿井水源识别模型,建立含水层水质特征数据库,实现快速、准确的分析判断矿井突水水源,为治理水害提供依据,确保矿井水害防治工作高效进行。
Linxi mine with a long mining history,and the hydrogeological conditions of the mine become more complex due to the close hydraulic connection between the water-bearing layers as a result of mining damage.According to the hydrogeological data of Linxi Mine,water sample test data of the main aquifers of the mine and relevant geochemical data,the water chemical characteristics of water samples of each water-filled aquifer were relatively similar and difficult to distinguish from each other.In order to timely analyze and judge the source of sudden water in the mine production process,it is necessary to analyze the water quality characteristics of Linxi Mine and determine the characteristic ions of groundwater quality.The Bayesian discriminant model was used to construct a mine water source identification model and establish a database of aquifer water quality characteristics to achieve rapid and accurate analysis and judgment of mine sudden water sources,providing a basis for managing water damage and ensuring efficient mine water damage prevention and control.
