【摘要】：煤礦開(kāi)采勢(shì)必破壞天然水化學(xué)環(huán)境,然而礦區(qū)多類(lèi)含水層地下水系統(tǒng)水化學(xué)研究尚未從時(shí)空角度分析采動(dòng)影響下水化學(xué)演化的本質(zhì)。以臨渙礦區(qū)為研究示范,基于歷年常規(guī)水化學(xué)數(shù)據(jù)開(kāi)展主成分分析,揭示采動(dòng)影響下水化學(xué)演化過(guò)程中的水-巖作用機(jī)制。其中,第1主成分代表碳酸鹽、硫酸鹽溶解及黃鐵礦氧化作用,第2主成分代表陽(yáng)離子交替吸附及脫硫酸作用。采動(dòng)影響下礦區(qū)主要突水含水層地下水碳酸鹽、硫酸鹽溶解及黃鐵礦氧化作用均逐漸減弱,減弱區(qū)域不盡相同;然而,陽(yáng)離子交替吸附及脫硫酸作用的變化規(guī)律不明顯。研究成果為礦井突水水源識(shí)別和水資源保護(hù)與利用提供理論依據(jù)。
[Abstract]:Coal mining is bound to destroy the chemical environment of natural water. However, the hydrochemistry of groundwater system of many kinds of aquifers in mining area has not been analyzed from the point of view of time and space. Based on the conventional hydrochemical data over the years, principal component analysis (PCA) was carried out in Linhuan mining area to reveal the mechanism of water-rock interaction in the process of hydrochemical evolution affected by mining. Among them, the first principal component represents carbonate, sulfate dissolution and pyrite oxidation, and the second principal component represents cation alternating adsorption and desulfurization. Under the influence of mining, the carbonate of groundwater in main water-inrush aquifer of mining area, sulfate dissolution and pyrite oxidation are gradually weakened, and the weakening regions are different, however, the change law of cationic alternating adsorption and desulphuric acid is not obvious. The research results provide theoretical basis for mine water inrush source identification and water resources protection and utilization.
