    摘要:

    掌握礦井水特征及功能性利用適宜性是實現礦井水分源處理、分級利用的資源化的前提。以榆樹嶺煤礦為研究對象,采集各類型礦井水進行水樣檢測,劃分礦井水資源化利用類型,建立評價體系綜合分析評價礦井水不同利用方向的功能適宜性。研究表明:礦井水化學類型主要為SO2-4·Cl--Na+型,V類水隸屬度為0.812~0.991,水化學組分含量高,分析存在飲用、灌溉與工業用水三種潛在利用途徑;各類礦井水飲用適宜性評價結果均為Ⅲ級、Ⅳ級,不適宜飲用,在灌溉和工業用水適宜性上,不同類型礦井水評價結果差異較大,采空區積水、裂隙水SAR[3~10.8 (mmol·L-1)1/2]、RSI(6.1~6.5)等指標顯示對土壤理化性質影響較小且基本無腐蝕性,適宜灌溉和工業用水,火燒區積水LSI(0.8~1.2)>0.6,具有結垢傾向,一般不能直接作為灌溉水使用,但能夠用于工業用途,水倉水水質受污染嚴重,SSP(78.4~84.5%)、MHR(62.9~72.0%)、RSI(7.2~7.7)、LR(8.0~12.0)等指標顯示該類型水對土壤堿度及滲透性危害較高,并且具有嚴重腐蝕性,功能性利用潛力較差。

    Abstract:

    To grasp the characteristics and functional utilization suitability of mine water is the premise of realizing the resource treatment and classification utilization of mine water source. Taking Yushuling coal mine as the research object, various types of mine water were collected for water samples detection, the types of mine water resource utilization were divided, and an evaluation system was established to comprehensively analyze and evaluate the functional suitability of different utilization directions of mine water. The study shows that the chemical type of mine water is mainly SO2-4·Cl--Na+ type, the membership degree of V water is 0.812-0.991, and the content of water chemical components is high. There are three potential utilization ways of drinking water, irrigation water and industrial water. The suitability evaluation results of all kinds of mine water are grade Ⅲ and Ⅳ, which are not suitable for drinking. In terms of the suitability of irrigation and industrial water, the evaluation results of different types of mine water are quite different. The gob water, fissure water SAR[3-10.8 (mmol·L-1)1/2], RSI (6.1-6.5) and other indicators show that the impact on soil physical and chemical properties is small and basically non-corrosive, suitable for irrigation and industrial water, the fire area water LSI (0.8-1.2) > 0.6, with a tendency to scale. Generally, it cannot be directly used as irrigation water, but it can be used for industrial purposes. The water quality of the warehouse water is seriously polluted. The SSP (78.4-84.5%), MHR (62.9-72.0%), RSI (7.2-7.7), LR (8.0-12.0) and other indicators show that this type of water has high harm to soil alkalinity and permeability. And it has serious corrosion and poor functional utilization potential.
