针对神东矿区水质复杂以及不同矿井水质差别较大的问题,对40个矿井水质硬度、p H值、硫酸根、氯离子等进行了测试分析,并分别研究了矿井水质和人工水质的总硬度、硫酸根离子、氯离子浓度对3种乳化液产品稳定性的影响。结果表明:矿井水总硬度和硫酸根离子浓度过高均会对乳化液稳定性产生不利影响,人工水总硬度达到700 mg/L,或硫酸根离子浓度达到1 000 mg/L,将导致乳化液稳定性不合格;氯离子浓度在不高于400 mg/L时,对乳化液稳定性影响较小。该研究结果可为神东各矿井合理选择乳化液提供技术支持。

According to the complicated water quality in Shendong Mining Area and big water quality difference problem in different mines, a test analysis was cond ucted on the water hardness, p H value, sulfate, chloride ion and others of 40 mine waters and individually discussed and study the total hardness, sulfate ion and chlor ide ion concentration of the mine water quality and artificial water quality affected to the stability of three type emulsion products. The discussion and study results show ed that the too higher total harness and sulfate ion concentration of the mine water all would have unfavorable influences to the stability of the emulsion. When the total hardness of the artificial water quality reached at 700 mg/L or the sulfate ion concentration reached at 1 000 mg/L, both would cause the stability unqualified of the emu Ision. When the chloride ion concentration was not over 400 mg/L, a less influence would be caused to the stability of the emulsion. The study results would provide the technical support to the rational selection of the emulsion for each mine in Shendong Area.
