通过对工作面水质进行化验总结,运用AquaChem软件绘制Piper三线图,对7199工作面4个月的水质进行统计分析,结果表明:7199工作面突水水源中包含顶板砂岩水、分界砂岩水、第四系底含水和侏罗白垩水。为更准确地确定突水水源间的主次关系,以模糊数学为基础,结合矿井含水层水化学分析资料,利用模糊综合评判法建立了矿井突水水源判别模型,选取6种常规离子作为判别因子,最终得出7199工作面直接出水水源为顶板砂岩水和下石盒子组底界砂岩水,并存在第四系底含和侏罗白垩水的间接补给。
By analyzing the water quality of the working face and using the AquaChem software to draw the Piper third line diagram, the water quality of the 7199 working face for 4 months was statistically analyzed. The results showed that the water inrush of 7199 working face included roof sandstone water and boundary sandstone water. Quaternary aquifer and Jurassic chalk water. In order to more accurately determine the primary and secondary relationships between water inrush sources, based on fuzzy mathematics, combined with the chemical analysis of aquifer water samples, a fuzzy comprehensive evaluation method was used to establish the water inrush source discriminant model. Six kinds of conventional ions were selected as discriminant Factor, the final water source for 7199 working face is roof sandstone water and sandstone water at the bottom of the Lower Shihezi Formation, and there is an indirect recharge of Quaternary sediments and Jurassic chalk water.
