水化学综合识别模式在矿井水源判别中的应用

 随着煤炭资源开采逐步向下延伸，面临的矿井充水条件逐渐复杂。下组煤开采面临的突水水源有上部老空水、第四系松散层水、地表水、顶板砂岩裂隙水和深部奥灰水；在复杂构造条件的影响下，井下涌水出现异常，但目标充水水源水位监测数据未发生明显变化，此时准确判别井下涌水的主要充水水源对矿井防治水至关重要。通过应用实例的分析，证明以常规水化学聚类分析和环境同位素分析构成的水化学综合识别模式对复杂条件下矿井充水水源的判别成效明显，为预防矿井突水事故、保障安全生产提供重要依据。

Application of Hydrochemistry Comprehensive Identification Mode to Distinguish Mine Water Resources

With coal mining gradually downward, water-filled conditions became more complex during mining. Water-bursting sources of lower coal group include upper golf water , Quaternary aquifer, surface water, sandstone crack groundwater and deep Ordovician aquifer.Under the condition of complex constitution, mine groundwater inflow occur unusual, but water level monitoring data of target aquifer did not change significantly, then accurately determining main water source of mine gushing water is essential for mine water prevention and control. By analysis of examples application, it is proved that integrated identification model of hydro-chemical characteristics consisted of conventional hydrochemical cluster analysis and environmental isotope analysis under complex conditions is effective obviously to discriminate water source of coal mine, and can provide important basis for mine water bursting accidents prevention and safety production.
