摘要: 高矿化度矿井水的排放影响着矿区周边生态环境,为提高高矿化度矿井水的利用量,降低对环境的风险,介绍了九龙矿基于国内高矿化度矿井水处理利用技术现状,选择将高矿化度矿井水深度处理后,回用于井下生产和回灌井下含水层,实现高矿化度矿井水的零排放的案例。以该矿地下水水质为基础,结合《地下水质量标准》(GB/T 14848—2017)中Ⅲ类水质要求,确定该矿高矿化度矿井水井下循环利用水质指标,指导深度处理工艺选择,促进煤矿向绿色矿山、绿色生产方式的转变,为其他同类矿山提供借鉴。

Abstract: Highly-mineralized mine water discharge influenced the ecological?environment around?the?coal mine?area, based on the current situation of highly-mineralized mine water treatment and utilization technology, the?coal mine?area chose highly-mineralized mine water after advanced treatment was recycled on the production process and was back-filled underground coal to realize zero discharge of highly-mineralized mine water. Based on the groundwater quality of the coal mine and class III water quality requirements in Standard for Groundwater Quality (GB/T14848-2017), the paper proposed index of back-filling water quality to guide the selection of advanced treatment process, promoted the transformation of coal mines into green mines and green production modes, and provided reference for other similar coal mines.
