矿井水井下-地面分级分质高效利用与智能调配技术

Efficient utilization and intelligent allocation technology of mine water based on underground-surface and classification and quality

针对目前矿井水处理后回用成本高、时空分配不均和循环利用率低等问题,通过矿井水水量平衡和回用水质数据分析,探究了大海则矿区矿井水量质耦合变化规律,采用大数据计算和嵌入式系统设计,形成了矿区矿井水井下-地面高效利用途径和智能调配技术。结果表明:大海则矿区原矿井水就地利用率低,仅为矿井总排水量的22.1%,水质为高浊和高硬度,在时间与空间上具有水量水质分配不协调的特点;基于此,重构了矿区矿井水水量平衡图,形成了矿井水井下-地面分级分质的综合利用技术,可将矿井水回用率提高到100%;同时,构建了兼具实时监测、无线传输与大数据储用的智能调配系统,为煤矿区矿井水的高效利用与多目标协同智能化控制提供了理论依据。

Due to the problems such as high reuse cost,uneven space-time distribution and low recycling utilization rate after mine water treatment,we explored the coupling change law of mine water quantity and quality in Dahaize Mining Area,through the analysis of mine water quantity balance and reuse water quality data.Big data computing and embedded system design are adopted to form the efficient underground-surface utilization approach and intelligent allocation technology of mine water in the mining area.The results show that the in-situ utilization rate of original mine water in Dahaize Mining Area is low,which is only 22.1%of the total mine drainage and the water is high turbidity and high hardness,which is characterized by uncoordinated distribution of water quantity and quality in time and space.Therefore,the balance map of mine water is reconstructed and the comprehensive utilization technology of mine water classification and quality classification are formed,which can increase the mine water reuse rate to 100%.At the same time,an intelligent allocation system with real-time monitoring,wireless transmission and big data storage is constructed,which provides a theoretical basis for efficient utilization and multi-objective collaborative intelligent control of mine water in coal mine area.
