模糊数学法在深部矿坑水环境质量评价中的应用

Application of Fuzzy Mathematical Method on Deep Mine Water Environmental Quality Assessment

水资源危机越来越明显地影响矿山的可持续发展,有效利用资源成为矿山可持续发展的重要课题。对矿坑深层地下水进行水质评价并分类利用,是缓解矿山水资源危机的重要途径。云南会泽铅锌矿涌水量随着开采深度的加大而显著增大,应用模糊数学法和综合指数法对该矿区深坑水水质现状开展评价,结果表明,深部中段地下水水质较好,属Ⅰ-Ⅲ类水;其次,根据水量多年监测资料,得出可利用的稳定最低开采量为6500～11500m3/d,可以考虑用于矿山充填用水、采选厂用水、市政用水或生活用水。

Water crisis impacts sustainable development of mine more and more obviously.Effective use of resources becomes an important issue for sustainable development of mine.The quality assessment and classified use of deep mine water is an important way to relieve mine water crisis.With mining depth increasing in Huize lead-zinc mine,water inflow is significantly increasing.In this paper,deep mine water environmental quality was assessed by fuzzy mathematical method and comprehensive index method.The results showed that the groundwater quality of deep middle was good,which was Ⅰ-Ⅲ kind of water.In addition,according to monitoring data of water inflow in recent years,the available and stable minimum extraction volume of deep mine water was 6500-11500 m3/d,which was considered to be used as mine filling water,mining water,municipal water and domestic water.
