Study On The Water Supply And Drainage System Of Jiangliyuan Iron, Jiangsu Province

Mine supply and drainage water is one of the basic security conditions for deposit mining engineering for safe and smooth production. For water supply and drainage systems in small and medium sized independent mining,pit flow is often an important source of production water.For drainage system in such a design, prediction mine water, has not only relationship between the production of safe deposit exploitation and mining water safety, but also relationship to the mining and water exchange between the surrounding environment.Take the Jiang Liyuan iron ore(Pei Country, Jiangsu Province)for example,based on mine water system to carry out mine drainage and mine with a view to making full use of the premise of water resources,technical basis is provided for the production of drainage water supply safety and reasonable size of the design.Jiang Liyuan iron ore is a complex hydrogeological conditions of small iron ore,Paleozoic Carbonate karst fissure water ,pore water overlying Mesozoic and Cenozoic loose,form a direct deposit filling water.Based on the current survey results and the combination of mine tunnel exploitation of design, hydrogeological conceptual model and the corresponding numerical simulation model of groundwater flow were established;using numerical simulation model,on the conditions of the mining mine water and the change process were predicted and evaluated;Mine water and the change process were combined with the rational development and utilization of mine water,and water supply and water distribution programs were determined to normal operating conditions,the scale of the drainage way. was determined to non-normal operation conditions.In view of mine water there is a big uncertainty in the analysis and determination.Based on analyzing and determining hydrogeological parameters and according to the related survey results,MC algorithm was used to calculate frequency distribution of parameters,combining with the numerical simulation model prediction, evaluating the risk of mine water,and the basis was provided for the design of the second water source.
