Groundwater Occurrence Regularity Of The Huangling-Binchang Mining Areas

Huanglong-binchang mining area is an important coal industry base of Shaanxiprovince.With the excavation,water disaster is becoming more and more serious.Theproduction water and residents living water demand are also gradually increasing.Researchingthe low of groundwater has practical significance to people lives and mine production.Through analyzing geological exploration data，hydrological data and weather data ofHuangling-Binchang mining area,study Lower Cretaceous Series Luohe aquifer groundwateroccurrence basic characteristics,summary the mineralizing rules of groundwater,classify thehydrogenlogical units. It is mainly concluded that:(1)Luohe aquifer characteristics of roof andfloor structures control the vertical recharge and lateral runoff of groundwater character.Andits undulation state control the water-rich range in synclinal axis;(2)Thickness of Luoheformation determine aquifer water yield property.With the increasing of Luohe aquiferthickness,aquifer water yield property has a growing tendency;(3) Huangling-Binchangmining area is divided into two first-class hydrogenlogical units and four second-classhydrogenlogical units.Based on this,chose a range,which have classical hydrogeological condition and relativeindependentability hydrogeology unit,build hydrogeological conceptual model.Chosing VisualModflow software to simulate,using hydrological data distinguish and discern the model,andforecast the dynamic change of groundwater level from2009to2029.
