Subject : Groundwater Occurrence Regularity of the Huangling-Binchang Mining Areas Specialty : Mineral Resource Prospecting and Exploration Name : Mu Pengfei (Signature) Instructor : Wang Ying (Signature) Wang Xin (Signature) ABSTRACT Huanglong-binchang mining area is an important coal industry base of Shaanxi province.With the excavation,water disaster is becoming more and more serious.The production water and residents living water demand are also gradually increasing.Researching the low of groundwater has practical significance to people lives and mine production. Through analyzing geological exploration data，hydrological data and weather data of Huangling-Binchang mining area,study Lower Cretaceous Series Luohe aquifer groundwater occurrence basic characteristics,summary the mineralizing rules of groundwater,classify the hydrogenlogical units. It is mainly concluded that:(1)Luohe aquifer characteristics of roof and floor structures control the vertical recharge and lateral runoff of groundwater character.And its undulation state control the water-rich range in synclinal axis;(2)Thickness of Luohe formation determine aquifer water yield property.With the increasing of Luohe aquifer thickness,aquifer water yield property has a growing tendency;(3) Huangling-Binchang mining area is divided into two first-class hydrogenlogical units and four second-class hydrogenlogical units. Based on this,chose a range,which have classical hydrogeological condition and relative independentability hydrogeology unit,build hydrogeological conceptual model.Chosing Visual Modflow software to simulate,using hydrological data distinguish and discern the model,and forecast the dynamic change of groundwater level from 2009 to 2029.
