Prediction Of Water Inflow In A Mine In Ordos

The mine is located in the eastern part of Ordos City,Inner Mongolia Autonomous Region,the Wushenqi,the mine belongs to one of the world's eight coalfields Dongsheng-Shenfu coalfield.The coal mine in the coal field is famous for its large-scale mechanized mining with wide coal-bearing area,abundant coal resources,excellent coal quality and convenient mining conditions.The sandstone aquifer is the main water and aquifer in the mine.In this paper,the aquifer at the bottom of the straight coal group of 2-2 coal roof is forecasted.Based on the analysis of the study area and the hydrogeological conditions of the field,this paper understands the regional aquifer and the aquifers and their characteristics,the groundwater fill,the diameter,the row condition,the water source and the water intensity,and so on.By collecting the research area(GMS)software for three-dimensional hydrogeological modeling,and the groundwater numerical simulation is carried out.The groundwater simulation system is used to simulate the groundwater.Through the three-dimensional geological model in all directions of the division,detailed,specific,all-round show the details of the geological model,so that researchers and mine workers on the study area stratigraphy and aquifer have a whole understanding.Using the two methods of "big well method" and "numerical method",the method of forecasting the water content of the first mining face is forecasted.The groundwater numerical model of the mine is established by using the Modflow module in GMS software.After the stage of model identification and verification,the model is compared with the actual condition,and the water level is reduced to the height of the work surface,and the water level of the mine is calculated.Mine water inflow forecast results for the mine to provide the basis for safe production.
