Application of Analogy Method in Mine Water Inflow Prediction:Taking Yushen Phase Ⅲ Mining Area as an Example
Yushen phase Ⅲ mining area is located in an important ecological function area for wind prevention,sand fixation and water conservation.Groundwater is important to maintain the regional ecosystem.Accurate estimation of mine water inflow is of great significance for regional groundwater protection.The existing methods for predicting mine water inflow in China are mainly divided into two categories:deterministic methods(including numerical simulation method,analytical method,etc.)and non-deterministic methods(including analogy method,fuzzy mathematical model,time series analysis,etc.).This study uses the analogy method to analyze the hydrogeological conditions,geological structure zoning,coal seam burial depth,influence of water conducting cracks,and retaining thickness of aquifers of each proposed analog mine.The mine to be analogized is determined within the mining area or adjacent areas,and conditions such as mining scale,mining method,and mining face at each stage of the mine are further analyzed.The prediction results of mine water inflow are obtained,and the prediction results of mine water inflow using different methods are compared.Reasonable use of analogy methods to predict mine water inflow can provide more accurate data support for formulating scientific countermeasures for mining areas with sensitive water environment protection targets in the surrounding area,as well as mining areas where the stability of the ecosystem is significantly affected by groundwater resources.
