Analysis of Mine Water Filling Factors and Prediction of Mine Water Inflow in SS Well Field,Fengcheng City
The purpose of this paper is to analyze the water filling factors of the Shishang well in Fengcheng City,Jiangxi Province,and scientifically and reasonably predict the water inflow of the mine to ensure the safety pro-duction of the mine and the data support of relevant departments in coal resource mining decisions.Selecting the Shishang well field as the research object,a detailed analysis of hydrogeological conditions was conducted,and two methods,"groundwater dynamics method"and"hydrogeological comparison method",were used simultane-ously to predict the inflow.The main water filling factors in the mining area include atmospheric precipitation,karst fissure water,and fault water.The main aquifers are the Quaternary pore aquifer,the Neogene red layer con-glomerate fissure karst aquifer,and the Triassic Lower Daye Formation limestone karst aquifer.Using groundwater dynamics method to predict,the water inflow of B4 coal seam is 2095.2 m3/d;Using hydrogeological comparison method,the water inflow of B4 coal seam is predicted to be 2006.64 m3/d.The predicted results of both methods are higher than the actual average water inflow,but lower than the maximum water inflow,indicating the reliabili-ty of the predicted results.Based on the predicted results and coal mining requirements,it is recommended to de-sign the mining according to the maximum water inflow value to improve mining safety.
