Automatic Early Warning Method for Ground Collapse Risk in Coal Mine Goaf
Due to the special nature of underground mining environment in coal mines,accidents such as ground collapse,poisoning and suffocation are prone to occur in goaf areas.Especially,ground collapse accidents pose a huge threat to the safety of mining production and the living safety of nearby residents.Therefore,this paper proposes an automatic warning method for the risk of ground collapse in coal mine goaf areas.Obtain indicators such as geological factors,hydrological factors,environmental factors,and mining factors as the main factor indicators affecting the risk of ground collapse in coal mine goaf,and preprocess the missing values and normalization of the original influencing factor indicator data.Combining the analytic hierarchy process and information method,construct an early warning model.Input the influencing factor indicator data to obtain the predicted risk level of ground collapse in coal mine goaf,and issue warnings to high-risk areas.The case analysis results show that the ground collapse risk warning zoning map obtained by the design method is in good agreement with the actual on-site data,confirming the effectiveness and accuracy of the warning method.
