Research on Safety Early Warning System Based on Dynamic and Static Indicators in Coal Mining Faces
A comprehensive analysis was conducted on the frequent occurrence of accidents in coal mining faces,and a safety warning framework for working faces was designed.Combining the principle of single indicator warning and the characteristics of geological safety,equipment safety,personnel safety,etc.,a dynamic and static indicator fusion safety warning model was proposed.Through practical verification,the comprehensive warning index of geological safety indicator warning U5i obtained by incorporating dynamic weight function is shown as 0.799 8.When the index is exceeded,the system will issue a safety alarm,effectively avoiding the occurrence of coal mine accidents.
