Prevention and Control Measures for Goaf Water in Coal Mines
In recent years,local governments have intensified efforts to integrate coal resources and shut down some small coal mines with low production capacity and poor safety in order to implement the national policy of"carbon peaking and carbon neutrality".These abandoned mines,accumulated over time,will produce a large amount of goaf water,which not only restricts the development of existing coal mines,but also lays hidden water hazards.To reduce the occurrence of water damage accidents in goaf,it is necessary to strictly implement the coal mine safety production system and take active and effective prevention and control measures.Through the understanding of goaf water and the discussion on the formation mechanism of goaf water,two accidents of goaf water inrush were listed,and the causes of the accidents were analyzed.A series of goaf water prevention and control technologies and measures were proposed,aiming to contribute to the safety production of mines.
