The Study Of The Controlling Mine Water Technology And Countermeasure In Fengfeng Mining Area

The hydrogeology conditions of Fengfeng mine area is complex. In history it had happened many times of water inrush. It’s a famous mining area of water hazard. With the mining depth increased, the mine threatened by the pressure of under floor is increasing. The situation of prevention water is grim. In the past three years, it has happened three times of Ordovician limestone water inrush in Fengfeng mine area and it has caused directly and indirectly huge economic losses. Therefore, it has important theoretical and practical significance for water controlling in Fengfeng mine area.The paper is base on the geological and hydro geological conditions of Fengfeng mine area, and analysis the water filling factors and subject to water damage of Fengfeng mine area. It summarizes the water inrush characteristics by statisticing some of mine water inrush in Fengfeng mine area. And it analysis the water inrush factors in fissure water inrush and fault water inrush and fall of the columnar water inrush. Proposed control measures for different water damage types. Finally it summaries the technology and countermeasures for Fengfeng mine area.
