Zusammenfassung: | The invention provides a cooperative disaster treatment hole structure and a cooperative disaster treatment method for a mine. A disaster layer of the mine comprises a bottom plate water layer, a coal mine gas layer and a mining subsidence layer which are sequentially distributed from bottom to top. The cooperative disaster treatment hole structure of the mine comprises a foundation hole and a treatment hole, the foundation hole penetrates through the mining subsidence layer, the coal mine gas layer and the bottom plate water layer; one end of the treatment hole is communicated with the foundation hole, and the other end of the treatment hole extends towards one or more of the bottom plate water layer, the coal mine gas layer and the mining subsidence layer. According to the method, one foundation hole is adopted, treatment holes of different well types are formed, various disasters are individually treated in a targeted mode, and three-dimensional cooperative treatment of various mine disasters such as water |
