| titleOfInvention | Floor Water Inrush Early Warning Method |
| abstract | The invention relates to the technical field of coal seam floor water inrush prediction, and provides a floor water inrush early warning method. The method includes: collecting monitoring area data, obtaining relevant numerical information; arranging optical fibers, and making the optical fiber horizontal section of the optical fiber guide upward along the Austrian ash water The top surface of the belt is laid out; the initial thickness of the aquifer and the initial value of the water pressure at any point in the horizontal section of the optical fiber are determined; the variable data of the water pressure at any point in the horizontal section of the optical fiber and the real-time height of the Austrian ash water mining guide are obtained in real time through the optical fiber. The real-time water pressure value is obtained through the water pressure variable data and the initial value of the water pressure; the actual thickness of the aquifer is obtained through the initial thickness of the water-resisting layer and the real-time height of the Austrian ash water mining guide, and the real-time water pressure value and the Austrian ash water mining The real-time value of the water pressure is obtained by the real-time height of the guide; the actual thickness of the aquifer and the real-time value of the water pressure are monitored in real time for early warning. This method can locate the water inrush points within the monitoring range, issue early warnings, and provide data support for coal mine safety production. |
