The invention relates to the technical field of mineral resource mining, in particular to a water inrush prevention method and device for ground pumping and draining overlying strata separation layer water, a terminal and a storage medium. According to the implementation mode, the position of a main separation layer is obtained firstly, the position of the main separation layer is used for representing the direction of the main separation layer, then the position of a drilling hole is determined according to geological conditions and the position of an open-off cut, and then the position of the drilling hole is determined; and when the advancing position of the working face meets the preset condition, a drainage hole is drilled in the drilling position according to the main separation layer position, and finally water of the overlying strata separation layer is drained through the drainage hole. Through the step of determining the main separation layer position, the depth of the separation layer space water level causing water inrush of the target working area can be determined, then the drilling position is determined according to the geological condition, and it is guaranteed that separation layer water can be pumped and discharged as much as possible. The drilling is performed when the working face is advanced to meet the preset condition, so that the severe active period of overlying strata can be avoided.
Description
technical field [0001] The invention relates to the technical field of mineral exploration, in particular to a method, a device, a terminal and a storage medium for the ground pumping and draining of overlying rock abscission water for preventing water inrush. Background technique [0002] After the coal seam is mined in the mine, the overlying stratum is unevenly damaged and deformed due to the difference in thickness, lithology and strength, and transverse cracks will appear between the upper and lower strata of different hardness, which is the so-called separation layer. [0003] When the overlying rock layer is a water-rich rock layer and the underlying rock layer is a soft rock layer, it will accumulate into a layer water body within a certain period of time. With the continuous advancement of the working face and the accumulation of time, the water volume and water pressure in the closed abscission space continue to accumulate. When the working face advances a certain ...
