Description

Technical Field

[0001] The invention relates to the technical field of water-retaining mining, and in particular to a tunneling water-retaining device based on mine mining and a control method thereof. Background Art

[0002] Due to the complex hydrogeological conditions in the mining area, there are abundant underground aquifers and fissure water bodies, and the water pressure is relatively high, which is easily released during the mining process. During the mining process, the rock strata may break, resulting in increased permeability of groundwater, and water enters the mine, causing water inrush accidents. When the mining work approaches or penetrates the underground gravel layer, quicksand layer and karst limestone layer containing water accumulation layers, it will cause water seepage accidents; once water seepage occurs, it will not only affect the normal production of the mine, but sometimes also cause casualties, flooding the mine and mining area, and the harm is very serious.

[0003] A drill is usually used to drill holes on the working surface, and then observe whether there is water seepage in the borehole to determine the water content inside the rock formation ahead. If the borehole penetrates into the water cavity in the rock formation, the water in the water cavity will flow out of the borehole. The detection results are not fed back in a timely manner, which is not conducive to timely blocking of the borehole and will increase the risk of water inrush. If the amount of water in the mine is too large, it will affect the production progress and personnel safety. In addition, the water in the aquifer inside the rock formation of the mine tunnel may penetrate into the mine tunnel through the gap, which may cause a water inrush accident in severe cases. The penetration of water may affect the structural stability of the rock formation around the mine tunnel, especially when the water continues to penetrate, the water may weaken the bearing capacity and structural integrity of the rock, and the water may cause the rock formation to swell, soften or dissolve, increasing the risk of rock collapse. Therefore, it is still necessary to monitor the inner wall of the mine tunnel. For this purpose, a tunneling water conservation device and a control method based on mine mining are proposed to solve the above problems. Summary of the invention
