Methods, devices, and storage medium for synchronous treatment of water hazard and subsidence

A device for synchronous treatment of water hazard and subsidence, comprising:

• a first module, configured to explore rock strata between a coal seam and a ground surface to determine basic data of the rock strata, wherein the rock strata include a key stratum;
• a second module, configured to, in response to determining that the basic data meets a preset condition, set a plurality of monitoring holes on the ground surface based on a drilling position, wherein bottoms of the plurality of monitoring holes are located on a side of the key stratum in the rock strata away from the ground surface;
• a third module, configured to, in response to determining that the coal seam is mined, perform water injection pressure monitoring on at least one monitoring hole of the plurality of monitoring holes within a preset range at intervals of a preset time, wherein the preset range is determined according to a mining position of the coal seam;
• and
• a fourth module, configured to, in response to determining that a pressure change of the water injection pressure monitoring performed on any monitoring hole of the plurality of monitoring holes meets a first requirement, perform grouting on the any monitoring hole until a grouting pressure of the any monitoring hole reaches a second requirement.
