Document Type and Number:
WIPO Patent Application WO/2018/192067
Kind Code:
A1
Abstract:
A water disaster prevention and treatment design method for a mine taking a coal bed as a main aquifer. By determining the water discharge amount of a working face water discharging system, whether working face partial syncline exists, and whether a working face roof scouring zone and adjacent gobs exist, check computation and guarantee of the water discharge capacity of the working face are conducted and gob hydrops are discharged in advance. The method is applicable to underground coal mines, and is able to propose a specific water prevention and treatment measure according to information acquisition results of multiple objects and on the basis of a corresponding determination standard, provide early warning for multiple water-inrush types, reduce the loss caused by mine water disaster hazardous events, and even reduce casualties caused by the mine water disaster hazardous events.
