Water disaster prevention and treatment design method for mine taking coal bed as main aquifer

Abstract

The invention discloses a water disaster prevention and treatment design method for a mine taking a coal bed as a main aquifer, and the method is applied to coal mine down-hole use. By judging the water discharge amount of a working face water discharging system, whether working face partial syncline exists or not and whether a working face roof scouring zone and adjacent gobs exist or not, check computation and guarantee of the water discharge capacity of a working face and advancing gob ponding drainage are conducted. According to information collecting results of multiple objects and on the basis of corresponding judgment standards, specific water control measures are presented so that early warning of multiple water-inrush types can be provided, the loss caused by mine water disaster hazardous events can be reduced, and even personal casualties caused by the mine water disaster hazardous events can be reduced.

Description

technical field

[0001] The invention relates to a design method for preventing and controlling mine water disasters, in particular to a design method for preventing and controlling mine water disasters in coal seam-based aquifers used for waterproofing underground coal mines. Background technique

[0002] The problem of mine water inrush in my country has always been a major technical problem restricting mine safety production. In response to this problem, water inrush prevention and control methods have been formed at home and abroad, such as retaining waterproof coal pillars, dredging and reducing pressure, and rock formation grouting reconstruction. The hydrogeological characteristics of coal seam-based aquifers are discovered in coal mines for the first time, and there are no clear reports on this kind of mine water disaster prevention and control technology at home and abroad.
