Abstract

The invention discloses a measuring method for the water storage coefficient of an underground water reservoir of a coal mine and electronic equipment. The measuring method comprises the steps that the mining height, the advancing length, the thickness of each layer of a roof rock stratum, the caving angle of each layer of the roof rock stratum, the broken expand coefficient of each layer of the roof rock stratum, the original porosity and fissure degree of each layer of the roof rock stratum and the original volume of each layer of the roof rock stratum of the to-be-measured underground waterreservoir of the coal mine are obtained; the caving space volume of the roof rock stratum after coal seam excavation is determined according to the mining height, the advancing length, the thicknessof each layer of the roof rock stratum and the caving angle of each layer of the roof rock stratum; and the water storage coefficient of the to-be-measured underground water reservoir of the coal mineis determined according to the thickness of each layer of the roof rock stratum, the broken expand coefficient of each layer of the roof rock stratum, the original porosity and fissure degree of eachlayer of the roof rock stratum, the original volume of each layer of the roof rock stratum and the caving space volume of the roof rock stratum. According to the measuring method and the electronic equipment, the water storage coefficient of the underground water reservoir can be measured reasonably, and optimal design of reservoir capacity calculation of the underground water reservoirs, artificial dam body structures and the like can be achieved in a guided mode.

Description

technical field [0001] The invention relates to the related technical field of underground reservoirs in coal mines, in particular to a method for measuring the water storage coefficient of underground reservoirs in coal mines and electronic equipment. Background technique [0002] The water storage coefficient is defined by the water storage rate of the aquifer under the premise that the aquifer is elastic, that is, when the water head of the aquifer changes by one unit, the column whose bottom area is one unit and whose height is equal to the thickness of the aquifer The amount of water released (or stored) in the For an unconfined aquifer, the water released by its water storage coefficient is mainly composed of two parts: one is the elastic water volume in the lower part of the aquifer; the other is the water volume of the aquifer drained by one unit of water head change. [0003] Coal seam mining leads to deformation, damage, and collapse of the overlying strata. When ...
