Embodiment Construction
[0041] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.
[0042] Such as figure 1 Shown is a working flow diagram of a method for determining the water storage coefficient of a coal mine underground reservoir of the present invention, including:
[0043] Step S101 includes: establishing a three-dimensional similarity test model about the mine to be measured, and the three-dimensional similarity test model includes an overlying stratum, an aquifer, an aquifer, an underground reservoir stratum, and a floor stratum arranged sequentially from top to bottom.
[0044] Step S102 includes: performing coal seam excavation processing on the three-dimensional similarity test model.
[0045] Specifically, because the phreatic aquifer above the coal seam mainly has physical and chemical effects on the underlying rock formations (the confined aquifer also has hydraulic fracturing), so the similar simulat...
