Experimental Study of Non‐Darcian Flow Characteristics in Low‐Permeability Coal Pillar Dams

Groundwater
Abstract The safe operation of underground reservoirs and environmental protection heavily rely on the water flow through coal pillar dams in coal mines. Meanwhile, research on the flow characteristics in coal pillar dams has been limited due to their low hydraulic conductivity.
