Abstract
Disclosed is a method for distributed storage and use of mine groundwater. The method comprises the following steps: A. prospecting an area of an underground space to be mined, and acquiring data on the bedrock geology of the strata; B. observing the mine groundwater, and acquiring the conditions of the flow distribution, water quality data and water pressure data for the mine groundwater; C. designating one or more goaf spaces through which mine groundwater cannot permeate as a water storage space of a distributed underground reservoir according to the data on the bedrock geology of the strata acquired in step A and the conditions of the flow distribution, water quality data and water pressure data for the mine groundwater acquired in step B; and D. after the designated water storage space is formed, mine groundwater generated when mining a mining face adjacent thereto naturally seeps into the water storage space. The method can reduce mine groundwater run-off and the effect on the growth and recovery of the ecological environment.
