Method for distributed storage and use of underground water in mine

摘要

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.

1. A method for distributed storage and use of mine groundwater, characterized in that the method comprises the following steps:
A. prospecting an area to be mined, wherein the area to be mined comprises a strata, and acquiring basic geological data of the strata, wherein the basic geological data comprises bedrock geology; B. mining the area to be mined to form one or more goaf spaces; C. observing mine groundwater, and acquiring conditions of flow distribution, water quality data and water pressure data for the mine groundwater; D. designating the one or more goaf spaces having water retention ability as one or more designated water storage spaces of a distributed underground reservoir according to the bedrock geology acquired in step A and the conditions of flow distribution, water quality data and water pressure data for the mine groundwater acquired in step C; and E. mining a mining face adjacent to the one or more designated water storage spaces wherein mine groundwater generated during mining naturally seeps into the one or more designated water storage spaces as stored groundwater, wherein the mining face has a length, and wherein the one or more designated water storage spaces are increased by increasing the length of the mining face.
