Abstract
The invention relates to a stepped established permanent underground water reservoir purification system, and belongs to the technical field of underground water reservoirs. The problem that in the prior art, water deeply going into a goaf cannot be treated or is not completely treated is solved. The purification system comprises a first region, a second region and a third region. A first separating wall is arranged between the first region and the second region, and a second separating wall is arranged between the second region and the third region. The first separating wall and the second separating wall are both vertically arranged. The first region, the second region and the third region are arranged in the seepage direction of underground water. The second region is provided with a primary water getting pipeline, and gotten water serves as industrial water. The third region is provided with a secondary water getting pipeline, and gotten water serves as domestic water. Water flowing into the goaf is purified stage by stage, and the purified water can meet the standard of the industrial water, and also can meet the standard of the domestic water.
Description
technical field [0001] The invention relates to the technical field of underground water reservoirs, in particular to a stepwise construction of a permanent underground water reservoir purification system. Background technique [0002] The strategic focus of my country's coal resources development has shifted to the central and western regions. In 2017, the raw coal output of 5 provinces including Inner Mongolia, Shanxi, Shaanxi, Xinjiang, and Ningxia accounted for 73.8% of my country's total coal output, and the ascertained coal resource reserves accounted for about the country's total reserves 80% of. This part of the area is in the arid-water-deficient zone and semi-arid-water-poor zone of our country, and the water resources are scarce, accounting for only 5.96% of our country. Water resources are the dominant factor affecting coal mining and ecological security in this region, and play a basic configuration role. Large-scale and high-intensity mining of coal mines will...
