Problems solved by technology

[0006] Due to the many uncertain factors in the coal mine underground reservoir, the emergency management system of the surface reservoir cannot be used effectively. Once an emergency occurs, such as the sudden collapse of the caving rock mass, causing a sudden increase in the water pressure in the reservoir, it is difficult to effectively guarantee Safe operation of underground reservoirs

Abstract

The invention discloses an underground reservoir with an emergency water draining device. The underground reservoir comprises a dam body and a working face gob area, wherein the working face gob area is formed in coal mining and is used for storing water; the dam body comprises a coal pillar dam body and an artificial dam body; the coal pillar dam body and the artificial dam body surround the working face gob area to form closed water storage space; the artificial dam body is provided with the emergency water draining device; and a filter screen is arranged on the back side of the artificial dam body. The invention also discloses a safe emergency treatment method for the underground reservoir. By the underground reservoir and the safety emergency treatment method for the underground reservoir, emergency water drainage is realized by the emergency water draining device, and the underground reservoir can run safely under emergency situations of mine earthquake, mining and sudden caving of caving zones.

Description

technical field [0001] The invention relates to the technical fields of coal mining and water conservancy engineering, in particular to an underground reservoir with an emergency drainage device and a safety emergency treatment method thereof. Background technique [0002] The western region is the main coal producing area in my country, with coal reserves and output accounting for about 2 / 3 of the country's total, but water resources are scarce, accounting for only 3.9% of the country's total water resources. The ecological environment is fragile, and water resources are scarce in this region. One of the bottlenecks of economic and social development. [0003] According to statistics, every ton of coal mined in the west discharges about 2 tons of mine water on average. According to the traditional treatment method, the mine water produced by coal mining is treated and then discharged to the surface. However, due to the large amount of evaporation in this area, the discharge ...
