Problems solved by technology

Although this patent has carried out relevant research on the retaining dam of the coal mine underground reservoir, the patent focuses on the stress on the main dam surface of the dam body, and does not consider the local weakness of the junction between the dam body and the roof and floor, let alone propose any means of treatment

Abstract

The present invention discloses an I-shaped water-retaining dam for an underground reservoir in a coal mine. The I-shaped water-retaining dam is located between coal pillar dams to isolate an underground reservoir from a corresponding coal roadway. The I-shaped water-retaining dam includes an upper flange plate, a web plate, and a lower flange plate from top to bottom, where a vertical face of a dam body is of an I shape; the upper flange plate extends into a roadway roof; two ends of the web plate are embedded into the coal pillar dams; and the lower flange plate extends into a floor. The I-shaped water-retaining dam is located in an underground coal roadway, and bears complex surrounding rock stress. The present invention effectively overcomes water seepage of a weak part at an upper part of a conventional I-shaped water-retaining dam.

Description

technical field [0001] The invention relates to the intersecting fields of mining engineering and water conservancy engineering, in particular to an I-shaped retaining dam of a coal mine underground reservoir. Background technique [0002] The construction of sluice gates and sluice walls is regulated in the "Coal Mine Safety Regulations" and "Coal Mine Water Prevention and Control Regulations", which are mainly based on the perspective of water prevention and control, without considering the long-term role of underground reservoir water storage; The construction of the dam body has been stipulated in more detail. Although there have been related studies on the construction of the retaining dam of the distributed underground reservoir in coal mines, the construction of the dam body of the surface reservoir and the construction of the retaining dam of the underground reservoir are obviously different. [0003] Comparing the dam body of the underground reservoir of the coal mi...
