A mine drainage structure

Abstract

The invention discloses a mine drainage wind-shielding structure, which relates to the technical field of underground mining, and comprises a drainage well and a drainage roadway, the drainage roadway connects the bottom of the drainage well and a sedimentation tank, and a front half wall and a rear wall are arranged in the drainage roadway. The half wall is stacked, the front half wall is located at the upper part of the drainage roadway, the rear half wall is located at the lower part of the drainage roadway, the top of the rear half wall is higher than the bottom of the front half wall, and the rear half wall is provided with a gate. It can not only seal the wind flow, but also discharge water, and can also play the role of a sedimentation tank. When the gate of the rear half wall is closed and the water is stored at the position of the front half wall, regardless of the amount of water inflow in the mine, the front half wall is always submerged in the water to separate the drainage well from the sedimentation tank, which is beneficial to eliminate or reduce the water flow to the mine ventilation It is beneficial to reduce the number of ventilation structures, improve the effect of mine ventilation, and also help to improve the effect of mine sedimentation.

Description

technical field [0001] The invention relates to the technical field of underground mining, in particular to a mine drainage and wind-shielding structure. Background technique [0002] For mines that adopt underground mining methods, in order to ensure the continuous safe production of mines, a series of tunnels need to be excavated from the surface to the underground to form a system of lifting, transportation, ventilation, power supply, air supply, water supply, drainage, communication, etc., in a timely manner. Excluding mine water gushing is an important part of mine flood control and flood fighting, especially for mines with large water gushing. [0003] According to the topographic and geological conditions of the mine and the overall planning and layout of the development project, in addition to artesian drainage, the drainage system construction plan can be divided into one-stage drainage, segmental drainage, centralized drainage and partitioned drainage. Among them,...

Problems solved by technology

The current practice is to set up ventilation structures in the contact roadway outside the sedimentation tank to isolate the drainage roadway from the transportation roadway, so as to prevent the influence of water flow on the ventilation of the mine. When the sedimentation tank needs to be cleaned, these ventilation structures will change. The balance state of the original system affects the mine ventilation effect
