Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of coal mining, and in particular relates to a coal seam roof waterproof supporting device. Background Art
[0002] The coal mine roof refers to the rock layer above the coal seam in the coal mine, also known as the coal seam roof. The coal seam roof is divided into pseudo roof, direct roof and old roof. In coal mining engineering, the roof refers to the rock layer located a certain distance above the coal seam. The underground rock layer or coal seam is solid. The weight of the upper rock layer presses on the lower rock layer, which is in a state of equilibrium. At this time, the rock mass does not deform or move. After we dig a tunnel in the coal seam or rock layer, the rock layer at the top of the tunnel will fall down. The weight of this top rock layer presses on both sides of the tunnel. This top rock layer is the roof.
[0003] Coal roof watering is one of the main factors affecting and restricting the coal mine operating environment. Generally, due to the weak water-rich nature of the roof aquifer and the large mining area, the amount of water provided is limited and does not pose a major threat to mine safety. However, the dispersed nature of this water can significantly impact the working environment, hinder mining operations, and restrict production.
[0004] Therefore, it is necessary to propose a coal seam roof waterproof support structure to solve the above problems. Utility Model Content
