Due to the collapse of coal mines, iron ore, etc., or collapse, etc., and various external factors cause deformation of some parts of the roadway, which seriously affects the safe use of mine roadways. The Underground Roof Support is a kind of mine support. It has high tensile strength, high compressive strength, good toughness, high support strength and can be reused many times. It is widely used in mine roadways, especially in Deep complex roadway and soft coal seam roadway.
In order to prevent the roadway from continuing to deform, causing roadway damage or landslide accidents, paving the way for the re-activation of the mine, the Underground Roof Support is generally selected. The Underground Roof Support is mainly used for the secondary support of the mine roadway and the mine roadway of the mountain tunnel. To increase the pressure resistance of the roadway section. In order to ensure safe construction, the following safety technical measures are formulated.
When replacing the used shed, you can flexibly choose the type, structure and shed distance of the Underground Roof Support, and carry out the construction and installation in strict accordance with the relevant parameters to ensure that it works effectively, safely and reliably. Only the correct installation and use of the Underground Roof Support can speed up Roadway excavation speed, reduce the amount of backtracking in the roadway, ensure safe production, extend service life, and obtain better technical and economic benefits, so as to play the performance of the Underground Roof Support .
