The irregularity of the Mine Roof Support spacing setting is a common problem in the installation process, as shown by the fact that the Mine Roof Support installation spacing is too large and the spacing is uneven. For example, the following example of the problem.
Improper effects of Mine Roof Support spacing settings:
1) Mine Roof Support installation space is too large, the pipeline will be partially deformed and sunk, which will affect the safety of the pipeline.
2) Mine Roof Support has uneven installation pitch and poor installation.
Reasons why Mine Roof Support spacing is not standardized:
(1) The one-sided pursuit of labor saving and material saving, the spacing of Mine Roof Support is not set according to the pipe material, specification and size.
(2) The construction is arbitrary, and there is no overall consideration of the installation of the support (hanging).
Mine Roof Support spacing settings are not standardized:
Before the installation of the bracket, the slope and the starting point elevation should be calculated according to the pipeline design. The elevation of the intermediate points and the end point should be calculated, and the line should be well-grounded. According to the requirements of the standard spacing requirements and uniform arrangement, the mounting points and elevations of each bracket should be determined for installation.
