Industry Standards for the Use of Coal Mine Anchor Rod Trays

The anchor rod tray exhibits excellent tensile strength, friction resistance, and radial friction resistance throughout its usage. Under these three standards, the anchor rod tray can perform exceptionally well in practical operations, with its effectiveness being fully realized only when applied within these parameters.
Many may be unfamiliar with the term "tensile strength," which primarily refers to the tensile and compressive strength of the anchor rod tray itself. This strength must exceed the tensile strength of the surrounding rock and soil to ensure effective operation. The principle of radial friction resistance operates similarly; normal functioning can only occur once radial friction resistance is generated between the anchor rod tray and the machine equipment.
A key principle in the application of the anchor rod tray is to enhance its bearing capacity by compensating for the reduced compressive strength and working capacity of soft rock masses.
