Support Function
Used with Rock Bolts: Mining trays are usually used together with rock bolts. In the surrounding rock support of mining operation spaces such as roadways, the rock bolts go deep into the rock mass. The trays are installed at the exposed ends of the rock bolts. By tightening the nuts, the trays transfer the anchoring force of the rock bolts to the surface of the surrounding rock, exerting a squeezing and reinforcing effect on the surrounding rock, preventing the surrounding rock from deforming and loosening, maintaining the stability of the roadway, and ensuring the safety of personnel and equipment during underground operations.
Fixing Anchor Cables: In some scenarios that require stronger support force, anchor cable support will be used. Mining trays can also be used to fix anchor cables, so that the tensile force exerted by the anchor cables acts evenly on the surface of the rock mass, enhancing the anchoring effect on the deep rock mass and controlling the large deformation and damage of the rock mass.Stress Distribution
Uniform Load Transfer: During the mining process, the surrounding rock is subjected to various stresses. Mining trays can disperse the concentrated load exerted by rock bolts or anchor cables to a larger area of the rock mass, avoiding rock mass damage caused by local stress concentration, and improving the reliability and stability of the support structure.
Buffering External Impact: When dynamic disasters such as roof collapse and rock burst occur in the mine, the tray can play a certain buffering role, reducing the damage to rock bolts and anchor cables caused by instantaneous impact force, enabling the support system to continue to function, and protecting the underground operation space and the safety of personnel.Assisting Installation and Maintenance
Facilitating Installation and Positioning: When installing rock bolts or anchor cables, mining trays can be used as a reference surface, facilitating construction personnel to accurately position and install the rock bolts and anchor cables, and ensuring the installation quality of the support system.
Facilitating Inspection and Maintenance: In the daily safety inspection and maintenance of the mine, the state of the mining tray can intuitively reflect the working condition of the support system. If the tray is deformed, loosened, etc., problems existing in the rock bolt and anchor cable support system can be discovered in a timely manner, so that corresponding maintenance measures can be taken to ensure that the support system is always in a good working state.
