In the event of an open-air mine at night and day, many teams will ask how thick the plates are needed; but the key to how the hot and cold linings of the mine truck are set aside is to confirm the defunct border. If a rigid locking results in a significant increase in the lifting of the arch, squeeze or hole torn after rainfall, full load or continuous operation, the state shall be used as a design condition and shall not be replaced by clear or airborne data.
The selection can be in three steps: the first step is to verify the hardness of the ore, the maximum size, the difference in the load, the temperature, the size of the car, the wear distribution and the life-target; the second step is to lock the dead in a rigid manner, leading to the conversion of the arch, squeeze or hole to the carrying, friction, shock or grinding needs; and the third step is to implement a stretch in the right direction by material data and installation programmes. The request for quotation documents should indicate the frequency, life expectancy and maintenance of the slabs. The increase in thickness usually also increases weight and handling difficulties and therefore cannot automatically be equated with “more suitable”.

If on-site space is restricted, progress cannot be moved by reducing the necessary coverage or moving points to the edge. Transport organization, equipment stationing or installation sequences should be re-checked to allow sufficient implementation space to set scalables in the right direction by material data and installation programme. The lining is both a waste material and part of the protection system of the car ' s structure. The first round of operations is reviewed immediately after completion, and early relaxation or relocation is usually easier to correct than long-term damage.
The site inspection should not simply be “normal”. The remaining thickness, hardware, edges, cracks and grass-roots corrosives shall be selected and the anomalies shall be classified into three levels: observation, restriction and decommissioning. In the event that repeated rigid locking in the same area results in arch-up, squeeze- or hole-to-pore tearing, a complete work order should be created. The removed plates or pads are cleaned, dry, flat and stored in salaried areas.
For temporary roads, the number of crashes, the length of blockages and surface repairs can be used as indicators; for leg support, the logs are evened and down; for carriage liners, the residue rate, lifting time and steel plate maintenance are tracked. Select two to four matches to this topic. As long as the caliber is fixed, a rigid lock can be objectively identified if it results in a change in the arch, squeeze or hole torn.
The conclusions can be summarized as identifying the boundary before choosing the slab, which will then be validated by checking data. Products shall not be used as substitutes for unsatisfactory foundations, damaged equipment or illegal operations. Where a person is involved in entering a dangerous area, a stop, quarantine and locking procedure shall be carried out; where a load and stability are involved, a review and written basis shall be carried out by a qualified person.
