Answering the question of whether winter pavements in high-cold-mine areas will become thinner, it would be better to observe from a full operating cycle rather than just static photographs. In the case of low-temperature, snow and frozen mines, for example, loading, moving, turning, stopping or lifting changes the stress, and material cryogenic performance and surface ice-freezing reliability often occur only in one action. To match the movement to the anomaly, we can find effective improvements.
The basic information required for this topic includes the replenishment cycle, the climate window, the length of the route, the most heavy vehicle, surface sensitivity and evacuation requirements. Upon completion of the measurements, the determination of temperature ranges from suppliers and the enhancement of smoothing, de-icing and damage screening could be used as an initial option to allow suppliers to explain why the pavement boards were applied, what tests the data were from and what was not covered by the assurance. Clear border conditions are more valuable to the project party than the single maximum carrying figure and facilitate future acceptance and accountability.

The product and field base should be used as a system for acceptance and acceptance when landing. The value of recyclable products is to reduce long-term surface disturbances and to support fast-tracking. Once the laying, support or lining is completed, full contact, flatness, edge transition, tight state and interference with tyres, feet, lifting bodies are checked; the pilot operation begins with low-risk work and is gradually restored to the planned capacity after the site manager has confirmed that there are no anomalies.
During the shift, changes in floods, freezing, sand, communications and alternative routes should be clearly reported, rather than just describing the current appearance. Connections, feed points or seams processed in the previous class are reviewed in the next class, and abnormally close rings are formed. During the clean-up process, it is prohibited to treat polymer surfaces with fire, violent banging or sharp shovels to avoid creating new vulnerabilities.
Receiving and inspection information shall keep the product batch, installation chart, site photographs, initial dimensions and trial running records. In the event of material cryogenic performance and surface ice impact reliability at a later stage, it may be determined whether the anomaly arises from initial installation, changes in condition or natural wear. For reusable pavements or leg pads, this set of records will also facilitate the rapid matching of suitable locations for the next transfer.
Prior to the issuance of the purchase order, the project manager should confirm the use of the same version of data by the technical, HSE, operational and logistics parties. The examples of specifications in this paper are not commitment values and the actual application is influenced by materials, temperature, foundation and installation. A complete submission would allow the vendor to make targeted recommendations on the size, quantity, packaging and spare parts of the pavement.

Applications, sizes, quantities, site photographs or drawings and delivery destinations are sent, on which we can identify more suitable products and processing programmes.
