In order to answer the question as to how many of the mine shifts cross the temporary road risk, it would be preferable to observe from a full operating cycle rather than looking only at static photographs. In the case of night work and the rapid change in day-to-day road conditions, for example, loading, driving, turning, stopping or lifting would change the stress, and failure to turn to the soft spots and speed limits would lead to repeat events often occurring only in a given operation. To match the movement to the anomaly, we can find effective improvements.
In establishing the input list, the vehicle number, shift, route, event, maintenance hours, material consumption and operating records should be placed in the same table, with an indication of the data source and date. In the case of non-transaction soft points and speed limits, which would lead to repeat events, the recommended direction is to communicate the unclosed risk with map positioning, site marking and electronic worksheets. The three types of product are then compared with specifications, size differences, temperature ranges, connections and test conditions; if the two suppliers have different support bases or test methods, the nominal data cannot be arranged in a simple horizontal manner.

The quality of the installation should be reviewed through photographs and measurements, not just oral confirmation. First, they deal with drainage, tatters or deforming steel plates, and then place three types of products in accordance with approved drawings; they include the same set of asset management for roads, support and carriage liners. Any need for temporary blocks of wood, random cutting of angles, forced porosity or stacking should be returned to the technicians for re-evaluation.
For high-utilization mines, changes in trends, repeat failures, unclosed worksheets and training deviations could be incorporated into mobile end-line sheets and location photographs required. The system should automatically raise the level of inspection if it continues to capture unconnected soft points and speed limits that would lead to repeat events. Replacements in the inventory are also periodically counted in size and state to avoid any lack of matching, shortage of connectors or storage of deformations during emergency maintenance.
Cost models should cover procurement, transportation, installation, maintenance, cleaning, warehousing and evacuation sites, taking into account non-delivery of soft points and speed limits that would lead to a repeat incident-induced shutdown and re-entry. A baseline of one month or a full rainy season could be used to evaluate the improvement programme. In the absence of a sufficient sample, uncertainty should be clearly marked and the full year ' s benefits should not be inferred from a successful case.
The safety floor does not change due to the tight working schedule. In the event of an unknown foundation, posturing of equipment in excess of the Manual, damage to components or failure to isolate persons, operations should be suspended and approvals upgraded. Any improvement in the failure to transfer a soft spot or speed limit that would lead to a repeat event must be confirmed without the introduction of a new slide, overload, trip or maintenance risk.

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