Determine the location of the roadway according to the minimum transportation work

When determining the location of the main development roadway, the ore transportation cost during the mining process should be minimized. The cost of underground and surface transportation of ore is proportional to the product of transportation volume and transportation distance. We refer to the product of transport volume and transport distance as transport work. The billing basis for transportation costs is related to the transportation distance and also to the wellbore position. A reasonable wellbore position should be minimized in the underground surface transport of the ore.

In order to reduce the transport work, there should be no reverse transport between the underground and the surface. In addition, under the conditions of transport equipment and similar transportation distance, surface transportation costs are often lower than underground transportation costs. The minimum transportation work is determined to mainly develop the position of the roadway. Generally, no quantitative calculation is performed, and only a qualitative analysis can be performed.
