Design of Surface Mine Haulage Roads
During the past 30 years, surface mine haulage equipment has developed from trucks capable of moving 20 tons of material to vehicles that transport as much as 350 tons. Unfortunately, the design of roads this equipment must traverse has not advanced at the same rate. In many areas, road-building technology appropriate to vehicles of three
Mine Safety in Haulage and Transportation System
Apart from the falls of ground, haulage and transport operations have been responsible for a greater number of accidents involving deaths and injuries than any other single cause. The major proportion of haulage and transport accidents results from runaways. The various safety devices used on haulage roadways are as follows Stop blocks.

Integrated Optimization of Production Scheduling and Haulage …
In mining, deposits are divided into blocks, forming the basis for open-pit mine planning, covering production and haulage route planning. Current studies often stage optimization and lack the consideration of road capacity, leading to suboptimal solutions. A novel approach integrates production scheduling and haulage route planning through a bilevel optimization model.

Block Caving
Block caving is a gravity-based underground mining method that involves breaking up the rock mass located at depth into pieces. This method is particularly suitable for low-grade minerals or with disseminated mineralization. "Block" refers to the mining layout, which divides the ore bodies into blocks and large sections.
