Swell & Void Percentage, Load Factors | |

When excavated, the material breaks up into different size particles that do not fit together, creating voids that reduce the weight per volume. For example, to hold the same weight of one cubic meter/yard of material, it takes 30 percent more volume (1.3 times) after excavation if the swell is 30 percent.

Why Measuring Loads Per Cycle is so Important in ...

 · A: Traditionally, systems give you a payload per cycle, or a load per cycle, but it''s measured during the cycle. So a truck that has a 45-tonne capacity might have 42 tonnes in its bed. Knowing that is great, but you can''t do anything about it. Because it''s measured halfway through the cycle, you can''t add material to the truck.

Underground Mining Methods and Equipment

Load-Haul-Dump units (LHDs), and rubber-tired shuttle cars and trucks, as well as transportation by conveyor, rail, and gravity flow. Ore is loaded into underground equipment and transferred to orepasses, wher e the ore is dumped. A drawpoint or chute is usually situated at the outlet of the pass on the lower level, where the ore is loaded and
