Premron's Continuous Haulage System (CHS) project, meanwhile, will revolutionise coal mining in underground mines, according to METS Ignited. It eliminates the use of shuttle cars, used to take the coal cut from the wall of the mine to a transfer point further away in the mine (dead time).
Continuous Haulage Systems can be tailored for your specific projection, and can be easily installed in new or existing operations. They are as reliable and trouble-free as any piece of face equipment available today. Up to 34.5-tonne-per minute / 38-ton-per-minute capacity; Attached or …
The continuous haulage system serves the requirement to mine underground mineral deposits in a way that increases the efficiency of a continuous mining machine by maximizing the machine utilization, which means eliminating the waiting for an intermittent material clearing system in the likes of a shuttle car. The continuous haulage system will ...
Detailed observations were made for two existing continuous miner and shuttlecar systems. A simple model for the shift average cycle consisted of three time components – delays, mining and transport. Cycle improvement and productivity improvement factors are derived and used to predict the theoretical improvement which the observed cycles could achieve.

mining is the most common, representing more than half of all underground production. In this method, a continuous mining machine excavates the coal and loads it onto a conveyor or shuttle car in a single step. Despite the term "continuous," the machine operates only part of the working time, because after mining advances

The term "continuous" as applied to development machines has been one of the biggest misnomers used for mining equipment because, on development, they are usually anything but continuously cutting. The main delays mostly occur while roof support is installed and often waiting for shuttle cars to return from their discharge point for reloading.
