Conveying versus trucking

Truck and shovel operation make up the majority of the surface operations worldwide, this is also the case here in Australia. However, considering high workforce cost and high focus on safety, one would expect the use of conveying systems to be a more popular option in Australia.

Importance of contracting standards

The mining industry sometimes responds so rapidly when commodity prices rise that contracting standards tend to drop in the mad rush to meet the next potential boom. One of our clients supplies dozers and earthmoving machinery to the Queensland coal mining industry. They have gone from having half of their fleet parked up, to having more work than equipment and then to considering buying new equipment over the course of a month.

Dump Scheduling and Haulage Simulation

One of the major financial impacts on any mine site is the number of trucks required to extract the coal/ore. By accurately evaluating the cycle times of individual haul routes from mining blocks to dump locations over the course of the mine life, the total amount of trucks at different years can be established. By evaluating alternate scenarios for dumping strategies sites can establish which option offers the lowest truck hours.

Coal Loss and Dilution – Drill and Blast

Drill and Blast is one of the leading causes of coal loss in an open cut coal mining operation. There are so many aspects that must be considered as part of the Drill and Blast Engineers design process and it is easy for an inexperienced or time constrained engineer to overlook critical areas. A poorly designed and managed blast can lead to millions of dollars of lost revenue.

Contracting and variations

Many years ago, when I was a young engineer working for a contract mining company at a large surface mine, a good friend (working for the client at the same operation) lamented the way contractors issue variations. From memory, I think he wanted to borrow a dozer for a few hours, and the contract didn’t provide for wet (operator included) hire.
