The Total Mining System (TMS): The basis for open pit automation

Abstract
With the implementation of more advanced monitoring, control and locating systems in surface mines, there is an ever increasing need for their mine-wide integration toward achieving over-all optimization. AQUILA Mining Systems Ltd. is developing the basis for a comprehensive real-time monitoring, control and information system called the Total Mining System or TMS. This system is being designed to address both current and future needs of open pit mines toward improving productivity and minimizing costs, through better two-way information flow between each component in the operation. At a basic level, feedback from equipment and process monitoring will enable decision making to be based on quantitative, on-demand information, thus permitting proactive rather than reactive planning. Dynamic planning would be a valuable tool as market conditions fluctuate, equipment fleets age and variations in the grade, quality, geometry and hardness of the mined material all contribute to either changing production targets or levels of achievable performance. Such a capability could be implemented within the next two years.
At a higher level, and within five years, autonomous operation and/or real-time supervisory control of mobile and stationary equipment in open pit mines will be achieved. A discussion is provided in regard to the development and implementation of an autonomous haultruck and blasthole drill, to demonstrate the need for such a system.
This paper outlines a preliminary program for the design, development and implementation of this system, primarily in relation to high-level communications and its role in the future automation of open pit mobile equipment.

Summary: The in pit dam construction and utilities relocation, known as the East Mine Corridor Relocation (EMCR) project, was developed to extend the life of the east side of the Base Mine pit by two years. This will result in the recovery of an additional 80 million barrels of oil and delay expenditures associated with the opening of the North Mine by two years. To accomplish this, a large in pit earth structure was required to provide a new embankment foundation for relocating a public highway, four...

Summary: This paper reviews an analytical model that defines the relationship of weight-weighted or volume-weighted average haulage distance with bench height and other related parameters, presents the optimum bench heights under various conditions in terms of minimizing the weighted average haulage distance of ore/waste during the full lifetime of an open pit mine, and discusses the truck-haulage economics of mining open pits by high bench, specifically by 15 m, 18 m and 20 m benches through marginal...

Summary: Miller chlorides, which are a mixture of silver and copper chlorides, are produced when impure molten gold is refined with chlorine. Usually the copper and silver are recovered from the chlorides by a hydrometallurgical cementation process. However, this process is slow, requires considerable floor space, and generates waste water solutions which are not environmentally acceptable. In the present work, the pyrometallurgical reduction of the Miller chlorides was investigated according to the...

Summary: Geostatistics has been widely accepted as a standard tool for reserve estimation and mine planning. Kriging has been adopted as the best estimator of grade. Although many discussions have been conducted in the use ofkriging in the mining industry, insufficient attention has been given to solutions for over-smoothing. This effect has been frequently encountered in many mines. The so-called over-smearing refers to two facts: (1) over-reduction of grade variabilities and (2) over-estimation of...

Summary: Omai Gold Mines Ltd. is the operator of a large-scale open pit gold mining operation located in Guyana, South America. Construction at the mine began in September 1991 and the process plant of a capacity of 12 000 tonnes per day reached commercial production in January 1993.
The remote location of the mine requires an extensive logistics support to ensure adequate material supplies. Over 60% of the consumables valued at US$35.0 million per year are supplied from North America.
One particular...
