Maintenance planning and material management systems in productivity improvement in large mining operations

Abstract India is undergoing a massive electrification program using local coal to provide fuel for thermal generating plants. The Rajmahal mine in northern Bihar is scheduled to produce coal at the rate of 10 million tonnes per year by the end of a sixty-six month contract with MET-CHEM Canada Inc. for mine development. In order to control maintenance performance and warehouse inventory MET-CHEM is installing some proven computer-controlled programs and will provide extensive training to ensure that the systems are properly used. The programs are Maintenance Planning and Control System (MFCS) and Materials Management System (MMS), both of which were developed and used by Quebec Carder Mining Company at its iron ore mine in northern Quebec. In addition, a Predictive Maintenance Program (PMP) using vibration analysis will be introduced. This paper discusses the three systems.

Summary: Within six months from award of a project management contract, Les Mines Dumagami Limitee, Cadillac, Quebec, was operating its new hoisting facility. This was accomplished with less than a six-week shutdown of mine production while still maintaining shaft access for underground maintenance.
The work involved installing a refurbished 13.5 ft diameter double drum hoist, replacing a timber headframe with a new steel headframe, increasing the ore bin capacity from 500 tons to 1000 tons, construct...

Summary: A review of the major renovation of the fifty-year old C-l headframe facilities at NERCO's Con Mine, Yellowknife, N. W. T. is provided. The project was complete with only two 3-day shutdowns of the facility.
Work consisted of four major phases: structural reinforcement of the adjoining mill building prior to dismantling; relocation of virtually all mine and mill utilities which transited the headframe collar en route from the adjacent powerhouse; dismantling of the entire headframe facility...

Summary: Areas of bubble contact were delineated for cassiterite in the presence of chloride, fluoride, sulphate, phosphate, oxalate and citrate ions using dodecylamine hydrochloride collector. The limits ofpH, and the minimum collector concentration were established using the bubble pick-up technique.
Bubble contact did not occur below the p.z.c. (point of zero charge), estimated to be 4.7, in the presence of chloride ion, and fluoride ion showed only a weak response in the same pH range. These...

Summary: In 1988 a decision was taken to design and install a computerized mine monitoring and control system. This system had to monitor and control all pumping and ventilation underground. The operation of the mine air heating, using waste heat from the mine water and compressors, was to be part of the system. It ultimately also had to interface with the four existing Canadian General Electric Series 3 PLC's which controlled the No. 3 shaft loading pockets. Beside operational control and trouble...
