(PDF) NEW METHODOLOGY TO IMPROVE PRODUCTIVITY OF MINING

Process improvements can be higher mining productivity, higher mill throughput, decreased overall operating costs and higher flotation or leach recovery. This paper

Productivity in the Mining Industry: Measurement and

Yet output growth in mining in recent years has been weak at best, and multifactor productivity (MFP) has declined by 24 per cent between 2000-01 and 2006-07. Long lead times between investment in new capacity in mining and the associated output response can lead to short term movements in mining MFP unrelated to underlying efficiency.

In order to achieve this productivity, two teams of 2 workers per stope and a nipper are working on rotating 10-hour shift. The teams assigned to a stope are responsible for the breakage, haulage to the orepass, remuck and stope preparation for the backfill. Homestake Mining Co Homestake Mine (U.S.A)

Therefore, the production of equipments used in each step depends on the production of previous equipment. That means utilization of each equipment affects the others. • The capacity of mining equipment is huge.

Primary Mining Method Modified Avoca. Information. The following parameters were used in the productivity planning: Two-boom Jumbo: 240 m/month (787 ft/month) for one single heading available and 260 m/month (853 ft/month) for multiple headings available.

Mining productivity and efficiency improvement or

Productivity is about production levels over a defined period of time (eg tonnes of coal per annum) and may consider factors such as the quality of material produced. A plan to improve productivity might look at a pit’s design or a mining method.

Dawson looks at terrace mining to improve productivity

2012-6-14  “Moving to the terrace method means the mining equipment is not limited to a dragline strip width, allowing for wider dig faces to maximise the productivity of the truck and shovel equipment compared to the existing operation,” Perkins said.

2018-3-11  Some variations of the room-and-pillar mining method include post room-and-pillar mining and step room-and-pillar mining. Post room-and-pillar mining is a combination of room-and-pillar mining and cut-and-fill stoping mining, whereas step room-and-pillar mining is a variation of room-and-pillar mining in which the footwall of an inclined ore body is adapted for use of trackless equipment.

Primary Mining Method Sequential grid down dip. Information. To deal with ground pressures, a V-shaped mining sequence is utilized. The main advantages of the sequential down dip method are the very low energy release rates, which make backfilling unnecessary, and the allowance for the physical separation of rock transport from men and materials.
