Information relating to the content of the manual was gathered through contacts with mining companies and equipment manufacturers across the country. Review of mining practices in some foreign countries also provided input. Literature sources relevant to good road design methods were reviewed and listed where appropriate in the text.

1.1.5 Ore extraction After a mining company has removed overburden, extraction of the mineral ore begins using specialized heavy equipment and machinery, such as loaders, haulers, and dump trucks, which transport the ore to processing facilities using haul roads. This activity creates a unique set of environmental impacts, such as emissions of

In mining operations, the layout of crushing plants and ancillary equipment and structures is a crucial factor in meeting production requirements while keeping capital and operational costs to a minimum. This paper addresses the critical design parameters as well as the consideration of ore

The electric power consumption by this process run on ore mining and processing enterprises is variously estimated as a value from 5 to 20% of overall world electric power.

Surface mining, wherever applicable, is more advantageous than underground mining in terms of ore recovery, operational flexibility, productivity, safety, and cost. Currently, almost all nonmetallic minerals (more than 95 percent), most metallic ores (more than 90 percent), and a large fraction of coal (more than 60 percent) are mined by ...

Most crushed and broken stone is mined from open quarries; however, in many areas, factors favoring large-scale production by underground mining are becoming more frequent and prominent. Surface Mining Surface mining equipment varies with the kind of stone mined, the production capacity
