A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, or rock dust.. Crushers may be used to reduce the size, or change the form, of waste materials so they can be more easily disposed of or recycled, or to reduce the size of a solid mix of raw materials (as in rock ore), so that pieces of different composition can be differentiated.
The production for a mine using sublevel stoping can range from 15 40 tons/employeeshift, while one stope can produce greater than 25000 tons per month. In general this method is fairly safe as the mining tends to retreat away from previously mined or unsupported areas.

Design of Surface Mine Haulage Roads – A Manual By Walter W. Kaufman and James C. Ault ABSTRACT This Bureau of Mines manual for design of surface mine haulage roads covers such aspects of haulage road design as road alignment (both vertical and horizontal), construction materials, cross slope, and drainage provisions.
Rock characteristics for both ore and waste are typical of those of granite or porphyritic material. Operating conditions, wage scales, and unit prices are typical for western mining operations. All costs listed are in 2012 US. The key design criteria, operating schedule, equipment, personnel, supply requirements and costs are listed below:

such as price, production and input costs. We expect revenues to continue to increase, on the back of higher prices and marginally higher production volumes, as demonstrated in Q1 2018. Despite the successes of costsaving initiatives to date, we expect operating costs to rise as a result of inflationary pressures on input costs.

Mining the Coal. Coal miners use giant machines to remove coal from the ground. They use two methods: surface or underground mining. Many coal beds are very near the ground''s surface, and about twothirds of coal production comes from surface mines. Modern mining methods allow us to easily reach most of our coal reserves.
