Surface miner, a continuous mining machine, is being manufactured in India and abroad owing to enhanced demand of production in various mining industries like coal, limestone, gypsum, bauxite etc. Different types of surface miners are manufactured today based on .
With its innovative, high-performance and cost-efficient products and technologies for cold milling, soil stabilization, hot and cold recycling, concrete paving and surface mining, WIRTGEN leads the world market in road construction and repair, as well as in mining natural rock and pay minerals.
Continuous miners. Though there are many variations in design, continuous miners mostly consist of five main elements: A central body to carry all other components mounted on some type of drive mechanism to provide mobility (most commonly tracks).
For mining medium-hard materials on the surface, "Continuous Surface Miners" have been employed for some years. The latest generation surface miner extends the performance of this type of machine to the point where the same cost efficiencies can now be achieved in medium-hard materials as has been achieved in softer materials by machines such as...
Mar 13, 2012· Application & Advantages of Surface Miner:Surface miner find their natural applications inprojects where drilling and blasting is prohibitedor where selective mining of mineral seams,partings and overburden is requiredIn India, since the coal has been formed with driftorigin and hence dirt bands in the coal seamsare mostly non-lenticular.It can ...
In room and pillar mining, rooms are cut into the coal bed leaving a series of pillars, or columns of coal, to help support the mine roof and control the flow of air. Continuous mining equipment is used to cut the coal from the mining face. Generally, openings are driven 20 feet wide and the pillars are generally rectangular in shape.
If so, maybe that's because you're a surface miner, will be a surface miner soon, or will soon work at a surface mine as a contractor. And if so, this is the article for you.

surface mining process – WIRTGEN developed a prototype based on road milling machines, the 3000 SM surface miner. Market entry was accomplished in 1983 when the fi rst machine, a 1900 SM surface miner, was sold. In keeping with market requirements, we then continued to develop ever larger machines for ever higher performance rates.
The continuous miner two-way radio remote is designed with the operator in mind, featuring large controls for common functions (easily differentiated by feel), common functions loaded to be close to the operators' natural hand positions, and uniquely shaped levers to differentiate functions.
