The surface miner was developed in the mid-70s improving the design concept of the road milling machine, which were popularly used to cut the old road surface during road construction (Dey 1999).The surface miner essentially comprises a cutting unit, disposing unit (windrowing/conveyor loading) and propelling unit (Fig. 1a). The …
A study was conducted on rock samples collected from two limestone mines located in India where surface miner (SM), a popular drum type cutting machine, was used for excavation of rock.
This recent study reports an investigation on the effectiveness of the cutting performance models applied to the Surface Miner Wirtgen 2200-SM operation in a limestone quarry, Palimanan, Cirebon, Indonesia. The cutting models applied in this investigation are those proposed by [Gehring, K. H. 1989. Bestimmung von …
Cutting performance. The working performance by different types of surface miners in different rock formations is given in Table 5. Surface miner can cut oil-shale seams more exactly than rippers (2–7 cm) with deviations about 1 cm [10]. The production performance of a few surface miners used in Indian coal mines (Central …
The size of coal chips, produced during coal cutting operations, is of prime importance from the viewpoint of feed size desired by power plants. Proper chip size in cutting can eliminate primary crushing and in-turn save energy. Achieving a designated size of chip is intimately linked with the drum design inter alia the wrap angle, line …
2.1 Performance ranges of Surface Miners in crushable material The performance, tool wear and consequently the cost-efficient mode of operation of Surface Miners are decisively dependent on the mechanical prop-erties of the rock to be cut. In the following diagram, the performance ranges of the Surface Miners and cuttability of the vari-

Thus, perfor- User of the surface miners always finds difficulty in mance of a surface miner, generally, depends on cutting selecting suitable machines (for a mine) and also in in edges, curves, turning radius and length of working choosing their operating mode in short term (day to day area, truck changing time, which can be controlled by the ...
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.
