Our Bronze, Silver, and Gold series tools are the good, better, and best levels of tools to meet condition, machine, and budget demands. Gold Series
In 1938, the company shipped its very first shuttle car – the Model 2ET-1D – cementing its position as a leader in underground mining equipment. In 1948, the company produced its first continuous miner – Model 3JCM – the beginning of the now extensive product line of continuous miners and entry drivers.
Surface mining, including strip mining, open-pit mining and mountaintop removal mining, is a broad category of mining in which soil and rock overlying the mineral deposit (the overburden) are removed, in contrast to underground mining, in which the overlying rock is left in place, and the mineral is removed through shafts or tunnels.
The comprehensive range of mechanical cutting equipment offers effective solutions for a wide range of underground mining and construction applications such as rapid-entry roadway development, demanding production settings without drilling and blasting, as well as boring of ore passes and ventilation shafts.

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. We develop both the machines and the technologies.
Applicability of a surface miner (SM) must be based on a careful assessment of intact rock and rock mass properties. A detailed literature review was made to identify different parameters influencing the performance of various types of cutting machines deployed in different parts of the world. The critical parameters influencing the production, diesel consumption and pick consumption of SM in ...
The new Surface Miner 2200 SM 3.8 A continuous process of improve-ment for our customers' beneﬁ t is one of the fundamental com-pany philosophies cultivated by Wirtgen – the market leader in surface mining. Increasing both the cutting perfor-mance and effective uptime is one of our main priorities in surface mining. Continuous process
SURFACE MINE BLASTING Proceedings: Bureau of Mines Technology Transfer Seminar, Chicago, IL, April 15, 1987 Compiled by Staff, Bureau of Mines ABSTRACT The Bureau of Mines has sponsored a comprehensive research program to enhance the safe, effective, and efficient use of blasting technology by the mining industry.
Cutting tools for continuous miners. offers a wide range of extremely productive and reliable continuous miner cutting tools for bord and pillar mining. Cutting tools for roadheaders and miners. has a wide selection of highly productive conical mining tools for roadway development with the toughtest carbide grades in the industry.
Powerful Cutting Drum Unit. The cutting drum is designed specifically for demanding windrow applications in soft rock, such as coal or salt. Maximum cutting performance combined with the ideal use of engine power and low specific fuel consumption allows raw materials to be mined in an extremely cost-effective process.
What is a Terrain Leveler® surface excavation machine (SEM) used for? Put this machine to work in your surface mine, quarry or civil construction application. Whether you're prepping a site for civil construction, surface mining or extracting aggregates from a quarry, the Terrain Leveler SEM can help you be more productive.
Wirtgen surface mining technologies. In 1980, Wirtgen built the first surface miner for the mining of minerals in opencast deposits. Today, Wirtgen is the market leader in this segment, offering a technically mature product portfolio for opencast mining which has been tried and tested in operations around the globe.
Global is the largest surface miner contractor in the world and has been at the forefront of the development of surface mining; helping to deliver lower mining costs, and providing major safety and environmental benefits for mining operations.
WIRTGEN surface miners cut primary resources such as coal, gypsum, iron ore, salt, phosphate, bauxite, limestone or granite, achieving high degrees of purity in the process. They are increasingly used as primary extraction equipment also in newly opened-up opencast mines or extensions of existing opencast mine operations.
New Wirtgen 220 SM 3.8/220 SMi 3.8 Surface Miner: Maximum Performance in Soft Rock. Wirtgen's 220 SM 3.8/220 SMi 3.8 surface miner selectively mines raw materials up to a cutting depth of 350 mm and a uniaxial compressive strength of 35 MPa.
Surface mining is defined as the extraction of ore from an open pit or burrow. Surface mining is sometimes known as open-pit, open-cut or open-cast mining and is only commercially viable if the deposit is located relative close to the surface. Less than 20% of Alberta's bitumen reserves are close enough to the surface to be mined.
When it comes to surface mining equipment, no one has more experience helping miners match the right product to a specific need than . Ranging from dozers, drills and draglines to trucks, shovels, loaders and a host of support equipment, our lineup isn't just the industry's broadest.
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 purpose of this research was to evaluate the production rate (PR) and cutting performance of surface miners (SM) based on rock properties and specific energy (SE). We use data from equipment manufacturers and experimental data in this study and propose a new method and equations to determine both the PR and the cutting speed of SM. The unconfined compressive strength (UCS) of …
Mar 13, 2012· Selective mining of coalCoal seams are often contaminated by undesired waste material.When mining by conventional methods, these waste materials arealso claimed and mixed with the coal, reducing its thermal energy.Processing and cleaning the contaminated coal increases theoperational costs and reduces the overall profits.Using the Surface Miner ...
Cutting drum rotates either in up cutting direction (Wirtgen surface miner) or in complimentary direction (Vermeer surface miner). Surface miner is a compact equipment, which cuts, crushes and loaded the material simultaneously and thus, achieves the advantages of continuous mining system.
Maximum performance in large-scale opencast mining. The surface miner with the highest production rates when it comes to the selective mining of hard or soft rock. The 4.20 m cutting drum unit – tailored precisely to the specified application – with a cutting depth of 650 mm in hard rock guarantees high production rates with minimum tool wear.
Major potentials for cost reduction can be realized as surface miners cut, crush and load the material in a single working pass. The use of primary crushers, for example, is thus eliminated. The use of surface miners cuts the overall investment costs in opencast mining equipment required for iron ore mining by nearly fifty percent.
Maximum performance in soft rock. The surface miner is equipped with a 3.80 m cutting drum unit optimized for use in soft rock impresses with higher production rates and lower diesel consumption. Three material discharge openings in the scraper plate enable to deposit large amounts of cut rock using the windrowing method.
