The World of Wirtgen Surface Miners - 4

Breaking new ground in the mining of useful minerals Economically efficient open-cast mining of useful minerals is becoming increasingly difficult, because in many existing and also newly developed deposits the amount of useful minerals is falling as a result of complex geology. In rock operations, machines are needed for highly precise levelling work under space-restricted conditions. Our patent remedy in both cases is mechanical exploitation by means of surface mining. This innovative technology takes account of an increasing demand for economically efficient and environmentally gentle...

4 // 5 The method of cutting, crushing and loading in a single working operation is far more effective than conventional methods. Strict environmental regulations for noise and dust emissions make surface mining attractive when compared to conventional drilling and blasting methods. Selectively mined materials increase the exploitation rate of mineral deposits. The stable, even surfaces produced in earthwork and rock operations can be used immediately as roads, embankments or tunnel floors. Success in a single step The method is excellently suited for the selective mining of thin,...

The World of Wirtgen Surface Miners - 6

Cutting, crushing and loading in one working operation Drilling and blasting in mining, earthwork and rock operations are, quite simply, no longer “state of the art”. Surface mining offers a far more economically efficient and environmentally friendly solution, as it is capable of cutting, crushing and loading rock in one single working pass. The innovative technology cuts expenses for machines and personnel and saves a considerable amount of time when compared to conventional methods. At the same time, it produces even, stable surfaces and embankments, and permits the selective mining of...

6 // 7 Sharply reduced costs for personnel, machines and operation, plus low volumes of overburden are the distinctive features of modern surface mining technology. The selective cutting of rock is gentle on resources while enabling a high yield of minerals of great purity. The cut, even surface forms an ideal subgrade for road pavements, and transport vehicles can use it during the construction period without causing damage. Accelerated approval procedures and reduced times for opening up new deposits are the immediate results of this gentle mining method that does not involve blasting....

The World of Wirtgen Surface Miners - 8

It began with a vision … Why don’t we apply our know-how gained in asphalt milling to the mining of hard rock? In the mid 70s, this idea triggered the development of a new, economically efficient open-cast mining method known as surface mining. What followed was an unparalleled success story, and it was headed by Wirtgen as the driving force behind it right from the start. Following the requirements of the market, we developed ever larger machines for ever higher performance. Other suppliers were unable to gain ground. Being the sole manufacturer of these highly specialized and highly...
