Economical maintenance of underground haulroads Dinting machine 2600

Minimizing underground transport costs with the dinting machine 2600 The dinting machine’s main fields of application: A – Milling off the uneven floor surfaces produced by drilling and blasting; B – Levelling the ground in case of rutting; C – Milling off ground undulations perpendicular to the travelling lane and D – Increasing the headroom. A C B D Transport outlays often account for the largest single pool of costs for companies mining minerals underground. These costs are composed of a large number of individual items such as fuel, tyres or wearing parts on the axles, chassis or gearbox....

2 // 3 Removing rutting – the main job of the dinting machine 2600 In German potash mines, rutting used to be eliminated by slurrying and compacting fine salt, but these layers were soon destroyed again by the heavy transport vehicles, in particular on ascending slopes. Here, levelling the roads by milling off the floor has proved a highly effective alternative. This method produces a road with good skid resistance in the solid material while increasing the headroom at the same time. This is particularly advantageous in places where ground undulations keep reducing the headroom. The “heart” of...

“Made-to-measure” for working underground The most striking feature of the unit – even in the standard version – is its low overall height of just 1.70 m. A powerful diesel engine drives the milling drum, travel drives and other components. The engine and the hydraulic fluid are kept within an optimum temperature range by an effective cooling unit, which is always designed with a view to the ambient conditions to be expected. The cutting depth of the machine is continuously adjustable up to a maximum depth of 20 cm. An automatic levelling system ensures that the required working depth is maintained...

4 // 5 The special arrangement of the cutting tools on the drum ensures that the milled surface is even and, therefore, conveniently trafficable. Because of the excellent milling results, the investment in the machine will pay off in an extremely short period of time due to savings on operating costs and the increase in productivity. A welcome side effect: the smooth roads make for greater riding comfort for the drivers of all transport vehicles underground. The generously dimensioned cooler keeps all components at an optimum operating temperature. The cabin, which can be supplied with air-conditioning...

Rheinberg Heringen Neuhof Heilbronn Bischofferode Merkers Unterbreitzbach Thirteen dinting machines are currently in operation at nine German mines, some of them since as early as 1989. Their task is to ensure the maintenance and further extension of mining and haulage roads, the networks of which can attain lengths of over 60 km in just one mine.
