Surface mining technology hits the mark Today the 4200 SM mines around 2 800 tons of lignite per hour and its 16 m-long conveyor belt discharges the coal in a single pass directly into dumper trucks which then transport the coal to the power station and into the feed hopper
Lignite is more accessible than other types of coal because lignite veins are located relatively near the surface eliminating the need for underground excavation in tunnels Surface mining also eliminates the risk of methane or carbon monoxide buildup a primary safety concern in underground mining Lignite mining is not totally without risk
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
Lignite mining western North Dakota US (c 1945) Lignite is brownish-black in color and has a carbon content around 60–70 percent a high inherent moisture content sometimes as high as 75 percent and an ash content ranging from 6–19 percent compared with 6–12 percent for bituminous coal
The most common exploitation method in PPC's surface lignite mines is the continuous surface mining method (sometimes referred to as the German method or in older references the terrace mining method) using bucket wheel excavators Lignite and waste material are usually transported by conveyor belts while spreaders are used for dumping
