By developing an open pit mining system that capitalizes on the versatility and mobility of wheel and track loaders and capacity-matched trucks, Turkey's Krolin Madencilik coal mine in the Soma area north of Izmir produces an average 125,000 metric tons per month. It is now Turkey's largest independent coal company, and is on the way to becoming the nation's largest single producer of brown coal. Of Turkey's annual 18,000,000 ton coal production, 10,000,000 tons are brown lignite, and Krolin Madencilik's 1,500,000 tons are 15 percent of this production. Management seeks to avoid an equipment imbalance where either loaders or trucks stand idle. As shot overburden nears exhaustion, loaders and trucks progressively move to a newly-shot face in another area of the pit. The mine, 1,960 kilometers north of Izmir, opened in 1956. The moderate to high-grade lignite coal seam (3,000 to 6,000 kilocalories, 10 to 25 percent ash, 1 percent sulphur) is 20 meters thick and overlain by 100 meters of tight overburden. Stripping ratio since 1965 ranges between l : 3 and 1 : 5. It will remain in this range through the life of the 100,000,000-ton deposit.
