Coal is a critical resource for both our community and our country. The U.S. Energy Information Agency predicts that coal-fired energy will continue to be the largest source of U.S. electricity through 2035. At Sunrise, we work day and night to harness this essential natural resource using modern coal mining methods that are both high-tech and safe.
Solution mining includes both borehole mining, such as the methods used to extrac t sodium chloride or sulfur,and leaching, either through drillholes or in dumps or heap s on the surface. 2
Coal is mined by two methods: s urface or ‘opencast’ mining or underground or ‘deep’ mining. The choice of mining method largely depends on the geology of the coal deposit. Underground mining currently accounts for a bigger share of world coal production than opencast; although in several important coal producing countries surface

Coal mining . Some coal mining began before 1900, but the most productive coal mining techniques didn’t develop until after the turn of the century, including the first conveyor belt and mechanized coal loading. Bituminous coal overtook anthracite in the mid-1800s. In the 1960s, smaller coal companies merged into larger, more diversified firms.
INTRODUCTION TO MINING that can be utilized as fuels,such as coal,petroleum,natural gas,coalbed methane,gilsonite,and tar sands. To understand modern mining practices,it is useful to trace the evolution of mining technology,which(as pointed out earlier in this chapter)
The underground mining methods we use include room and pillar, narrow vein stoping and large-scale mechanised mining. Room and pillar mining is a style of mining where tunnels are driven in a chess board pattern with massive square pillars between them which are gradually cut away as the work proceeds. We use this for mining coal.
