Mining theCoal.Coal minersuse giant machines to removecoalfrom the ground. They use twomethods: surface or underground mining. Many U.S.coal bedsare very near the ground’s surface, and about two-thirds ofcoal productioncomes from surface mines. Modern miningmethodsallow us to easily reach most of ourcoalreserves.

The FGX coal preparation process is density based. The separating compartment consists of a deck, vibrator, air chamber and hanging mechanism, as shown in Figure 1. A centrifugal fan provides air that passes through the perforated deck at a rate sufficient to transport and fluidize the particles. Riffles located on the deck direct material toward the back plate.

The U.S.coalindustry serves a vital role in the nation’s economy by producing fuel for more than half of its electricity. Despite the industry’s importance, industry financial data for 2005—the strongest year for thecoalindustry in recent years—shows that it is a relatively small industry with revenues totaling $20 billion to $25 billion and net income between $1 billion and $2 ...

Predating the development of pulverizedcoalfiring came the development of pulverizers used in theprocessingof minerals. In preparingcoal, or other materials, in sizes approximating talcum powder or finer (e.g.,coalproduced at >70% < 200 mesh and <0.5% > 50 mesh), two fundamentalmethodsapply: impaction and attrition [13].
