The Woodville Mine, which eventually covered several hundred acres, had a 90 foot vertical shaft. The bituminous (soft) coal it produced worked well for lights and as fuel to power locomotives and large factory engines. During the early 1860s half of its coal went to Detroit, where its home offices were located.

Mining coal . Coal miners use large machines to remove coal from the earth. Many U.S. coal deposits, called coal beds or seams, are near the earth's surface, while others are deep underground.Modern mining methods allow coal miners to easily reach most of the nation's coal reserves and to produce about three times more coal in one hour than in 1978.

Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams.Coal is mostly carbon with variable amounts of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.

Coal Vertical Roller Mill (VRM) is an air swept, medium-speed, vertical pulverizer with integral classifier. It pulverizes coal by applying hydraulically-loaded grinding pressure through three grinding roller onto a rotating bed of coal. Grinding pressure can be adjusted to account for variations in coal grindability and desired product fineness.
