It was invented by a German submariner in the 1940's and was intended to be used aboard submarines in the event of a fire producing a high content of CO, it was not introduced into coal mining in Britain until the 1960's and had it been introduced sooner would no doubt have saved lives. Hopcalite is the chemical constituent that turns CO into CO2 which can be respirated, the average self rescuer will last for approximately an hour, allowing egress from a potentially dangerous mining environment after a fire where a high concentration of CO is present.

The two types of mining are Open-cast mining and Underground mining. Underground mining is further divided in to Adit mining and Shaft mining.
Self-cleaning windows were invented by PPG Industries.
This article is about coal-mining region in northeastern Pennsylvania. For coal-mining regions in general, see coal-mining region.Counties of the Coal Region of Pennsylvania, known for anthracite mining.Anthracite Coal fields of PennsylvaniaThe Coal Region is a historically important coal-mining area in Northeastern Pennsylvania in the central Appalachian Mountains, comprisingLackawanna, Luzerne, Columbia, Carbon, Schuylkill, Northumberland, and the extreme northeast corner of Dauphin counties. Academics have made the distinction North Anthracite Coal Field and South Anthracite Coal Field (each of Pennsylvania),[1]the lower region bearing the further classification Anthracite Uplands[2]in physical geology.The region's combined population was 890,121 people as of the 2010 census. Many of the place names in the region are from the Delaware Indians (the self-named Lenape peoples) and the powerful Susquehannock nation, an Iroquoian people who dominated the Susquehanna valley in the 16th and 17th-century when Dutch, Swedish and French migrants were exploring North America and founding settlements along the Atlantic Seaboard.The Coal region or Pennsylvania Anthracite region or fields is home to the largest known deposits of anthracite coal found in the Americas, with an estimated reserve of seven billion short tons.[3]It is these deposits that provide the region with its nickname. The discovery of anthracite coal was first made in the Schuylkill County by a hunter in 1791, 16 years after the North Field saw its first mine.
