Machines and the Coal Miner's Work The introduction of mining machinery powered by electricity or compressed air changed the way coal miners worked. These pages show mining machines, and offer some information about the introduction of machinery into mining.
Tools of the Trade. This part of the collection covers a whole range of objects, from small gas detectors to large industrial machines, which were used both above and below ground in the coal mining industry. The collection is particularly strong in twentieth century coal cutting machines, rescue equipment, surveying equipment and miners' lamps.
One of the methods used in underground mining is called room and pillar, and is often used for mining coal. Part of the mine is open to the surface and part of it is underground. The coal face is dug out, but pillars of coal are left behind to keep the tunnels open and support the roof. Machines called continuous miners are used to remove the coal.
Minerals and mineral products are the backbone of most industries. Coal is an organic sediment consisting of a complex mixture of substances. It has a lot of commercial and industrial applications. It is an energy giving nonrenewable source of energy. Mining of coal is one of the oldest industrial operation.
Some of the major mining equipment brands on the market include JMC DSK, JOY, DBT, Eickhoff, JMC, i, Tiandi, ZMJ and LMJ coal machine amongst others. It's also important to note that the types of the miner may also play a significant part while selecting the type of mining cutting tool to use.
Coal Mining. Once coal has been uncovered by either an excavator or dragline, an excavator and truck combination are used to mine the coal. To ensure coal is mined optimally as well as accurate reconciliations, surveyors complete a pickup of both the top of the coal (roof) and once removed, the bottom of the coal (floor).
Over the past 250 hundred years, the coal mining industry has witnessed significant changes to both its mining techniques and the equipment used throughout the mining process. Changes evolved through a need to make a safer underground environment for the thousands of miners employed in Cape Breton's coal .
characteristics of the coal. The three surface mining techniques most widely used in the West are area strip, open pit, and terrace pit. Area Strip Area strip is the principal surface mining technique used in the United States. The technique was perfected in the coalfields of Illinois, Indiana, Kentucky, and Ohio. The

Longwall mining is a highly productive underground coal mining technique. Longwall mining machines consist of multiple coal shearers mounted on a series of selfadvancing hydraulic ceiling supports. The entire process is mechanized. Longwall mining machines are about 800 feet (240 meters) in width and 5 to 10 feet ( to 3 meters) tall.
