amounts of coal from more remote locations, coal transportation will become a more important concern from an energy, economic, and environmental stand­ point. Coal can be moved directly by railroad, truck, pipeline, barge or ship; energy obtained from coal can be transported as .

In the working areas, the coal was loaded into mine cars and pulled by mules to the tipple or to the bottom of the shaft or incline for hoisting. Underground, the dip of the coal beds dictated the mining method to be used. In generally flatlying beds, variations of room and pillar mining were used.

Before the advent of largescale mining in Jefferson and Indiana counties, coke was manufactured by burning coal in heaps on the ground in such a way that only the outer layer burned, leaving the interior of the pile in a carbonized state.

Mistakes can be costly—imagine a load of coal dumped in the waste pile! Fortunately, by monitoring material movement and alerting operators and planners to misroutes, surface fleet management technologies help ensure operators use the proper haul routes, identify the correct load and dump locations, and deposit the right material in the right ...

This is a mixture of solid coal containing water and is obtained as a byproduct during mining. The coal particle size is usually less than 1 mm. It is regarded as a cargo that may liquefy due to its high moisture content. This is a mixture of coal and water with the largest coal particles around 7 mm.

Jun 19, 2012· Traditionally, coal mining involved the distinct steps of undercutting the seam, then drilling and blasting the undercut coal into manageable pieces, and finally loading and hauling the coal to the surface. The complexity of these tasks and the tight spaces encountered underground, especially in lowcoal seams, presented difficult challenges for inventors of mine machinery.

Share Joy Loading Machine. By replacing the laborintensive job of handloading coal, the Joy loading machine helped revolutionize mining in the 20th century. When it was introduced in the 1920s, the Joy loader was one of several coalloading machines on the market. The Joy displaced the others because it required less maintenance,...

In areas where coal mining has not been previously practiced, the search process should result in obtaining coal samples that give reasonable evidence of the existence of a coal seam. Once a seam has been discovered, considerable further work is ...

Methods of extraction. Surface mining and deep underground mining are the two basic methods of mining. Seams relatively close to the surface, at depths less than approximately 180ft (50m), are usually surface mined. Coal that occurs at depths of 180 to 300ft (50 to 100 m) are usually deep mined, but in some cases surface mining techniques can be used.
