The Meco-Moore cutter loader was an early twentieth-century British mining machine. It was invented by Mr M. Moore, and developed by the Mining Engineering Company (MECO) of Worcester.It was a heavy machine (120 hp / 89.5 kW) and was first used in a coal mine in Lancashire, England 1934. The design was such that it worked along the coal seam (along a "longwall panel") The machine's cutter …
This paper proposes a new roadheader-assisted coal cutter (RACC) based on the tensile failure mechanism of coal. An innovative mining method, called the cutting inside and spalling outside mining (CISOM) method, is developed based on this new RACC. The mechanical model is established, and the working mechanism of the new CISOM method is illustrated using a column model and a beam model.

continuous miners in underground mining to the larger than life draglines found in surface mining. Even with some of the most complex equipment in the industry today, mining is still, at its core, a fairly simple process. Specifically, underground coal mining can be broken down into three basic components: mining, transport and removal.

Equipment Cutting Machines - Introduction. There have been several different types of cutting machine developed over the years, but "shearers" and "ploughs" have proved to be the most successful, especially the former and will be the only types dealt with in any detail here. Some types, such as "trepanners" were designed to produce a larger size of coal required for boilers, particularly for ...

Mining Equipment and Inventions. Deenside witnessed Ireland's first steam engine at Doonane Collieries in 1740s. It is mentioned in Tighe's Statistical Survey where he remarks on the efficiancy of Fenlon's Steam Engine. Bill Hoyne pioneered in steam traction with a train of wagons each carrying approximately 10 ton of coal.
Mine Machines, Coal Cutting In the early days of using coal, loose coal would be gathered by hand where coal seams reach the Earth's surface (outcrop). Hand tools such as picks were used to get the coal. As seams were mined underground, sharpened hand tools were the standard equipment and continued to be used in small mines until the 1950s.
Longwall Miner. Twenty percent to 30 percent of mined coal underground is from longwall mining. This is performed by a mechanical cutter that shears coal off from a panel on the seam. The panel being worked on may be up to 800 feet in width and 7,000 feet in length. Mined coal is deposited onto a conveyor that moves the coal to a collection area.
