Coal is NOT classified as a mineral because Miners use earthmoving equipment to dig a huge hole in the process of they are NOT classified as minerals because they are organic When geologists say that a mineral always contains certain elements in definite proportions, they mean that the mineral is a rock forming mineralAccording to Kentucky Coal Education, continuous miners consist of a series of large cutting shearers and a selfraising hydraulic system that supports the mineshaft ceiling as sections of coal are removed Rock Duster Rock dusters are pressurized pieces of equipment that coal miners use to spray inert mineral dust over highly flammable coal dustList of Mining Equipment | Career Trend

Underground Mining Safety Equipment Checklist Grainger
Underground mining operations around the world pose similar risks to worker safety and health Though different techniques are used to extract base metals, precious metals, nonmetallic minerals, diamonds and coal, the hazards do not differ that much The deeper the mine, however, the greater the risk According to the United States DepartmentThe calculation of the performance of coal washing units that are in common use is not difficult and the principles of making such calculations have been known for many years The flowsheets to be simulated consist primarily of coal washing units each with a target specific gravity of separation specified for each washing unit The feed is allocated to each washing unit on theCoal Washing Plant Metallurgist & Mineral Processing
Breathing Easy: Respiratory Protection in Coal Mines | EHS
In the first 2 months of 2006, 16 miners lost their lives working in West Virginia coal mines Since then, unions and organizations advocating for workers' rights have stomped their feet on Capitol Hill, calling for an urgent review of how safety regulations are enforced and whether the personal protective equipment used by miners, including respiratory protection, is adequateAdsorption tests Two coals used for the adsorption tests were from the Upper Freeport and Pittsburgh No 8 seams The raw coals were crushed and screened to the size range of 10+100 mesh, and then mixed with a heavy liquid, 1,1,1trichloroethane with a specific gravity of 133, to reject the majority of coarse size impurities (pyrite and shale minerals) to the sinkUltra Fine Coal Cleaning

How digital innovation can improve mining productivity
With profits down, miners are focused on improving their productivity Digital innovation could provide a breakthrough The global mining industry is under pressure In the short term, falling commodity prices are squeezing cash flow Looking ahead, many existing mines are maturing, resulting in the extraction of lower ore grades and longerStrip mining, removal of soil and rock (overburden) above a layer or seam (particularly coal), followed by the removal of the exposed mineral The common stripmining techniques are classified as area mining or contour mining on the basis of the deposit geometry and type The cycle of operations for both techniques consists of vegetation clearing, soil removal, drillingStrip mining | Britannica
