11.10 Coal Cleaning 11.10.1 Process Description1-2,9 Coal cleaning is a process by which impurities such as sulfur, ash, and rock are removed from coal to upgrade its value. Coal cleaning processes are categorized as either physical cleaning or chemical cleaning. Physical coal cleaning processes, the mechanical separation of coal from its
Underground coal gasification (UCG) is an industrial process which converts coal into product gas. UCG is an in-situ gasification process, carried out in non-mined coal seams using injection of oxidants and steam. The product gas is brought to the surface through production wells drilled from the surface. The predominant product gases are methane, hydrogen, carbon monoxide and carbon dioxide.
Proper mine dewatering is a critical component to every successful mining operation, regardless of the type of mining that is being done. If the pumps used for dewatering are too small or there is an insufficient number of them, there is a possibility of being flooded out and losing critical equipment and operational time.
Open cut or surface mining in coal is a suitable choice when coal seams are closer to the natural surface. It is an effective method of retrieving a higher proportion of coal when compared to underground mining. The basic process involves: 1) Exploration 2) Geological Modelling 3) Mine Design 4) Top Soil Stripping 5) Drilling & Blasting
Slurry flow in mining-induced overburden fractures is an important theoretical concept for the grouting design of longwall overburden grout injection engineering. In this study, a visual experimental simulation system of longwall overburden grouting was designed to study the flow, pressure distribution, consolidation, and fill thickness of fly ash slurry in overburden bedding separation.
