What are the types of coal? US Geological Survey

There are four major types (or “ranks”) of coal Rank refers to steps in a slow, natural process called “coalification,” during which buried plant matter changes into an ever denser, drier, more carbonrich, and harder material The four 52 Coal Mine Roof Rating (CMRR) Molinda and Mark (1994) have developed the Coal Mine Roof Rating (CMRR) classification system to quantify descriptive geological information for use in coal mine design and roof support selection This system results from years of geologic ground control research in longwall mines in the United StatesChapter 50 Evaluation of geotechnical classification techniques 2021年3月16日  Rockbursts represent hazardous dynamic disasters for underground coal mines and other underground rock engineering projects Some bursting liability indices are put forward and applied to identify the likelihood of rock burst occurrence The classification criteria of the bursting liability indices are proved to be reasonable for coals, but they are still immature for Differences of Mechanical Parameters and Rockburst Tendency 2012 Rock mass classification systems are extensively used in rock engineering design work, and mine design is no exception Among the systems most widely used for miningrelated design work are the NGI Qsystem (Barton et al, 1974), the RMR system (Bieniawski, 1976), the MRMR system (Laubscher and Taylor, 1976) and, more recently, the GSI system (Hoek et al, 1998)The application of rock mass classification principles to coal mine
