Coal rank: A classification of coal based on fixed carbon, volatile matter, and heating value of the coal. Coal rank indicates the progressive geological alteration (coal ification) from lignite to anthracite. Coal workers'' pneumoconiosis (CWP): A chronic dust disease of the lung arising from employment in a coal mine.
Basis of Classification 1. Geological consideration Quantum of Exploration Geologic nature (mode of occurrence, shape, depth etc) Common to most system of classification 2. Techno economic consideration Mining Technology Processing technology (emphasis varies on different system of classification)
Health Screening for Coal Miners CWHSP provides coal miners with the opportunity to undergo health screening for respiratory disease with respiratory symptom questionnaires, chest radiography, and spirometry (a type of lung function test) at first entry into coal mining and at intervals thereafter throughout their coal mining careers.

The accurate measurement of vitrinite reflectance (especially for mean maximum vitrinite reflectance, MMVR) is an important issue in the fields of coal mining and processing. However, the application of MMVR has been somewhat hampered by the subjective and the timeconsuming characteristic of manual measurements. Semiautomated methods that are oversimplified might affect the accuracy in ...
Mining influences the quality and quantity of water in the mine area and in its surroundings and changes hydrological and topographical conditions, sometimes drastically. According to the Finnish mine stress test study by Välisaloet al. (2014), water management is at the moment the most challenging stress factor in Finnish mines.
