Quality and Performance of Permitted Explosives and Detonators used in SCCL Mines in India Rajeev Ranjan Singh* CSIR-Central Institute of Mining Fuel Research, India Introduction Permitted explosives and detonators are explosive products which are approved by Directorate General of Mines Safety (DGMS) for use in underground coal mines where there
Jan 29, 2015 The aim of coal quality control in coal mines is to supply power plants daily with extracted raw material within certain coal quality constraints. On the example of a selected part of a lignite deposit, the problem of quality control for the run-of-mine lignite stream is discussed. The main goal is to understand potential fluctuations and deviations from production targets
Coal Exploration and Mining Geology. 2020-8-18 quality guidelines. Alternatively, the program may be required to determine the quantity and quality of coal that may be extracted from a given area, and to identify the geological and environmental factors that may affect mining and use of the identified coal resources.
Jan 06, 2020 In terms of the Elga deposit in South Yakutia, potentiality of increase in completeness and quality of coal extraction based on the studies into structure and contact zones of seams is illustrated. The schemes are proposed for ash content control in coal mining through extraction of dirt and high-ash interbeds of various thickness.
