Purpose. An innovative approach formulation to the rational development of potential coal mines expand economic activity mining enterprises based on implementation underground heat generators during gasification. Methods. Based conducted analytical and laboratory research, study possibility introducing cogeneration systems gasification at site its occurrence. The basis for conducting studies is...

Underground coal gasification (UCG) technology converts deep resources into synthesis gas for use in the production of electricity, fuels and chemicals. This study provides an overview systematic methods situ process. Furthermore, model porous structure has been presented movement taking place carbon matrix—which is part bed—has described. The experimental tests were carried out with air forced...

Abstract In this study, the composition of tars collected during a six-day underground coal gasification (UCG) test at experimental mine ‘Barbara’ in Poland 2013 was examined. During test, tar samples were taken every day from liquid product separator and analysed by methods used for testing properties typical coke oven (coal) tar. The obtained results compared with each other data As progresse...

There is a large range of time and length scales of turbulent fluctuations in an entrained flow coal gasifier. To figure out the turbulent effects on coal gasification processes and the controlling mechanisms of different regions in an entrained flow coal gasifier, the characteristic time and length scales for all major processes are estimated.On the basis of the comparisonbetween the length/ti...

Fatal accidents associated with underground coal mines require the implementation of high-level gas monitoring and miner’s localization approaches to promote underground safety and health. This study introduces a real-time monitoring, event-reporting and early-warning platform, based on cluster analysis for outlier detection, spatiotemporal statistical analysis, and an RSS range-based weighted ...
