Thermal maturity of organic matter Info Shale shale

Crude oil and natural gas are formed in source rocks which contain a required quantity of organic matterShale rock is the best example of a source rock In order for crude oil biogenic or thermogenic gas to be generated organic matter contained in the shale rock must be first processed by specific groups of bacteria or buried deep enough and heated so as to reach thermal maturity that is...

How Does Limestone Rock Dust Prevent Coal Dust

stone If an explosion should occur the rock dust disperses mixes with the coal dust and prevents fl ame propagation by acting as a thermal inhibitor or heat sink To investigate this process in more detail a number of ex 173 plosion experiments using various coal dust and limestone rock dust mixes have been carried out at the Lake Lynn...
