COAL GEOLOGY - thecoalforest.tripod

COAL GEOLOGY Written by: W. John Nelson. ORIGIN OF COAL. The geologic story of Mine 25 began about 310 million years ago, during a time known as the Pennsylvanian Period. The landscape and climate of southern Illinois during the Pennsylvanian differed greatly from those of today. At this time Illinois was part of a vast system of deltas that bordered a shallow sea, and the climate was tropical ...

Geologic maps identify coal resources and past .

The maps define the coal geology and coal mining. The locations and areas of past mining are used to estimate remaining coal resources and to assess potential or occurring environmental degradation and mine hazards. In particular, information on underground mines, adits, and shafts helps identify sources of acid mine drainage and causes of land subsidence. Locations of underground-mine ...

Herein, two case studies were conducted where the tensile strength of coal and shear strength of gas hydrate-bearing sediments (GHBS) were predicted using different rock mechanical and geomechanical properties. It is worth noting that in recent years, many studies have reported optimizing the neural networks' structure and estimation capability.

Coal-seam fire - Wikipedia

In the case of near-surface coal seam fires, the influx of oxygen in the air can be interrupted by covering the area or installing gas-tight barriers. Another possibility is to hinder the outflow of combustion gases so that the fire is quenched by its own exhaust fumes. Energy can be removed by cooling, usually by injecting large amounts of water.

Coal: A Lesson in Economic Geology

The microbial activity is directed primarily by the pH of the water. Microbes do their best job at about pH 7. To preserve enough of the material to make good coal, the pH of the swamp has to be at least less than 3 and preferably less than 2, which is often the case. Within the .

Coal petrology and the origin of coal macerals: a way ahead?

Coal petrology, while in many cases may have great utility, can lead to dogma in interpretation, thus slowing progress towards a fuller understanding. The basic language of coal petrology concerns coal macerals. The term Maceral was first introduced by Stopes (1935) in the following way: I now propose the new word ''Maceral'' (from the Latin macerare, to macerate) as a distinctive and ...
