Coal Exploration and Mining Geology - UNESCO

2020-8-18  Coal mining geology activities include delineating in more detail any geological features that may affect the mine layout, such as individual faults and igneous intrusions, as well as monitoring any variations in the seam that may impact on the quality of the coal produced. They are also concerned

2020-12-1  Mining geology: coal rider roof. Coal “riders” are rooted coal beds which occur above (usually within 7 m) principal correlated seams, and generally extend across much smaller areas than the underlying main seam. In some basins, coal riders are common (e.g., Horne et al., 1978a), but in the Desmoinesian of the Illinois Basin they are uncommon.

2021-2-8  From abstract: The mapped area of the Henryetta mining district includes about 168 square miles in Okmulgee County in the east-central part of Oklahoma. The rocks in this district consist of sandstone, silty shale, and shale, and are divided into the Senora formation and the overlying Calvin sandstone of Pennsylvanian age.

Coal Geology - an overview ScienceDirect Topics

Coal-mining safety is a reflection of coal-mining risk and its unique chemical–physical properties as a carbonaceous mineral. Risk has several meanings that are important to coal safety. Risk is both a perception held by every person who works in the industry and a technical concept open to qualitative and quantitative assessment.

Evaluation of Mine Geological Environment of Guqiao

The geological environment is important for the development of coal enterprises. In the Guqiao coalmine, the information of coal mining subsidence, terrain landform, coal gangue utilization, mine water treatment and several on-site investigations have been analyzed. It holds that its geological environment can be evaluated from three aspects, i.e., geological disasters, terrain and landform ...

Trends in underground coal mining in Indiana (1981 ...

During 1979 about 26 million tons of coal was produced in Indiana, 97 percent of which was derived from surface operations. Surface mining has not always played this preeminent role; underground mining was once the major method of coal extraction in the state. Since 40 percent of strippable reserves has already been exploited, surface mining in Indiana is almost certain to decline within a few ...

Drilling into mines for heat: geological synthesis of the ...

2021-7-29  Thermal energy from groundwater in abandoned, flooded, coal mines has the potential to make a significant contribution to decarbonization of heat and net-zero carbon emissions. In Glasgow, UK, a subsurface observatory has been constructed for mine water heat and heat storage research. We synthesize geological and mine water resource findings from a 4 year period of borehole planning,
