2011-11-9An important but often overlooked source of information is data from the mining industry including subsurface maps, coal characteristics, and mining corehole data. These data can be used to identify coals and shales with sufficient thermal maturity, organic richness, thickness, depth, and areal extent to be a potential reservoir.
Oil Shale Activity in China. shale oil, operated with 120 Fushun retorts. Each retort has the daily processing capacity of 100 t oil shale.. In Fushun, oil shale is the byproduct of coal mining.
Weak shale mine roofs. ... Draw rock or miners slate is the rock immediately above coal beds which must be removed along with the coal bed during underground mining. In western Kentucky, coalbeds of the Carbondale Formation, commonly have black shale roofs. The black shale above the Springfield W. Ky. No. 9 coal is called the Turner ...

Shale gas extraction introduces a host of new water quality issues to a region already compromised by active and legacy coal mining. Greene County is the fourth highest producing county of shale gas natural gas obtained from shale formations in PA.
2017-8-29Marcellus shale, there are high potentials for wellbore instability problems when wells are located in longwall mining areas, which in many areas such as southwest Pennsylvania, West Virginia, and eastern Ohio are being used for extraction of the coal seam overlaying the gas reserves. The ground deformation, caused by coal mining,

Those statements didnt ease the fears of those in the audience. One resident asked that a moratorium be placed or mining applications be suspended until the legislature and science figure out the dangers associated with a combination of coal mining and shale gas drilling.
2019-11-30Coal mining - Coal mining - Coal deposits In geologic terms, coal is a sedimentary rock containing a mixture of constituents, mostly of vegetal origin. Vegetal matter is composed mainly of carbon, hydrogen, oxygen, nitrogen, sulfur, and some inorganic mineral elements. When this material decays under water, in the absence of oxygen, the carbon content increases.
The roller crusher has widely application in the industries of mining, building materials, chemical industry, metallurgy, etc. The roller crusher can crush materials with middle hardness or less than middle hardness into secondary or fine granularity, such as crushing mineral, rocks, coke, coal
Wits-CT tests This test was developed because the Wits-Ehac Index failed to provide results during the testing of some coal-shale samples because of their low liability towards spontaneous combustion. This test involves chemical reactions between coal and coal-shale and oxygen Onifade et al. 2018a.
2012-5-3Shale Gas vs. Coal A comparison of the environmental impacts of shale gas, conventional gas and coal deployment on air, water, and land in the United States. Steffen Jenner a, Alberto J. Lamadrid b a Harvard University, 72 Kirkland Street, Cambridge,
Section 2 showed that a shift from coal to shale gas would also benefit public health, the safety of workers, local environmental protection, water consumption, and the land surface. Most likely, shale gas also comes with a smaller GHG footprint than coal. However, shale gas extraction can affect water safety.
The findings indicated that coal-shale with high carbon contents demonstrated a high liability index. Coal-shale SJ with the lowest hydrogen and nitrogen and highest ash content has a low liability index toward spontaneous combustion. It was found that coal-shale with a high hydrogen and nitrogen content are more liable to spontaneous combustion.

2017-7-5Lawson reported, to the Governor, finding a three-foot seam of coal. Kerosene shale looks like coal, but is much lighter in weight. It can be black or dark green in colour, has a silky sheen and is greasy to the touch. It consists of bituminised mud or clay, whilst coal is carbonised plant tissue.
2018-1-4A. Abutment - In coal mining, 1 the weight of the rocks above a narrow roadway is transferred to the solid coal along the sides, which act as abutments of the arch of strata spanning the roadway and 2 the weight of the rocks over a longwall face is transferred to the front abutment, that is, the solid coal ahead of the face and the back abutment, that is, the settled packs behind the face.
