Introduction Coal can be regarded for many purposes as consisting of two classes of material: organic components or macerals on one hand, and a range of minerals and other inorganic constituents, broadly referred to as “mineral matter”, on the other.The coal measures are generally shallow, largely unfaulted and lightly inclined, making their exploitation suitable for opencast and mechanised mining. At current rates of production, South Africa has reserves sufficient to satisfy its needs for more than a century.“Coal measure gas,” excluding tight (low-permeability) sandstone gas, refers in this study to the self-sourcing unconventional natural gas stored in coal, shale, and fine siltstone. It is characterized by various types of occurrences and reservoirs, a distinct cyclic succession of coal measure strata, widely distributed mosaic hydrocarbon accumulations, three types of coal measure gas ...Coalbrookdale Coalfield.

It extends from Whitehaven in the south to Maryport and Aspatria in the north. [1]Coal mining operations below the water table of surface and underground mines are common. Therefore, a better understanding of rock behaviour in dry and water-saturated conditions is critical in rock engineering projects. In this paper, Lower Gondwana coal measure rock (sandstone and shale) samples have been collected from 10 different mines (eight collieries) in Jharia and Raniganj coalfield ...The coal-measure formation is rich in unconventional natural gas resources, which is called coal-measure gas, including coalbed methane in coal reservoirs, tight sandstone gas in sandstone reservoirs, and shale gas in shale reservoirs [1,2].Coal-measure gas development has attracted global attention because of its huge resource potential, especially in China [1,3,4].The Newcastle Coal Measures was deposited in a north-south half-graben about 50 km wide, situated between the synsedimentary Lochinvar Anticline (Herbert, 1993) and the Offshore Uplift Bradley, 1993a, Bradley, 1993b.The western part of this half-graben is preserved on the Central Coast where the coal measures thicken eastwards into the Macquarie Syncline and thin westwards onto the formerly ...UK Coal Measures cleat formation is primarily controlled by tectonism following uplift and release of overburden pressure (Rippon, 1996). Variscan tectonics of the late Carboniferous and early Permian deformed the Coal Measures of Northumberland into gentle folds and extensive faulting (Arthurton et al., 1989; Rippon, 1998; Stone et al., 2010).Coal measure gas refers to the unconventional natural gas in the coal system, mainly including coalbed methane, shale gas, and tight gas. Effective utilization of coal measure gas is important for energy supplementation, which has received extensive attention [1,2,3,4].In recent years, due to continuous exploration and development, trail tests and commercial productions of coal measure gas ...Coal measure resources, including aggregated or dispersed solids, liquid and gaseous multitype energies, and metal as well as nonmetallic minerals, are the products of multisphere interaction and metallogenetic materials generation, migration, and accumulation.In order to ascertain the kaolinite crystallinity of Carboniferous Permian coal-measure kaolinite rocks, seven groups of fresh samples were collected from below the ground in the Xiaoyu mine, Datong coalfield.

The coals become thicker toward the center of the basin. The thickness of the black mudstones and carbonaceous shales (Huang et al., 1990) is from 10 to 120 m, but mostly 10-50 m and the mudstones also become thicker toward the center of the basin.

For tight sandstones in coal measures, the source rock is the coal, mudstone, or shale, which is deposited in the environment far away from deep water and is rich in type III kerogen. After being heated by geothermal energy, a significant amount of oil and gas was produced from type I and type II kerogen, while only gas was produced from type ...The coal-derived gas in C-P coal measures, occurs in the widely distributed coal seams of Taiyuan (C 3 t) and Shanxi formations (P 1 s) and tight Xiashihezi Formation sandstones (P 1 x).
