Reservoir properties of Chinese tectonic coal: A review

Fuel, 2020
Abstract Tectonic coal, formed after the intact coal being subjected to long-term intense squeezing, shearing and deformation, is characterised by brittle or ductile damaged coal body, with the characteristics of low cohesion, low strength and low permeability.

Role of Tectonic Coal in Coal and Gas Outburst Behavior During Coal Mining

Rock Mechanics and Rock Engineering, 2019
Coal and gas outbursts are small-scale geological disasters controlled by tectonic movement, and tectonic coal is widespread in outburst zones. In this study, we compare tectonic and intact coal specimens to examine the basic properties of tectonic coal.

Macromolecular response to tectonic deformation in low-rank tectonically deformed coals (TDCs)

Fuel, 2018
Abstract The nano-porous and optical properties of tectonically deformed coals (TDCs) are well characterized while their macromolecular structures have been minimally reported in recent years. In this study, the structural transformations of low-rank TDC macromolecular structures were identified utilizing 13C nuclear magnetic resonance (13C NMR) and ...

The Coal Occurrence Tectonic Units and Coal Controlling Characteristics in Northwest China

Applied Mechanics and Materials, 2013
The coalfield sructure is mainly influenced by the Tethyan Geodynamics system and ancient Asia Geodynamics system in the northwest region, but theres no unified understanding for the coal occurrence tectonic unit yet. Based on the characteristics of coal-bearing strata of the northwest region, the northwest coal occurrence tectonic unit is divided into

A review on pore-fractures in tectonically deformed coals

Fuel, 2020
Abstract Exploitation of coalbed methane (CBM) has dual advantages of not only providing alternative clean-energy but also effectively reducing the proneness for gas outbursts. CBM reservoir properties for tectonically deformed coals (TDCs) differ significantly in comparison to neighboring primary coals, largely attributing to their pore-fracture ...
