Coals varying in rank from lignite to anthracite were comprehensively characterized with
regard to chemical structure using FTIR and Raman spectroscopy. Structural parameters …

A knowledge of permeability evolution with stress is important for the enhancement of
coalbed methane production. In this study, a series of compaction-permeability tests with in …

Many gas emission accidents have occurred in the Zhaozhuang coal mine in recent years,
so an experiment and simulation study on Zhaozhuang coal adsorption of gas were …

Coal and gas outburst is the most serious dynamic disasters in coal mining. The essence of
mechanics is the instability and destruction process of coal and rock caused by energy …

Although the total death toll due to various accidents in China's coal mining industry has
declined in recent years, gas accidents in coalmine, which are usually caused by gas …

To accurately predict the risk of coal and gas outbursts under different conditions, an
outburst risk prediction system and risk level indices value system were constructed based …

Coal mines have sudden, usually unexpected expulsions of gas in conjunction with coal into
the mine workings. The gas is mainly consisted of methane making this so-called coal and …

The pore structure of coal reservoirs determines the reserves of coalbed methane, and the
gas permeability determines the level of the production capacity. In this study, the SEM …

To reveal the mechanism of coal and gas outbursts in tectonic regions, a gas-driven multi-
physics coal and gas outbursts experimental apparatus was developed. Based on the …

Gas hazards are still one of the most severe disasters restricting mine safety, and the
occurrence of them is heavily dependent on the storage and transportation of methane in …
