Broken coal and rock (BCR) are an important component medium of the caving zone in the
goaf (or gob), as well as the main filling material of fault fracture zone and collapse column …

Gas and coal spontaneous combustion (CSC) compound disasters have become a common
mode of serious accidents in coal mines. This study is aimed at revealing the characteristics …

The spontaneous combustion of residual coal and potentially subsequent gas explosions
that occur during gas drainage of the gob were investigated. The 1262 fully-mechanized …

This paper focuses on assessing gas drainage performance from vertical surface goaf holes
in an operating mine with high specific gas emission rates (~ 20 m 3/t). Field monitoring …

Reliable prediction of methane emission sources and dynamics from adjacent strata of
longwall coal mining is critical for develo** efficient methane capture designs to maximise …

Mining is associated with poor safety due to pressure relief gas emission from the goaf
during the production period. The aim of this study was to explore a case study of the …

There are abundant coalbed methane (CBM) resources in abandoned coal mines, and the
extraction of CBM from abandoned coal mines has become one of the important CBM …

Longwall coal mines in the Bowen Basin of Australia are highly productive and gassy,
comprising many coal seams above the working seam. Predictive modelling of specific gas …

As intelligent mining operations evolve, stringent standards for gas management and
extraction are imperative. To mitigate the risks associated with coal and gas outburst and to …

To reduce the gas disaster of high gas coal seam and improve the efficiency of gas
extraction by high drilling, the layout parameters of drilling holes in **dingshan coal mine …
