The coalbed methane blocks are always structurally and topographically complex, and there
are no models to accurately predict the coalbed methane content in the southern Sichuan …

In the post-extraction epoch, wastewater from mining activities, particularly acid mine
drainage (AMD) residing in sulfur-laden coal terrains, assumes a pivotal role in the safety …

One of the basic tasks of powered roof support is to protect the longwall excavation against
deformation of the rock mass during the underground exploitation of hard coal. The behavior …

In most modern coal mines, there are many coal quality parameters that are measured on
samples taken from boreholes. These data are used to generate spatial models of the coal …

Unusual methane emission and spontaneous combustion of coal induced by the air leakage
are both hazards during mining. The most common practice has been to improve mine …

Underground mining operations are subject to a number of natural hazards. Events resulting
from these hazards are difficult to predict, and if they occur, they disrupt the entire mining …

Coal seam gas is one of the most significant energy resources in unconventional gas fields.
The identification of influenc-ing parameters and methane drainage assessment are, thus, a …

Exploitation practice of Russian coal mines in whole and Kuznetsk Basin especially shows
that safety level of underground mining by gas factor is constantly reduced. The reason of …

The geographical distribution of health outcomes is influenced by socio-economic and
environmental factors operating on different spatial scales. Geographical variations in …
