Air-quality measurements in a deep underground mine are a critical issue. The cost of
ventilation, as well as the geometry of the considered mine, make this process very difficult …

Rock and gas outbursts occur most frequently in coal mining. Gas-induced geodynamic
events in dolomite are a new and unexplored phenomenon. In the last time, two outbursts of …

Rock and gas outburst is one of the most significant natural hazards faced by the mining
industry. In the last decade, this issue has appeared in firm rock mining (including copper …

Among the numerous factors that have an impact on coal permeability, coal porosity is one
of the main parameters. A change in the mechanical stress applied to coal results in a …

In this paper, the problem of transporting rock material deep into the working is addressed.
In the case of coal, literature reports indicate that sorbed gas is responsible for coal mass …

The quality assessment of the air in a deep underground mine is a challenging issue. It is a
time-varying process and it depends on several factors, mainly on technological processes …

In this paper, we present the problem of gas and dolomite outbursts in copper mines. The
energy balance of the phenomenon is analyzed. An examination of the porosity of the …

The analysis of natural hazards, including gas-geodynamic phenomena, requires study of
the basic physical processes that take place at each stage of an event. This paper focuses …

Gas-induced geodynamic phenomena can occur during underground mining operations if
the porous structure of the rock is filled with gas at high pressure. In such cases, the original …

The article discusses the validation process of a certain method of balancing gas contained
in the pore space of rocks. The validation was based upon juxtaposition of the examination …
