Ionization waves (strata) in a bounded low-temperature plasma
Radiophysics and Quantum Electronics, 1978Resonant properties of a positive column with excitation of induced strata are considered. The mechanism of steady-state amplitude buildup is established, and the conditions for the soft and hard modes of intrinsic strata excitation are obtained. The conditions under which strata are suppressed when the system is acted upon asynchronously by modulation

Thermophysical properties of coal measure strata under high temperature
Environmental Earth Sciences, 2015Thermophysical properties (such as specific heat capacity, thermal conductivity, and thermal diffusivity) of coal measure strata at a wide range of temperatures are important to coal in situ gasification with environmental treatments. These thermophysical properties have been investigated for different rocks but few are available for the rocks from ...

Solution of temperature field problems in oil strata using integral transforms
Integral Transforms and Special Functions, 2015Heat equations related to some temperature fields in oil strata (such as exact formulation, lumped and the incomplete lumped, and the Lauwerier formulations) are discussed. We survey some oil strata problems and their solutions. The integral transform (Laplace, Hankel, generalized Hankel transforms, etc.) method is used to obtain an analytical solution

A 3D thermal conductivity prediction method for deep strata based on temperature field estimation
Geophysics, 2023ABSTRACT Accurate predictions of earth’s interior thermal conductivity are essential for interpreting the mechanisms involved in geothermal systems and delineating geothermal resource targets. Existing thermal conductivity prediction methods, which typically involve measurements of rock samples and predictions based on geophysical ...

Currently mines of Belaruskali actively expand production capacities in the conditions of great depth of productive strata and high concentration of mining operations. High power loading of mining equipment in combination with complicated geotechnical conditions are the major causes of increased air temperatures in longwalls.

Underground Mine Air and Strata Temperature Change Due to the Use of Refuge Alternatives
Mining, Metallurgy & Exploration, 2019Heat and humidity buildup withn refuge alternatives (RAs) may expose occupants to physiological hazards such as heat stress. The Mine Safety and Health Administration (MSHA) regulations require RAs in underground coal mines to provide a life-sustaining environment for miners trapped underground when escape is impossible.
