    Transport wody rurociągami szybowymi w instalacjach chłodzenia powietrza w podziemnych wyrobiskach górniczych
    (Wydawnictwa AGH, 2011) Filek, Krzysztof
    A control of thermal hazard in underground mines is connected with cooling equipment utilization, Heat received from cooled air in excavations can be used on a surface. This article applies to problem of warm water transport from mine, with special consideration its pressure and temperature. The algebric equations of pressure distribution were shown and differential equations of temperature distribution in water lines were derived. Two numerical examples, which represented discussed problem, were solved - their results were presented in form of diagrams in two pictures.

    Wpływ źródeł ciepła i wilgoci na stan zamglonego powietrza w podziemnych górniczych wyrobiskach korytarzowych
    (2008) Nowak, Bernard; Filek, Krzysztof; Ptaszyński, Bogusław
    In the article, a matter of haze air flow through horizontal dog heading is discussed. Equations of mathematical description of change the thermodynamic air parameters on the way of flow are given. In this case, appearance of different heat and moisture sources in the heading are taken into account. It was accepted that air can contain a moisture in form of water vapour and fog. For illustrating the discussed problems, the numerical examples for four variants of dates were solved. The results are presented in form of diagram of air temperature variation, its specific and relative humidity and contents of fog in function of running coordinate along the heading axis.
