FACTORS OF RESISTANCE AGAINST AIR CURRENT ESTABLISHED BY MEASUREMENT AND FACTOR ESTIMATED BY LITERATURE

Abstract

Specific resistance (R100) for underground mine rooms can he calculated by the constant (C). Constant (C) enables defining of the resistance for any relation of dimensions F3/U in similar mine rooms. Considerable anomalies were found by comparison of the resistance factor calculated from measurement data with estimated value of the factor from specialized literature on planning similar ventilation structures (the paper is published in Croatian).
