Abstract:
In this paper, various technical methods, results analysis and common measuring instruments and equipment for measuring the ventilation resistance of mines are introduced. The advantages and disadvantages of various measuring methods, the applicable mine conditions, the technical characteristics of commonly used measuring instruments and the calculation of measurement results are analyzed in detail. Aiming at the problems existing in the base point method of barometer, the corresponding countermeasures are proposed. The theoretical progress made of equal volume hole failure is summarized. The technical principle and characteristics of the newly developed digital intelligent ventilation measuring instrument in the market are introduced. Finally, the intelligent and interconnected ventilation parameters measuring instruments in China are prospected.
