The solution or calculation of the ventilation system consists in establishing the quantitative distribution of air flow, in terms of network elements and the characteristics of depression sources. [1] MODERN METHODS OF RESOLVING VENTILATION NETWORKS The 3D-CANVENT program can simulate ventilation systems in operation, which include parameters such as: air flow rates and their distribution in the system, frictional pressure losses, fan performances, air energy requirements and operating costs both for each mine working taken separately as well as for the entire network. Providing the information that characterizes the ventilation network (resistances or geometric elements) and the location and characteristics of the main fans, 3D - Canvent will provide listings and three-dimensional diagrams of the following ventilation parameters: * Distribution of air flows in the ventilation system; * Frictional pressure losses for each individual mining operation; * Resistances of mine workings; * Parameters of the main fans; * Air energy losses in mining works; * Operating costs of the ventilation system (lei/year - based on energy costs and the yields of the main fans). Other features of the program : compressibility of air flow, color data display, air data types, alternate fan start , variable fan speed, changing fan flow direction, heating and cooling, input of rock temperature, natural ventilation - automatic, distribution prediction, source generation assistance, source concentration generation, diesel particle simulation, recirculation detector, analysis predictor network economy, auto simulation, types of files used - SIM, VSM, TXT, importable data - text, DXF, VNE, TPC.
