Description

When we talk about the mining works, which are in such a function, so that air currents pass through such aerodynamic lines, then we are dealing with the need to calculate the aerodynamic resistances in such aeration networks. Ventilation systems, in the broadest practical and technical sense, are nothing but a reflection of the aeration plans of the mine as a whole or of its individual parts in an appropriate schematic manner, which includes only those specific works through which it circulates. air, while other works are excluded. The ventilation network does not fully comply with the mining plans, because the air circulation system does not take into account blind works, preparatory works as well as works or other parts of the mine, which are insulated with doors or ambushes. For the purpose of analysis of the aeration system, calculation of aerodynamic resistances, aeration quantities and depressions of the aeration networks can be presented in the following schematic forms: spatial schemes, linear or orientation schemes, canonical schemes, quantitative schemes, potential schemes. Spatial schemes facilitate the general orientation of the way of mining. The spatial scheme also shows the short connections as well as the transport routes where the ambushes with doors are located. In these schemes the breathing and exhalation well must be clearly presented. The key points (nodes) of the network should be marked with consecutive numbers, starting from the breathing well, while the direction of air movement is marked by arrows. As far as possible, spatial schemes should be built according to the following principles: horizontal works should be presented horizontally; dishenders and bremzbergers appear on the slope 60 0 to the horizon; vertical works (wells, blind wells) must be presented vertically; traverbanks are presented with a slope of 30 0 ; lavat (wide working fronts) usually appear as dishendeite. Usually for complicated aeration networks, orientation for the aeration method of the mine only on the basis of the spatial aeration scheme can be difficult. In such cases the problem is greatly simplified through orientation schemes in which not all aeration routes are presented, but only wells, levels, areas of use as well as other characteristic aeration sites (for example, car rooms, explosives, etc.). .). The canonical schemes aim at a clear reflection of the ventilation system in order to facilitate the analysis and all possible calculations. In these schemes are marked the locations of the fans, possibly their depression, the direction (current) of the currents, the fields of use (workshops), the regulating ambushes, as well as other ambushes or ventilation doors and eventually the resistance of the branches as well as the quantities of the air passing through each branch.

Operational and Statistical Management in Relation to Determination of Aerodinamic Resistance on Mining Lines

When we talk about the mining works, which are in such a function, so that air currents pass through such aerodynamic lines, then we are dealing with the need to calculate the aerodynamic resistances in such aeration networks. Ventilation systems, in the broadest practical and technical sense, are nothing but a reflection of the aeration plans of the mine as a whole or of its individual parts in an appropriate schematic manner, which includes only those specific works through which it circulates. air, while other works are excluded. The ventilation network does not fully comply with the mining plans, because the air circulation system does not take into account blind works, preparatory works as well as works or other parts of the mine, which are insulated with doors or ambushes. For the purpose of analysis of the aeration system, calculation of aerodynamic resistances, aeration quantities and depressions of the aeration networks can be presented in the following schematic forms: spatial schemes, linear or orientation schemes, canonical schemes, quantitative schemes, potential schemes. Spatial schemes facilitate the general orientation of the way of mining. The spatial scheme also shows the short connections as well as the transport routes where the ambushes with doors are located. In these schemes the breathing and exhalation well must be clearly presented. The key points (nodes) of the network should be marked with consecutive numbers, starting from the breathing well, while the direction of air movement is marked by arrows.
