Problems solved by technology
However, since the ventilation system of large and medium mines is a non-linear network fluid network composed of hundreds or even thousands of air channels, it is very complicated and time-consuming to study the relationship between the fan and the air volume of each air channel, and it is difficult to quickly Accurately select the optimal fan that meets the air volume of the air duct

The invention provides a simulation analysis method for a complex mine ventilation network. The simulation analysis method comprises the following steps: forming an original wind network; the original wind net is simplified, and a simplified wind net is generated; a fan characteristic curve of each ventilator is given, the simplified air network is adopted for air distribution calculation to obtain the air volume of each virtual air-using air duct, and the air volume of each virtual air-using air duct is equivalent to the air volume of each actual air-using air duct obtained through air distribution calculation of the original air network. According to the method, the influence of various fan type selection and adjustment schemes on the actual air volume of the air duct for air network simulation can be simplified, and the calculation amount of air network calculation is greatly reduced. The method has great practical value for reducing the workload of ventilation management, reducing the difficulty of air network calculation and simulation analysis, improving the mine ventilation management efficiency and realizing reasonable air supply.
Description
Technical field [0001] The present invention is the field of mine ventilation and safety technology, and it involves an analog analysis method that specifically involves a complex mine ventilation network. Background technique [0002] Mine ventilation is one of the main technical means to ensure the safety of ore.During the production process of the mine, the fresh air on the ground must be continuously transported to various operating locations under the well in the underground to breathe, and dilute and eliminate all kinds of toxic and harmful gases and mining dust in the well.Ensure the physical health and labor of the operators under the well. [0003] The main task of mine ventilation is to choose the appropriate fan based on the temperature, humidity, harmful gases and mineral dust concentrations of the underground, to ensure the quality of the air supply in real time, and meet the wind on time on time on time and the wind in normal and disaster periods. [0004] In existi...
