Research On The Basic Data Acquisition And Network Diagram Optimization Of Mine Ventilation

Mine ventilation is an important part of the mine production.Ventilation safety is directlyrelated to the quality of mine safety in production and economic benefits. At present, animportant issue of mine ventilation safety is the lack of necessary accurate ventilation dataand better font readability diagram of coal ventilation. And accurate data and the readabilityof the high ventilation network diagram will be a ventilation system to assure reliableanalysis.In this paper, based on the study of detailed analysis of the existing mine ventilationcalculation and the corresponding safety software, according to the actual situation of mineand the scarcity of existing ventilation software,proposed the research of mine ventilationbasic data computation. The goal of the research is that appling the knowledge ofoptimization technique to get complete and accurate mine ventilation basic data.It based ongraph theory and the basic law of airflow in the ventilation network,and used the measureddata in ventilation report forms, establishment of a corresponding mathematical model.Aswell as the software has been developedduring the calculation of the strengths andweaknesses,limitations to do the corresponding analysis of using. Get mine ventilation andaccurate base data from optimization method applied the knowledge. On the basic of theunderlying data, according to the node Pressure, proposed optimization method of networkdiagram. In the network solution based on the proposed two types of roadway on the networkmap on a simplified method.Because the air quantity data of mine is easier to acquire , it raise the method of solvingventilation resistance by air quantity.This methods can take full advantage of the ventilationdata of mine daily management. It can calculate the ventilation resistance and air quantity dataof mine roadway and provide a complete basic data for the ventilation network calculation and the mine safety management. This method not only reduce the workload of mineventilation safety Managers, but also improve the accuracy and compiete of ventilationdata.And proposed network diagram optimization and simplification methods, laid a goodbasic for the calculation and analysis of mine ventilation. In a complex mine ventilationsystem is of great significance.
