Research On The Visualization Technology And Application Of Mining Ventilation Network Information

Safety is the science of studying the whole process of accident incubation and its occurrence,development,elimination and influence.After the proposal of double prevention mechanism,there are clear ways to prevent serious and extraordinary accidents.Information visualization is the foundation of risk classification control of mine,at the same time,it is one of the most fundamental and effective measures to reduce the risk of accidents caused by mine gas grade and spontaneous combustion tendency.This paper has summarized the current research situation of state policies,regulations and visualization,and expounded that the key problem affecting the development of intelligent security management system in our country is Information Island.It also put forward the method of ensuring safety through computer technology-data sharing and collaborative management.In this paper,a mine ventilation network information visualization system was constructed.The data storage and real-time display of the upper computer were discussed in depth.The visualization technology and the mechanism of data Aggregation were presented,which has certain guiding significance for the safety management of coal mine in China.The design of mine ventilation network information visualization system aims at meeting the ability of mine engineers and technicians and protecting user resources maximumiy.On the basis of ventilation system diagram.It is based on Windows,AutoCAD as the development platform,using VBA,VB and SQL server to design visualization system.It includes five parts: human-computer interaction interface,mine ventilation network roadway visualization module,ventilation network calculation module,data storage module and visualization help module.And combining with the field needs,the characteristic information describing the mine ventilation network system was analyzed and the database established.The methods of visualization in different scenarios were put forward: from database to graph and from graph to database query.Finally,InstallShield was used to make installation packages for each module.During the process,the data aggregation mechanism is explored.It is the first time realized real-time data updating and joint processing in different scenarios through nested useing of cursors,stored procedures and triggers.The mine ventilation network information visualization and data aggregation technology were verified,and proves that it meets the needs of on-site work.The system can not only reduce the working intensity of operators,moreover,but the mine management and dispatching command can be completed with a ventilation system diagram.
