Solving The System Of Mine Ventilation Network Based On Three-dimensional Conditions

This paper, based on detailed analysis of the research of existing mine ventilation network solution software and application status, according to the actual needs of ventilation designing, the new trend of ventilation system management towards specialization, computerization and visualization, for the limitation of existing mine ventilation software, proposes a issue based on research and development of mine ventilation network solution system with the three-dimensional technology.The paper breaks the traditional way of thinking about ventilation system design and ventilation network solution software designing, combines with an idea with the core of the air volume needed in the working face and air controlling and makes use of reverse thinking way. First of all, a three-dimensional model of ventilation system is built with a software named 3DMine and the wind resistance of every branch tunnel is calculated; And then, the nodes and branches of the tunnels are automatically marked with the development program, basic data for the ventilation network solution is extracted and processed; Finally, the basic data is substituted into mine ventilation network solution program for calculating and the results storage into the database for easy outputting.The purpose of researching and development, closely integrated with the 3DMine software, is to develop mine ventilation network solution and optimization software based on the three-dimensional visualization platform and for multi-ventilator and multi-stage fan station ventilation station and to lay the foundation of achieving visualization for the future three-dimensional ventilation network solution.Using Visual Basic 2005 as the system development tool, according to the data structure form of 3DMine software, background database of is built with SQL Server 2005. Combined with multi-ventilator and multi-stage fan station network solution arithmetic theory, and part of the arithmetic improved, and the research and development of "mine ventilation network solution system (MVNSS)" are ultimately completed.For the case of "redesigning of ventilation system of old factory of tin mine in Yunnan", the system is verified and the solving results are analyzed and measured, indicating that MVNSS with practicality is scientific and reliable for the mine ventilation network solution.
