    Attention!!:
    On 25th July 2001, the MIVENA program was revised to correct some bugs and data file structure change which was being experienced.

    Consequently, the user is hereby being requested to replace the old program by the following new one:

  • MIVENA(Ver6.2c) for Win95/98/NT Version(zip,0.6MB)


    The brief manual for Ver.6 in HTML has been distributed from June 25, 2001.


    The ventilation simulator named MIVENA which was developed in 1986 run on the Microsoft Windows95a/95b/98/NT3.51(SP5)/NT4(SP3).
    The MIVENA system consists of not only the analytical calculation systems, but also the RDBMS, the 2D/3D graphic system, the CAD system for deformed network skeleton and air-conditioning design system.
    The "Skyline Nodal Pressure Method", used in MIVENA, has been successfully applied to the network flow analysis scheme.
    The 21,000 lines comprised in the MIVENA program were originally written in MS Visual BASIC Ver. 5(TM) and Visual C++ Ver. 2(TM) (Open-GL script was partly used for the 3D graphic).

    System Block Diagram of MIVENA Program

    The main functions of the MIVENA program are as follows:
    1)The installed strong analytical system for airflow rate and climate.
    2)The input and output data forms designed in consistence with Windows applications, such as work-sheet data, text, HPGLTM, Image pictures registered to the node/airway.
    3)The RDBMS designed to have some convenient functions used to delete or add nodes and airways automatically by the original functions express the connections of nodes.
    4)The RDBMS also has advantages to set up a data-base to describe the mine layout and solve network airflows for ventilation planning and design.
    5)The computer aided air-conditioning(cooling and heating) system developed to estimate airflow climate by using a psychrometric system.
    6)The psychrometric chart presented on basis of the accurate equations for air conditions applicable to a very deep underground mine. The ranges of pressure, temperature and humidity may be specified by users.

  • Estimate System for Network Airflow Climate

    MIVENA has a computer aided air-conditioning(cooling and heating) system to estimate airflow climate by using a displayed psychrometric chart based on the accurate equations for air conditions applicable to a very deep underground mine.
    The psychrometric chart is available for ranges of pressure, whilst temperature and humidity may be specified by users.
