Possibilities and Utilization of Software System for Coal Seam Economical Thickness Delimitation Možnosti a Využití Programového Systému pro Vymezování Bilancovaných Poloh V Uhelných Slojích

The article deals with possibilities of utilization of the designed and developed BilPol software system that extremely facilitates, accelerates and specifies the very important initial stage of estimation of coal reserves. The system quickly and transparently compiles and illustrates logs of boreholes and cuttings with indicated seams and benches. In the user-friendly and intuitive graphic environment it provides the user tools for automated search and definition of economical seam parts. In the logs there are indicated in addition segments fulfilling some important criteria e.g. maximum average content of ash as a qualitative parameter of usability conditions. The user application processes data of a coal database containing specifications of layers in boreholes and represents it graphically in a transparent form. The database has been conceived to be generally applicable on all coal deposits in CR. Using the BilPol system it is possible to compile more quickly and more precisely variant 3D models of balance and sub-economical parts of seams for subsequent calculation of coal resources. The system is implemented using the Microsoft Visual Basic language. While creating the program the additional component Microsoft Common Dialog Control 6.0 has been used for creation of the user environment [4]. Access to the database in the MDB format is provided through the Microsoft DAO 3.6 Object Library.
