A new approach to monitoring in the advanced dispatching system for coal mines

Monitoring and supervision systems based on binary signals (machine operation/standstill), which are currently in common use in Polish coal mines, are insufficient for management needs. Machine diagnostics and facility management require continuous checking of the load parameters of longwall complexes, mining machines, haulage lines and the power supply conditions of machines. The visualization of the state of an object as complex as a mine must be uniform, fast and synchronized, forming the basis for selective, easy data access. For almost 30 years, the EMAG Centre has been developing and supplying dispatching systems to coal mines. This paper deals with how the development of computer-based systems proceed. The function and features of the new dispatching system SD2000 are described. Coal mine monitoring levels and applied web, Internet and intranet technology are presented.
