In allusion to the failure data submergence in a circuit breaker burning accident in a conventional substation of a coal mine, and in view of those supervision and control system defects in a conventional substation such as information islands, complication of network nodes and subsystems, nonstandardization of application function, poor expansion of system, and also high charge of operating and maintenance,...
As a modern security design, Inherent Safety means that equipment and facilities is able to contain the inherent fundamental features to prevent accidents. Mine hoist is the most important equipment in the coal production. How to achieve safe, reliable, efficient production, has been the focus study at home and abroad. Inherent safety is reflected in hoist design, primarily through the design measures...
The coal enterprise behavior safety integrated management and control system is the integrated management and control information system which takes the behavior safety as the core and aims to guide safe behavior and realize coal safety supervision. In this article, we describe the theoretical base of the system design, i.e. the theoretical frame of the accident prevention and control for coal enterprises...
In order to construct digital coal mine, a three layer model for digital coal mine model is proposed in this paper. Two basic platforms, the uniform transmission network platform and the uniform data warehouse platform, are discussed. A real 1000 M industrial Ethernet transmission platform based on Siemens PROFINET is established for Yangchangwan coal mine. The network platform is an information superhighway...
