Abstract
For machines working in an integrated way, as is the case of automated mining systems, the challenge is to design the control system to ensure implementation of all the functions required both for individual machines and ensure their proper interaction. While the requirements for machines of a given type are defined in relevant standards, the requirements for the linkage among them within mining systems, controlled in an automatic mode, are not always sufficiently specified in regulations and standard documents. Safety related to the control system of mining systems depends on the proper design of each machine and device, the realisation of technological interlocks and interdependencies among them within the complex, as well as on the proper design of the master control system. The master control systems, using digital transmission, enable a remote parameterisation of the control system, a parameterisation of electrical circuit protection settings and deactivation and activation of any input and output signals that are used in the control algorithm. On the basis of the experience gained during the evaluation of such systems, the principles that should be applied in order to avoid the occurrence of a hazard or risk increase associated with the use of master control systems are briefly discussed. This article reviews currently binding technical requirements for machines and their control systems and indicates a number of issues that should be taken into account in the process of designing control systems in order to ensure the required level of safety while using machines operating in an integrated manner within automated mining systems.
