Safety requirements for mining systems controlled in automatic mode

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.
