A set of simulation models of various subsystems of a coal mine was developed with the help of a new visual interactive simulation system of technological processes. This paper contains a brief description of this simulation system and its possibilities. The main possibilities provided by the simulation system are: the quick construction of models from library elements, 3D representation, and the communication of models with actual control systems. These simulation models were developed for the simulation of various subsystems of a coal mine: underground conveyor network subsystems, pumping subsystems and coal face subsystems. These simulation models were developed with the goal to be used as a quality and reliability assurance tool for new process control systems in coal mining.

Abstract This paper looks at the heavy-haul combined train composed of different types of locomotives and its distributed power control system with a combination of 800 MHz and TD-LTE wireless communication. It analyses some key characteristic parameters that affect the synchronism and communication of the differential wireless multi-traction synchronous control systems for heavy-haul combined trains. At the same time, in order to reduce the latency of instruction and information transfer between different types of locomotives, improve the time-limit certainty of wireless transmission and optimize the control quality of multi-traction control systems for heavy-haul combined trains, a synchronism optimization strategy based on the Markov decision process on the basis of Petri networkconstruction is proposed. Relevant experiments and tests are carried out to verify the effectiveness of the synchronism optimization of the control system, which provides a guarantee for improving the differential wireless multi-traction synchronous control system for combined trains and optimizing train control.
