Development of automated control systems of sluice gate at mine of second Solikamsky potash-mine department

[摘要] The article analyzes the statistics of accidents at workplaces of PJSC Uralkali. The mine of the second Solikamsk potash-mine department is the object of the research. Analysis of accidents revealed that fatalities were the results of pinching down by the sluice gate. The devices of the gateway door drive and its electric drive control post have been studied. In order to eliminate accidents related to injuries and deaths of people at the sluice gate, an improved ladder diagram has been developed and recommendations for the installation of additional equipment have been worked out. To describe the graph of sluice gate operation, the necessary logical elements are introduced. The graph of states and transitions of cargo gate control is shown. The use of software and hardware based on the OMRON microcontroller is proposed with the development of a ladder diagram for automation of the sluice gate control system. The safety of miners when working in the mine will be improved as a result of its introduction. It is shown that the failure time in the developed ladder diagram to control the sluice gate motor will be significantly less than in the previously existing scheme.
