The relevance of the work is due to the need to reduce the risk of mortality of miners in case of fire.
The purpose of the work: development of an automation fire-fighting system to ensure the safety of employees of the Third Solikamsk potash-mine administration.
Methodology of the research: solving the problem of analyzing and synthesizing the finite-state automation described by the logical equations of the automated fire-fighting system; software development for the Omron industrial controller. Results. The information about accidents at the Uralkali was analyzed.
The object of research was the fourth mine of the Third Solikamsk potashmine administration. SKRU-3 is one of the three mines in Solikamsk, where the extraction of potassium and magnesium salts is carried out by an underground mining method at a depth of 100 to 500 m. A fatal accident was identified. As a result of smoke generation and fire 9 people died, the builders of the contracting organization, at the fourth mine at a depth of 363 m. The main contract work of the main shaft was performed by employees of the Construction Management No. 30 Federal State Unitary Enterprise from Bashkortostan. When developing a fire-fighting system, a functional scheme for motor control by a drainline pump and a high-pressure fire pump was built, which provides for manual and automatic control of the pumps. It is recommended to install low and high-level sensors and other equipment in the expansion tank and the desalination tank of the drainage pump: pump control sensors, level signaling sensor with remote data transmission. The logical equations and relay contact circuit of the equipment were developed. It is offered the use of software and hardware based on the Omron microcontroller in the engineering section. The simulation modeling of pumps was carried out.
Conclusion. To reduce the risk of mortality and damage to property, a model has been developed for managing the fire-fighting system of the mine management. The principle and relay-contact pump control circuit have been developed. The proposed hardware and software will help prevent alarm conditions and accidents and will increase the safety of the SKRU-3 employees when working in the mine.

Keywords: automatic fire-fighting equipment, relay-contact circuit, mine, microcontroller, occurrence rate of industrial injuries.
