Development of an automated fire extinguishing system for the mine of the third Solikamsk potash-mine control

The statistics of accidents at the enterprise "Uralkali" is analyzed. The object of the study was the fourth mine of the third Solikamsk potash mine. SKRU-3 is one of three mines in Solikamsk, where the underground method at a depth of 100 to 500 meters is the extraction of potassium and magnesium salts. A fatal accident was identified, as a result of smoke and fire at the fourth mine at a depth of 363 m, 9 people died the builders of the contracting organization. The contract for the construction of the trunk was executed by the employees of FSUE Construction Management No. 30 from Bashkortostan. When developing a fire extinguishing system, a functional scheme for controlling a drainage pump and a high-pressure fire pump was constructed. Logical equations and relay-contact circuit equipment are developed. The design part proposes the use of software and hardware based on the Omron microcontroller.
