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

Abstract

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.
