Exploitation of Peshelansky gypsum stone mine began in 1933. To-date, a total of 12.5 million tons of gypsum has been quarried.

Over the 75 years of operation, the mine has seen several stages of equipment modernization. Until 1960, most mine operations were based on manual labor. Gypsum rock was shoveled into mine cars which were hauled to the mine shaft by horses and then wound up to the surface by a winch.

Rock loading machines and electric haulage were introduced at the mine in 1961.

The commissioning of a new inclined shaft in 1996 allowed to double the mine’s output.

At present, gypsum stone is mined using modern technology. Cleaned mine roadways are handled by drill rigs. Blasting operations are performed at night using electric fuses. After that, the mine is ventilated by fan units. On the next day, rock loading machines start loading the gypsum stone into mine cars, which are hauled to the mine shaft by diesels and then wound up to the surface by a winch. Then the gypsum stone is delivered to the works by a narrow-gauge railway for processing.

In 2008, a stage-by-stage reconstruction of the mine began to increase gypsum stone output to 500 K and 1 million tons per year.
