The Kuzbassrazrezugol Management Company (an enterprise of the UMMC mining complex) summed up the season of operation of concentration plants with steeply inclined separators (SPS). In total, in April-November 2020, almost 2 million tons of coal were extracted from the diluted rock mass at the OS with the KNS of the company, which is 500 thousand tons more than the originally planned volumes.
"The installations of all enterprises of the company, thanks to careful preparation in the off-season period, worked the season steadily and fulfilled the production target exceeding the plan, - says the head of the enrichment department of the Kuzbassrazrezugol Management Company Evgeny Dolgov. “In addition, the weather conditions were favorable this year: in the spring we launched most of the plants in the second decade of April and fulfilled the April plan by 350 percent, and in the fall we continued to work almost until mid-November.”
when using OS with SPS, it ensures maximum reduction of coal losses during stripping operations and does not require large capital and operating costs. The main role in the technology is played by water, with the help of which coal and rock are separated. This is due to the seasonality of the units, the stable operation of which can only be ensured during the season of positive temperatures.
The use of seasonal technology was first tested by Kuzbassrazrezugol Management Company in the early 80s of the last century at the Bachatsky open-pit mine; enrichment plants with SPS - they are used at all branches.
