Simulation of the design activity diversification of innovative enterprise
Incoming article date: 24.08.2015The aim of the research was to develop a combined lining that would ensure long-term operation of underground workings in the chemical attack and high pressure groundwater. The problem of protection of groundwater is of particular importance for the mountain enterprises engaged in production of potash. Over the past 100 years in the world (Germany, Canada, Russia, and others.) Were flooded, more than 80 potash mines, including in Russia - mines BKRU-3 (1986) and BKRU-1 (2006) Verkhnekamskoye occurrence. The most commonly used lining of iron tubing does not provide the desired water resistance and durability. Disadvantages of steel lining supports identified based on the analysis of the experience of their application in Russia and abroad. The authors proposed a combination lining which consists of several layers of concrete or reinforced concrete and a waterproof layer of fiberglass. High strength, resistance to aggressive environments, the ability to provide complete waterproofing under relatively high cost of determining the benefits of the proposed lining. Calculations have shown that under certain conditions, the proposed construction of lining can effectively replace expensive cast-iron lining and steel lining.
