SELECTING MINING SCENARIO FOR THE MAKARIEVSKY COAL SITE

The article gives geological characteristics of the Makarievsky coal site in Kuzbass and offers mi-

ning scenarios using open pit, underground and hybrid methods. Based on the net profit criterion, it is found that over the period of mining, money flow makes 143.4 billion rubles and net profit totals 20.1 billion rubles. The analysis of money flows and net profits in the alternate scenarios shows that in the open pit and hybrid mining methods, production efficiency is enhanced by 20–30% and mining period is cut down by 15–20 years, while land reclamation using traditional techniques nullifies net profit. Therefore, land reclamation requires hydraulic or mechanical/hydraulic engineering which ensures cost saving by 30–45%.
