Purpose. Setting up and implementation of complex, combined and non-waste power-chemical plant based on underground coal gasification with regard to analysis of its technical and economic efficiency. Methods.Research into the reliability of the gasifier plant components was performed by determining the sequence of processes and operations during underground coal gasification technology at all levels of the process.Findings. It was established that high reliability of coal gasification is ensured by stability of all constituents of the technological elements of the process. The basic steps of combining power and chemical plant specializing in synthetic hydrocarbons production are described. During gasifier plant operation, upgrading of equipment at the general level of mechanization between 0.5 -0.7 will not lead to a serious increase in productivity. Therefore, it is necessary to allocate means and efforts to completion of mechanization of all production processes.Originality. The efficiency of mechanization and automation of processes at a gasifier plant is expressed through the formula of automatic control. We have identified dependencies describing changes in the mechanization efficiency of all technological units of the gasifier plant and productivity growth due to reducing the number of manufacturing operations.Practical implications. Analytical research testifies that effective functioning of the gasifier plant is ensured by automation of all technological processes. Computer system conversion requires additional investments which exceed the costs of mechanization by 1.25 -1.4 times.

“…For example, tailings can be used for underground filling, and the waste rock crushed into stone as building materials. Thus, the comprehensive utilization (CU) of mining solid wastes should be considered as the evaluation criterion for GMP [7,21]. Thirdly, gold ore mined by drilling and blasting, emits dust and blasting fumes [22].…”

Green mining (GM) can achieve the harmonious development of mineral resource exploitation and environmental protection. Performance evaluation is the key to promoting GM. This research explores favorable methods to evaluate the green mining performance (GMP) of underground gold mines. First, according to the specific characteristics of underground gold mines, an evaluation criteria system for GM is formulated. Meanwhile, the weights are calculated using an integrated gray DEMATEL and ANP technique, which considers the correlation between indicators. Subsequently, the solution methodology for performance evaluation is proposed based on normalization of indicators. Finally, six underground gold mines are utilized as case studies to verify the methodological feasibility. The results of the empirical study show that there is a significant gap between ordinary mines and pilot green mines, and this study, via comparison analysis and cause–effect analysis, gives direction for mines improvement. Not only will the work provide technical and theoretical support for the evaluation and construction of similar green mines, it will also serve as a reference for government policy implementation.
