This annual series of books includes scientific papers on mining profiles. This volume presents multiple aspects of mining technology implementation in several aspects: extraction of coal, iron, manganese, uranium and other ores. Capturing and utilization of coalbed methane by various methods including alternative ones, safety measures in mining, ecological aspects, etc.Specific attention is paid to intensification of mineral resources extraction processes by way of modernizing opening methods, development and mining methods depending on mining-geological conditions. Experimental results of stress-strain state rock massif forecast by means of computational experiments using recursive methods are also discussed. Any mining operations should finally result in adequate recovery of land surface and utilization of mining wastes using various environmentally friendly methods, thus, sufficient attention is paid to this scientific trend. Non-traditional methods of minerals mining are becoming more topical and of higher demand in the modern society. Hence, several papers/chapters are devoted to underground coal gasification and its subsequent processes. In addition, extraction technologies of gas hydrate, as a source of an abundant amount of natural gas, are thoroughly examined in this book, including implementation of gas hydrate technologies for mine methane utilizations with its following transportation in a solid state. Furthermore, attention is given to evaluation of economic efficiency of minerals mining by the proposed methods, their ways of enrichment, ecological aspects and the influence of mining production on the environment, innovational logistic solutions at mining enterprises, and also to perspectives of Ukraine's mining industry integration to the European standards.

ABSTRACT: Technical, economic and environmental efficiency factors were analyzed for application of ERA emulsion explosives containing the solid propellant processing products. Applicability of ERA emulsion explosives for mining enterprises using both underground and surface mining operations was proved.

1 Introduction

Currently in Ukraine, as in other countries with developed mining industry, there is a steady tendency to refuse TNT containing explosives and change to the commercial emulsion explosives (Yefremov 2010, Kholodenko et al. 2014, Stupnik et al. 2013, Khomenko et al. 2013).

The use of emulsion explosives (EE) allows reducing the costs for blasting and enables control and optimization of the parameters of explosion depending on the application. At the same time it provides higher safety of blasting operations and creates favorable conditions for use of effective mechanized transportation and loading of boreholes (Efremov et al. 1996, Stupnik et al. 2013).

Production of emulsion explosives has changed the concept of arrangement and carrying out of blasting in mining enterprises and promoted the development of new types of raw materials and equipment for the production of explosives and loading equipment.
