Abstract

The object of research is the technological processes of the development of deposits and the extraction of solid minerals by underground and open-pit methods. The improvement of technological processes is achieved through the use of existing original technical solutions, which are currently advisable to use in practice. The work is aimed at increasing the efficiency of explosive energy use, improving the technological processes of mining operations in coal mines and open pits of mining enterprises. In the course of the study, an analysis of technical literature on mining topics was used, a search for copyright certificates for inventions and patents on the same topic was carried out. There was a search for innovative solutions that are expedient to apply at the present time. In the course of the analysis, the work shows ideas, methods of coal mining, systems for the development of coal seams, methods of destruction of rocks, microbiological reclamation and other new technologies and devices. The most promising technologies have been proposed for in-depth study, implementation and use in appropriate mining and geological conditions. The proposed technologies, for various reasons, have not yet found wide practical application at mining enterprises. Due to the application of the proposed technical solutions and technologies in practice in the conditions of existing coal mines and open pits, significant economic, environmental and financial effects can be obtained. This study was carried out in order to bring to a wide circle of specialists technical solutions that can contribute to a significant improvement in the technology of mining solid minerals, both in underground and open-pit mining all over the world.

Highlights

With the increase in the depth of mining in the con ditions of coal mines of all countries of the world, the problem of ensuring the operational state of preparatory workings, which depends on a large number of mining and mining technical factors, is becoming more and more difficult

Summary

Introduction

With the increase in the depth of mining in the con ditions of coal mines of all countries of the world, the problem of ensuring the operational state of preparatory workings, which depends on a large number of mining and mining technical factors, is becoming more and more difficult. – significant losses of mineral resources [10,11,12]; – or the tendency of coal to ignite spontaneously [13, 14] In such cases, technologies are used when artificial structures made of wood, concrete, common rocks, and the like are used instead of pillars. It is important to communicate these ideas and proposals to a wide range of scientists, mining engineers and practitioners Their use at the present time would make it possible to improve, as well as significantly improve the technology of mining solid minerals both in open pits and in coal mines. It is relevant to improve the technologies for the development of deposits and the extraction of solid minerals by underground and open-pit methods by applying the existing original technical solu tions, which are currently advisable to use in practice. The aim of research is to analyze, select and substantiate the feasibility of applying in the appropriate mining-geological and mining-technical conditions of the available technical solutions to increase the efficiency of the development of mineral deposits
