RESEARCH ON THE TECHNOLOGY OF FASTENING MINING DEVELOPMENT WORKINGS OF THE ZHEZKAZGAN DEPOSIT

This article presents the results of a comprehensive scientific and technological study of fastening mining development workings.

The main goal of the study was to substantiate and develop proposals for resource-reducing technology for fastening mine development workings, the costs of fastening and re-fastening of which constitute a significant part of the total cost of work.

The research was based on an analysis of full-scale underground observations of the technology of reinforced concrete anchoring and shotcrete fastening of mine development workings.

As part of the study, an analysis of the condition of the roof of mine development workings and the existing technology of combined fastening showed that in a number of mining and geological conditions during underground mining, shotcrete fastening based on modern filler compositions is sufficient.

 The article substantiates resource-reducing mining and technological solutions based on modern developments and compositions of shotcrete fastening.
