Abstract

The article presents a structural scheme for solving the problem of creating a highly effective technology for conducting and supporting preparatory workings, consisting in establishing the laws governing the development of geo mechanical processes for the development of rational technological schemes for conducting mine workings with anchorage. The order of development of technological schemes of carrying out of mine workings with application of an anchor fastening taking into account the intense condition of a file of rocks is generated.

Highlights

Anchor fasteners are used in all countries of the world with a developed mining industry, in France, England, Spain, Kazakhstan, etc
In connection with the complication of mining and geological conditions and increasing the depth of development in the creation of modern technological schemes for conducting mine workings with anchorage, a comprehensive approach combining the study of the stress-strain state of the rock massif and the synthesis of the optimal components of the subsystem "mining and preparatory work" was applied
The experience of using anchor support in France, England, USA, Germany, Japan has shown that the main directions of improving the anchor support are: increasing the bearing capacity of the anchor, reducing the duration of the installation of anchors and reducing the cost of anchorage

Summary

Introduction

Anchor fasteners are used in all countries of the world with a developed mining industry, in France, England, Spain, Kazakhstan, etc. This support is used in a wide range of fastening of preparatory, opening and other excavations. The main task of the anchorage system is to mobilize and preserve the strength inherent in this array, so that it becomes self-sustaining. The mine workings in which the anchor bolt is installed in integration with frame supports are less costly compared to the workings, which are fixed only by frames (Table 1) [1].
