Abstract:

Purpose. Increased resistance of outcrops in production taking into account the ways of development of the effect of the mining-and-geological and mining-and-technical factors of mining operation.

Methodology. There have been applied the following methods: comparative analysis, mathematical modeling and forecasting.

Findings. There have been introduced the results of experimental-industrial works to reduce swelling of the subsoil in different mining operation conditions, observing and monitoring the manifestations of rock pressure, bedrock deformation, the displacement of host rocks on the side of workings and roof. Different types of timbering have been applied considering the complicating factors of mining, taking into account the geomechanical conditions of conducting and maintaining workings. It is recommended to apply a technology to maintain the bedrock that will improve the stability of rock outcrops in the development considering the ways of manifestation of the effect of geological and mining factors of mining.

Originality. An anchoring technology has been worked out aimed at reducing the swelling of the subsoil in different mining conditions, while using different types of timbering considering all the complicating factors of mining, as well as taking into account the geomechanical conditions of operation and maintenance of workings.

Practical value. It is recommended to make an installation of anchors into the soil in advance of the following effect of confounding factors (bearing pressure zone in front of the lava, and others), mainly in the district workings exposed to mining operations (extraction front, overworking and underworking zones, zones with increased rock pressure). It is also recommended to collar the inclined holes under the anchors inclined at an angle 20-40° to the vertical. The length of the holes is calculated considering their technical capability of drilling and is assumed to be 1.6, 2.4 and 2.9 m with a cross installation of the anchors.
