MINE WORKINGS SUPPORTING TECHNOLOGIES ON STRESS AND STRAIN STATE CONTROL BASIS

https://doi.org/10.48498/minmag.2023.213.1.004

The development and pilot testing of high-tech resource-saving methods and active means of securing workings and stabilizing the rock mass is still relevant in the coal industry, taking into account the high technical and economic effect and improving the safety of mining operations. To maintain development workings in front of the longwall, accessible domestic technologies are being developed based on the management of the stress-strain state of the near-contour rock mass. This review provides an opportunity to: analysis of the practical use of anchoring and resin fixing compounds in coal mines; study of the parameters of deformation processes in mine workings; establishing the influence of anchoring technology on the operational characteristics of a mine working.
