INVESTIGATION OF THE SUSTAINABILITY OF PREPARATORY MINING OPERATIONS
Abstract
The constant increase in the length of supported development mine workings in difficult mining and geological conditions significantly worsens their condition. The failure of the anchor support occurs mainly in workings exposed to the influence of mining operations. Signs of dangerous deformations of the anchor support of mine workings include: breaks and sagging of the lattice or mesh metal tightening between the catches; deformation of the washers at the anchors with a break in their holes; loose or deformed nuts on the anchors; lack of contact of the catches with the roof rocks or coal in the sides of the working, etc.
