This report demonstrates the advantages of the roof support bolting technology designed by the Polyakov Institute of Geotechnical Mechanics of NAS of Ukraine. A concept of stability control in the tunnels which uses a structure consisting of rock-anchor elements with a great safety factor is proposed. The new technology is tested and broadly implemented in Ukrainian coal mines.
