Abstract:

Purpose. Developing a technology with rope anchors hardening a roof of workings supported with steel-polymeric anchors which will exclude the roof collapse cases in zones of the increased mining pressure.

Methodology.Solving problems is based on systematic analysis and generalization of theoretic and industrial domestic and foreign experience in the field of development of technological schemes of mining roadways in stratified and ore mineral deposits; data modeling of strata pressure allocation, defectiveness and stability of rock massif; analytical researches of efficient application of technological innovations; experiments in real industrial conditions.

Findings. The two-level technology of supporting extraction workings based on accounting geomechanics of stressed-and-strained state of rocks around the workings with determining the optimum parameters of roof bolting depending on the influencing mining technological factors.

Originality of the methods proposed in the work consists in the following:

- the design capability to perceive loading without delays, a great load bearing capacity, prevention of the shift and stratification of the roof rocks, formation of domes and rock inrushes;

- reducing methane gas emission into the working, enhanced durability of the support and increased between-repairs resource, as well as the reached economic efficiency due to the cost reduction for working support and repair.

Practical value. Depending on the characteristic of the roof rocks, a way of supporting the roof rocks is developed with an anchor bridge.
