Description

The technique of mine surveying observations over the deformation of gateroads in the area of longwall influence is developed. The results of in-situ observations over the deformation of the “support – rock mass” system of gateroads under the influence of extraction works are presented. The approach (based on field observations) to supporting with the cable bolts and forecasting the condition of the gateroads in the area of the influence of extraction works in the conditions of soft rocks is substantiated, which allows to ensure gateroad maintenance and re-use with minimal cross-section losses and repair works. A technique for predicting the convergence of gateroads by a statistical-analytical method is developed.
