EXPERIENCE OF USING GPR IN THE MINE KOTINSKAJA TO ASSESS CONDITION OF PREPARATORY MINE WORKINGS
The substantiation of the need to monitor the condition of the preparatory mine workings fixed roof bolting for the safety of mining operations. It is shown that the currently applied control methods does not give a comprehensive assessment throughout the mine workings. GPR is proposed to use the method to identify dangerous areas that are prone to deformation and collapse. The data mining and geological forecast lava 5210 Kotinskaja mine, taking into account that a schedule of surveys and identified areas of mining. Shows the algorithm for processing GPR data. Are shown the radargram mines with a different state of roof bolting, confirmed in most cases by visual observation. The necessity of accumulating a significant amount of experimental data to develop a complete technique of GPR surveys of underground mine workings.
