Methods of diagnosing and monitoring the deployment of simple inclusion in the conduct of breaking in layered rock mass
YU. P. GALCHENKO

Large-scale modernization of the open-cast mining of ore deposits based on the introduction of cyclic-flow technology places new demands on the methods of obtaining timely information on the geological structure and the real anisotropy of physical and mechanical properties of rocks within a single working ledges and blocks slugger. Existing methods for obtaining information on the deployment of lithological differences in such kinds of arrays require any additional exploratory coring, or the use of special geophysical equipment, which significantly increases the costs and complicates the organization of cyclical mining waste water treatment stations. The idea of a fundamentally new method of diagnosing the situation and control the strength of strong seams is to obtain geological information required by the continuous measurement of energy consumption along the length of the drilling blast holes and assessment on this basis, the distribution of the fortress of rocks in the area oburennom working ledge and then adjusting the parameters of its breaking. a special device has been developed, the sensor is included in the circuit composition of the drilling machine, continuously submits to the reader signal, reflecting the power consumed by the motor. Basic laws of breaking rock with a drilling tool movement were based on energy theory Davidenkov-Friedman. Equipment rigs to create a device allows you to get information on the distribution in time and space, the value of the local energy intensity drilling and quickly adjust settings directly in the process of drilling and blasting oburivaniya treatment units.
Keywords: open mining, lithological difference in the rock mass, rock Different Strengths, detection, outlining, the energy intensity of failure, drilling, strong seams, diagnostic technique, control technique of dislocation, the adjustment parameters.
