Method for control of stability of inner dump includes laying working indicators of special survey stations that consist of profile lines, placement of working indicators, determination of controlled critical values and current for determination of distortion of stability of dump. Before filling dump along design boundary of that one with side of pit at section of filling one performs laying of working indicators that are at same time support ones, as metal waveguides with different length of lower and upper ones, on surface of slant of pit side at cross direction to its propagation. One performs respectively reception of signals of acoustic emission, registration of frequency of arrival of pulses of acoustic emission with determination of controlled critical values of frequencies in course of process of compacting dump mass till its completion. By determined current values to critical values of those one makes conclusions on beginning of formation of prism of possible shift or non-stable state of formed cut of controlled section of inner dump. After that works on dump formation at that section are temporarily terminated. After stabilization of distorted prism of possible shift of controlled section of inner dump that is supported by results of reception of signals of acoustic emission one makes decision on continuation of works of dump formation. |
