摘要

1.method of evaluation and prediction of stability of rocks, which are engineering geological elements of the potentially hazardous areas in the cat u043eu0440u044bu0445 produce sampling rocks and determine the rheological characteristics of soils, which produce the sustainability of mountain species, u043eu0442u043bu0438u0447u0430 u044eu0449u0438u0439u0441u044f so that, with a view to increasing the efficiency and productivityproduce mechanical u043du0430u0433u0440u0443u0436u0435u043du0438u0435, measure and determine the rheological characteristics of rock samples, at the same time, record the parameters of u0435u0441u0442u0435u0441u0442u0432 u0435u043du043du043eu0433u043e pulse electromagnetic field of the earth (u0435u0438u044du043cu043fu0437) in the immediate vicinity of the test sample are synchronously with the increase of the mechanical loadthe last sample under constant load after each load to achieve a permanent level of registered parameter u0435u0438u044du043cu043fu0437 receive u0433u0440u0430u0444u0438 ci based deformation model and the registered parameter values u0435u0438u044du043cu043fu0437 from mechanical loads determine the thresholds of mechanical stress and deformationthe transition from one stage of hard rock - deformed state in the other stage on the coincidence points u043fu0435u0440u0435u0433u0438u0431u0430 deformation samples. and u044du043au0441u0442u0440u0435u043cu0443u043cu043eu0432 schedules registered parameter u0435u0438u044du043cu043fu0437 produce dimension parameters u0435u0438u044du043cu043fu0437 points of observations within the potentially dangerous areas. u0441u043bu0435u0434u0443u0435u043cu043eu0433u043e of rocks.the counting speed of displacement and the time before the destruction of the mountain u043fu043eu0440u043eu0434.2. method for 1, which, as a registered parameter u0435u0438u044du043cu043fu0437 use frequency of u0438u043cu043fu0443u043bu044cu0441u043eu0432.3. method for ap.1 and 2, and the fact that the measurement of u0435u0438u044du043cu043fu0437 produced in surface observation points located on the square of the rocks. receive cards u0435u0438u044du043cu043fu0437 distribution parameters.to determine the stage of intense - deformed condition and the range of voltages for each point in the rocks of observations by comparing with graphics dependence of the deformation pattern and the registered parameter values u0435u0438u044du043cu043fu0437 from mechanical u043du0430u0433u0440u0443u0437u043au0438.4. method for ap.1 - 3, and the fact that the measurement of u0435u0438u044du043cu043fu0437 produced in u0441u043au0432u0430u0436u0438u043du043du044bu0445 observation points located at a given depth in boreholes, wells on u0442u0435u043du0446u0438u0430u043bu044cu043du043e hazardous sites mountain range, the measurement u0441u043au0432u0430u0436u0438u043du043du044bu0445 observation points are synchronously with the dimensions of the surface points u043du0430u0431u043bu044eu0434 u0435u043du0438u044f,then determine the depth of the zone of maximum concentration of mechanical stress, and the test samples are produced with the loads corresponding to u0433u043bu0443u0431 ine maximum voltage.
