method of controlling and determining the dangerous state of the rock in underground mining work

摘要

the invention relates to a geophysical research of rocks, in particular ways to control and determine the dangerous state of the rocks in the u043fu043eu0434u0437 u0435u043cu043du044bu0445 mining work in which acoustic emissions are man-made source register signals of acoustic emission, cultivating the right u043du043du044bu0435, according to the results of processing are of the dangerous condition of the rocks.and can be used in the mining industry, a lining of tunnels and other underground work. according to the invention as a man-made source using the car makes a. an additional register signals of acoustic emission from natural sources of the rocks.processing of received data is performed using the changes u0444u0440u0430u043au0442u0430u043bu044cu043du043eu0439 dimension of time series of acoustic emission, which determine the u043fu043eu043au0430u0437u0430u0442 picea u0444u0440u0430u043au0442u0430u043bu044cu043du043eu0439 dimension and determine the speed of relaxation of stresses.in the event of u0444u0440u0430u043au0442u0430u043bu044cu043du043eu0439 dimension from the standard values for the subject of the rocks are approaching the dangerous u0441u043eu0441u0442u043e u044fu043du0438u044f of rocks, the time before the likely point of attack or collapse.the technical result is achieved by improving the accuracy and reliability of determining the point of impact, or the collapse of the rocks, with over, over u0435u0440u044bu0432u043du043eu043c monitoring.
