Abstract

Изобретение относится к геофизическим исследованиям горных пород, в частности к способам контроля и определения опасного состояния массива горных пород при подземных горных работах, при котором возбуждают акустическую эмиссию техногенным источником, регистрируют сигналы акустической эмиссии, обрабатывают полученные данные, по результатам обработки судят об опасном состоянии массива горных пород, и может быть использовано в горнодобывающей промышленности, прокладке тоннелей и других подземных работах. Согласно изобретению в качестве техногенного источника используют горную машину, производящую выработку. Дополнительно регистрируют сигналы акустической эмиссии от естественных источников массива горных пород. Обработка полученных данных производится с использованием изменения фрактальной размерности временного ряда акустической эмиссии, в котором определяют показатель фрактальной размерности и определяют скорость релаксации напряжений. При отклонении показателя фрактальной размерности от его стандартного значения для обследуемого массива горных пород судят о приближении момента опасного состояния массива горных пород, оценивают время до вероятного момента горного удара или обрушения. Достигаемый технический результат - повышение точности и достоверности определения момента возможного горного удара или обрушения массива горных пород при непрерывном мониторинге.The invention relates to geophysical studies of rocks, in particular to methods of monitoring and determining the dangerous state of an array of rocks during underground mining, in which excite acoustic emission by man-made source, record acoustic emission signals, process the data, the results of processing judge the dangerous state of the array rocks, and can be used in the mining industry, laying of tunnels and other underground works. According to the invention, a mining machine is used as a man-made source. Additionally, acoustic emission signals from natural sources of the rock mass are recorded. Processing of the obtained data is performed using the change in the fractal dimension of the time series of acoustic emission, in which the index of the fractal dimension is determined and the stress relaxation rate is determined. When the indicator of fractal dimension deviates from its standard value for the examined rock massif, an approximate moment of the dangerous state of the rock mass is judged; the time to the probable moment of a rock blow or collapse is estimated. Achievable technical result - improving the accuracy and reliability of determining the moment of possible rock bursts or collapse of the rock mass during continuous monitoring.
