MULTIFUNCTION CONTROL GEODYNAMIC AND GAS-DYNAMIC STATE OF ROCK MASS. EVALUATION AND FORECAST THE STATE OF THE ROCK MASS
This article describes the multi-function control system of geodynamic and gas-dynamic state of a rock mass. Considered in more detail its structure, construction and application. The minimum system components, including seismic and acoustic monitoring and forecasting the state of the rock mass. Presents technical means complex multifunctional monitoring system, the principle of its construction, composition. Describes the principles of arrangement of seismic and acoustic sensors probes. The presented scheme of arrangement. The technical characteristics technical means. Consecrated evaluate and forecast the state of the rock mass. Basic characteristics of the multifunction system control geodynamic and gas-dynamic state of a rock mass. Lists the analyzed data (information packages about seismic, acoustic emission, identified seismic and seismic events, the intensity of seismic and acoustic emissions, the ratio of the amplitudes of high-frequency and low-frequency component of the spectrum of the acoustic signal, etc. on the basis of which analyzes and predicts the state of the coal seam surrounding rocks and rock masses in General. Methods of identifying regular components of the time series data. Describes methods for smoothing data, including the method of moving average, median smoothing method, method of least squares, method of negative exponentially weighted smoothing method bicubic splinesf.
