METHOD OF FORECASTING OF HAZARD OF GAS-DYNAMIC PHENOMENA IN ROCK MASS AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2010 - IPC E21F5/00 E21B47/10 G01F1/76 

Abstract RU 2382202 C1

FIELD: mining.

SUBSTANCE: invention refers to mining industry and may be used for forecasting of hazard of gas-dynamic phenomena during mining on outburst and high-gas-containing strata. Method of forecasting of hazard of gas-dynamic phenomena in rock mass includes drilling of each exploratory hole with preliminary sealing of their mouth. Measurement of quantity of gas and dust coal is performed with sealing of measuring channels continuously and simultaneously with holes drilling upon leaving of drilling flight in hole. Hole depth is estimated by continuous measurement of its current depth, average values and mean-square deviations of quantity of gas and dust coal are determined on profiles of gas and dust coal quantity depending on hole depth, and availability of zones of increased strata pressure is determined on segments of hole depth where specific quantity of dust coal is higher than average values per value of mean-square deviation, and availability of zones of increased presence of gas is determined on segments of hole depth where specific quantity of gas is higher than average values per value of mean-square deviation, average presence of gas of dust coal in place of exploratory hole driving is determined by integration of gas quantity profile depending on hole depth and, if value of average presence of gas exceeds value of threshold presence of gas, determination is performed by provided formula and upon coincidence of zones of increased strata pressure and increased presence of gas, availability of zones hazardous due to gas-dynamic phenomena is determined, in them sorption capacity of dust coal is determined by means of interruption of drilling and determination of current quantity of evolved gas in time by approximation of gas evolution kinetics by function and at values of time constant less than 250 sec these zones are considered extra hazardous. Device for implementation of specified method is presented.

EFFECT: improvement of accuracy and validity of determination of zones hazardous as per kinds of gas-dynamic phenomena.
