METHODOLOGY FOR RAPID DETECTION OF ABNORMAL GAS SITUATIONS AT THE EXCAVATION SITES OF MINES

The article is directed to the development of one of the approaches to decision-making by the personnel on the meaningful analysis and interpretation of emergency situations in mine workings. The technique of quantitative estimation of non- stationary processes for detection of abnormal gas situatio...

description	The article is directed to the development of one of the approaches to decision-making by the personnel on the meaningful analysis and interpretation of emergency situations in mine workings. The technique of quantitative estimation of non- stationary processes for detection of abnormal gas situations and emergency gassing has been offered. It has been focused on the full use of information redundancy, contained in the experimental implementations of the results of the interaction of technologies with the bottomhole part of the mountain massif. The following provisions were applied: the appearance of abnormal gas situations leads to a rupture of the interaction of gas dynamic processes at the sites of recording methanegrams, and the presence of a link indicates a «regular» development of situations. It has been shown, that, on the whole, the methodology is implemented in two stages: the evaluation of the significance of the connection by verifying the significance of the Spearman rank correlation coefficient when it is approximated by Student’s distribution and checking the stationarity of the observed connection at two time intervals of observation. It has been established, that the proposed technique, with appropriate modification, is also applicable to identification of soullars in mine workings. Two methods for monitoring gas evolution have been proposed. Verification of their content has been confirmed by mine experiments.
