Abstract
Sposób wykrywania i minimalizacji zagrożenia metanowego w rejonie ściany wydobywczej polega na tym, że na wybiegu ściany wydobywczej dokonuje się okresowo lokalizacji rejonów, w których występują koncentracje naprężeń (N) metodą pasywnej tomografii prędkościowej z wykorzystaniem sejsmometrów (8) i niskoczęstotliwościowych geofonów (9). Jednocześnie dane te porównuje się z bieżącymi pomiarami sejsmoakustycznymi lokalizującymi miejsca (M) zgrupowania trzasków towarzyszących pękaniu górotworu na wybiegu wyrobiska ścianowego, z pomiarami zawartości metanu i pomiarami przepływu powietrza w tym wyrobisku. Przy czym, miejsca koncentracji naprężeń (N) przed frontem ściany wydobywczej lokalizuje się poprzez wykonywanie aktywnej tomografii osłabieniowo - tłumieniowej z uwzględnieniem pozycji usytuowania kombajnu ścianowego (13) w wyrobisku ścianowym (B), następnie dokonuje się korelacji wyżej wymienionych parametrów w aspekcie czasowym i przestrzennym, a po stwierdzeniu, że współczynnik korelacji przekracza założoną wartości krytyczną realizuje się procedury profilaktyczne minimalizujące zagrożenie metanowe. W układzie do układu analitycznego (5) podłączony jest sejsmiczny system rejestrujący (1), system metanometryczny (3), układ wykonawczy (6) oraz panel sygnałów ostrzegawczych (7). Przy czym, do sejsmicznego systemu rejestrującego (1) z co najmniej czterema sejsmometrami (8), z co najmniej czterema niskoczęstotliwościowymi geofonami (9) i z co najmniej dwoma czujnikami naprężeń (10) podłączony jest sejsmoakustyczny systemem rejestrujący (2) z co najmniej czterema geofonami (11) oraz układ kontroli położenia i pracy kombajnu ścianowego (4) z czujnikiem położenia kombajnu ścianowego (12).The method of detecting and minimizing methane hazard in the region of the mining wall consists in the fact that on the runway of the mining wall periodically locations of regions where stress concentrations occur (N) by means of passive speed tomography using seismometers (8) and low-frequency geophones (9). At the same time, these data are compared with current seismoacoustic measurements locating places (M) of the grouping of cracks accompanying the cracking of the rock mass on the runway of the longwall, with measurements of methane content and air flow measurements in this excavation. At the same time, the places of stress concentration (N) in front of the mining wall are located by performing active suppression tomography taking into account the position of the longwall shearer (13) in the longwall excavation (B), then the above-mentioned parameters are correlated in terms of time and space , and after finding that the correlation coefficient exceeds the assumed critical value, preventive procedures are minimized to minimize methane risk. In the system, the analytical system (5) is connected to a seismic recording system (1), a methane-metric system (3), an executive system (6) and a warning panel (7). At the same time, a seismic recording system (2) with at least four geophones is connected to a seismic recording system (1) with at least four seismometers (8), with at least four low-frequency geophones (9) and with at least two stress sensors (10). (11) and the system for controlling the position and operation of the longwall shearer (4) with the longwall shearer position sensor (12).
