Gas Unusual Gush Region Prediction Based on Geological Dynamic Division
For the the mine deepth and intensity enhancing, gas unusual gush happens in part of the low gassy coal mine. There are two reason for the gas unusual gush, one is geologic factor, the other is excavate factor. The geologic structure is affirmatory, therefore we can recognize and predominate it by the fact that analysing and detecting and so on. This paper apply plate tectonics theory and region structure evolution theory, analyse coal structure, consult anciently gas gush data, study gas gush orderliness, and then, studied deep of the low gassy coal mine gas unusual gush. This paper divided I-V class movement fracture, synthesize analysed the class of fracture and stress, and ascertain its incidence, combining with geologic condition, divided 9 gas unusual regions. Research indicate, tructure of Yuan Baoshan pan is Xi-Type, region terrain of Hongmiao coal seaM show itself center high and around low. Nw orientation fault Analogical reasoning, protrude terrain is propitious to gas preserved and concave terrain cumber gas preserved. Mine geologic structure is not good for gas preservation, this is the reason why gas is low in Hongmiao seam.
