The Study on Gas Drainage of Mining Perturbation Pressure Relief
In this paper the change of floor pressure was analyzed under mining perturbation. On this base analyzed the regulation of gas emission in this case. Drew a conclusion that the gas of adjacent coal bed entered goaf plentifully from the floor crack, and a lot of entered air of working face. These lead to overrun of gas in return-air and gas drainage tunnel. Found out the crack-belt of gas used mining perturbation influence. It not only is the gas storage place but also a good flowing tube. Used this method into engineering practice, based on different source of gas when mined liberated seam adopted horizontal drilling in roof and floor and high-order position gas drainage tunnel method and so on, realized high strength solid gas drainage, obtained a good effect.
