Method and system for continuously pumping gas in coal uncovering process of vertical shaft

The invention provides a method and system for continuously pumping gas in the coal uncovering process of a vertical shaft. The method comprises the following steps of: constructing a concealed gas pumping pipeline groove on a section which is a preset distance away from a shaft barrel of the vertical shaft by blasting; pre-burying a gas pumping pipeline in the concealed gas pumping pipeline groove; constructing a plurality of pumping drill holes on an uncovered coal seam outside a wild path at the bottom of the shaft barrel of the vertical shaft; and pumping gas from the uncovered coal seam by using a gas pumping hose which is connected with the gas pumping pipeline and is arranged in the plurality of pumping drill holes. By adopting the method and system for continuously pumping gas in the coal uncovering process of the vertical shaft, provided by the embodiment of the invention, the technical defect of unavailable continuous pumping of coal seam gas due to frequent damage of blasting ...
