  • Patent number: 10794174
    Abstract: A dynamically self-balancing pressurized borehole sealing apparatus and method thereof for coal seam gas pressure measurement having a pressure measuring tube arranged in a borehole with one end of the pressure measuring tube provided with a pressure measuring unit. The pressure measuring tube is wrapped with an expansion airbag and provided with a pressure introducing hole communicating with the expansion airbag. On each side of the expansion airbag, the pressure measuring tube is wrapped with a front borehole inflatable sealing airbag and a rear borehole inflatable sealing airbag respectively. A gel injection chamber is reserved between the front borehole sealing airbag and the rear borehole sealing airbag and between the expansion airbag and an inner side of the borehole. Gas from the pressure measuring tube expands the expansion airbag and squeezes sealing gel in the gel injection chamber into borehole fractures for dynamic pressurized sealing.
