Abstract
Disclosed is a method for measuring gas pressure of a close-distance seam group simultaneously, including the following steps: constructing a pressure-measuring drill hole inclined downwards; lowering a first seam piezometer tube, lowering a baffle and a polyurethane blocking material after a tube head reaching a lowermost seam; and installing a gas pressure gauge; lowering a second seam piezometer tube, lowering the baffle and the polyurethane blocking material after the tube head reaching a second layer of seam; and installing the gas pressure gauge; lowering a nseam piezometer tube, lowering the baffle and the polyurethane blocking material after the tube head reaching a nlayer of seam; and installing the gas pressure gauge; injecting a high-water and quick-solidifying material into the drill hole; and connecting the gas pressure gauges through optical fibers, and connecting the gas pressure gauges with a ground control system.
