Abstract: Based on the characteristics of high ground stress, high ground temperature and high seepage pressure in deep coal seam, the problems were analyzed for the pressure measurement in the deep area. Some measures were applied in the pressure measurement, including controlling the gas chamber volume of pressure-testing, the compound method of pressure consolidation with casing pipe and multistep sectional sealing, the gas pressure measurement with active air supply, then the feasibility test was conducted in Pansan Coal Mine. The results showed that the compound technology of pressure consolidation with casing pipe and multistep sectional sealing could effectively seal the deep surrounding rock fissure, and eliminated effect of water pressure and deep coal seams. The measurement time was greatly shortened by the gas pressure measurement with active air supply in deep and high gas pressure area, and its error was very small. Based on measures above, gas pressure of uncovering coal area in No.7 and No.8 coal seam was rapidly and accurately determined. They respectively had values of 2.9 MPa and 3.14 MPa.
