摘要
为了在测压孔积水条件下准确测定煤层瓦斯压力,通过理论分析测压孔周围三维空间内瓦斯、水压力的曲线分布,得出测压孔内瓦斯压力恢复曲线为双曲线形,水压恢复曲线为直线形,在寺河矿三水沟对钻孔瓦斯压力恢复曲线的测定验证了上述结论。
In order to accurately measure the seam gas pressure under the condition of the pressure measured borehole with water, with the theoretical analysis on the gas and water pressure curve distributions in the 3D space around the pressure measured boreholes, the gas pressure recovery curve measured from the pressure measured borehole was double curves and the water pressure recovery curve was a straight line. The measurement of the gas pressure recovery curve measured form the borehole in Sanshuigou of Sihe Mine confirmed the above conclusion.
