摘　　要：结合潞安矿区近年煤层瓦斯压力的测定工作,分析了影响煤层瓦斯压力测定结果的因素,得出提高瓦斯压力测定成功率的方法:充分考虑煤层地质条件对测压的影响,加强对特殊地质构造的监测,并在测压时避开;通过分析认为潞安矿区的煤巷原始应力区为巷道宽度的3-5倍。对钻孔参数进行优化并选择合适的封孔工艺,同时使终孔位置避开巷道采动影响区。Based on the measurements of gas pressures in Lu'an mining area in recent years,the influence factors of gas pressure measurement results are analyzed systematically,and the methods to improve measurement success rate is obtained as well. These methods are as following: taking a full consideration of the impact of seam geological conditions on measurement values,strengthening the monitoring of the special geological conditions and avoiding it in measurement work; optimizing the drilling parameters and select the appropriate sealing process; confirming the tunnel pressure released range by the measurement of drill cuttings and drilling bits.
