煤层瓦斯压力是决定煤层瓦斯赋存和动态性质的重要参数之一。在生产实际中,它是标志煤层瓦斯危险程度的一个重要指标。因此,测定瓦斯压力的准确程度,将直接影响到对瓦斯危害估计的正确性和所采用的防治措施的可靠性。最近有些同志询问,在测定煤层原始瓦斯压力时,测压钻孔内有涌水,这对测得的压力结果会产生怎样的影响。现就此问题谈 Gas pressure in coal seam is one of the important parameters that determine gas occurrence and dynamic properties of coal seam. In production practice, it is an important indicator of the degree of danger of coal seam gas. Therefore, to determine the accuracy of gas pressure will directly affect the accuracy of gas hazards estimates and the reliability of the control measures adopted. Recently, some comrades inquired that when measuring the original gas pressure in the coal seam, there was gushing water in the piezometric borehole, which would have an impact on the measured pressure result. Now talk about this issue
