由于目前煤矿多采用直接法测定煤层瓦斯压力,因此有必要对其研究现状进行总结和分析,为更深入地研究提供指导。从测压封孔技术研究和煤层瓦斯压力准确快速测定影响规律研究探讨了直接法测定煤层瓦斯研究现状,并指出了研究中还存在的问题。结合煤层瓦斯流动理论研究成果,认为描述测压过程中瓦斯流动的数学模型没有紧随煤层瓦斯流动理论的发展趋势。
Because of the fact that many coal mines use the direct method to determine the gas pressure in the coal seam, it is necessary to summarize and analyze the current situation of the research and provide guidance for further research. This paper studies the research on the influence law of pressure measurement and sealing technology and the accurate and rapid determination of gas pressure in coal seam. The status quo of coal gas research by direct method is discussed. Some existing problems are also pointed out. Combining with the research results of gas flow theory in coal seam, it is considered that the mathematical model describing the gas flow in the process of pressure measurement does not follow the trend of coal gas flow theory.
