摘要
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。
In that the direct method of measuring coal seam gas pressure has been using generally at present in mine, it is necessary to summary and analyze its status to provide guidance for researching in depth. Summarized and analyzed its status from two aspects, sealing technology and influence laws about accuracy and speed of gas pressure measurement, discovering some problems. Based on research findings of coal seam gas flow theory, think that the numerical model to describe gas flow in coal seam during measurement does not adhere to the development trend of gas flow theory.
