摘要
对煤层瓦斯钻孔周围应力分布规律进行分析,能够为确定合理的钻孔布置和瓦斯抽放参数提供依据。本文采用UDEC(通用的离散元程序)工程模拟软件对煤层钻孔应力场分布规律进行模拟分析,得出了煤层瓦斯钻孔周围最大、最小主应力的分布规律和变化规律,为煤矿瓦斯钻孔参数布置提供一定的理论依据。
Stress distribution law around coal seam gas drilling is analyzed to provide the basis to determine the reasonable drilling layout and gas drainage parameters. Using UDEC engineering simulation software to analyze coal seam drilling stress distribution law,obtains the maximum and minimum principal stress distribution and change law around coal seam gas drilling. It provides a certain theoretical basis for gas drilling parameter layout.
