    • Methods for rapidly determining earthquake parameters of an earthquake include inputting a seismogram of the earthquake, searching concurrently in pre-established historical seismogram database and theoretical seismogram database by use of an approximate nearest neighbor search method, to find a set of seismograms similar to the input seismogram according to a preset similarity condition, and determining from the set of similar seismograms one or more seismograms matched with the input seismogram, and determining the earthquake parameters from the matched seismograms. With the present invention, it is possible to search in millions of seismograms and determine parameters for an earthquake in a few second, and thus realize rapid and even real-time estimation of earthquake parameters.
    • 用于快速确定地震地震参数的方法包括:输入地震图,并使用近似最近邻搜索法在预先建立的历史地震图数据库和理论地震图数据库中同时进行搜索,找到与输入相似的地震图集 根据预设的相似性条件确定地震图,并从相似的地震图集中确定与输入的地震图匹配的一个或多个地震图,以及从匹配的地震图确定地震参数。 利用本发明,可以在几秒钟内搜索数百万次地震图并确定地震的参数,从而实现对地震参数的快速甚至实时估计。

    • A system and method for testing gas migration process in the coal and rock mass are disclosed. The method includes the following steps: selecting a cylindrical coal sample, applying an axial pressure and a radial pressure to the coal sample under a sealing state, and/or increasing temperature, to desorb gas absorbed by the coal sample; guiding the gas desorbed from the coal sample by a guiding passage, detecting gas flow rate and pressure, analyzing gas composition and content, and achieving a data statistics. The method provides a theory and data basis for researching the forming and occurring process of gas outburst accident in coal mine. The system is simple and easy to use, and is suitable for migration research of the gas absorbed in the deep coal-rock mass.
    • 公开了一种用于测试煤和岩体中气体迁移过程的系统和方法。 该方法包括以下步骤:选择圆柱形煤样,在密封状态和/或升高温度下向煤样施加轴向压力和径向压力,以解吸煤样吸收的气体; 通过引导通道引导从煤样中解吸的气体,检测气体流量和压力,分析气体组成和含量,并实现数据统计。 该方法为煤矿瓦斯突出事故形成和发生过程的研究提供了理论和数据依据。 该系统简单易用,适用于深层煤岩吸收气体的迁移研究。
