| 摘 要： | 用数学模型的方法对大同侏罗纪煤田的１５个煤层进行频散和振幅分布模拟：夹矸大于０．２ｍ时，对频散和振幅分布有影响；对地质非对称模型，最大振幅偏离煤层中心。

| Abstract: | The mathematical model method is used to simulate the frequency dispersion and amplitude distribution for fifteen Jurassic coal seams in Datong coalfield.The partings with the thickness more than 0 2m have the influences on the frequency dispersion and amplitude distribution.In the asymmetric geological model,the biggest amplitude deviates from the centre of seam. |
