| 摘 要： | 介绍了测定煤样中初始释放瓦斯膨胀能的原理和测定方法，设计了一套初始释放瓦斯膨胀能的测定装置。通过对突出与非突出煤样的测定表明，煤样中初始释放出来的瓦斯膨胀能要比后期涌出的瓦期膨胀能大得多，并且随着煤样初始释放瓦斯膨胀能的增大，揭煤时的动力现象也增大。

| Abstract: | The principle and method to measure the initial releasing expanding energy of gas from coal are introduced, and a set of measuring instrument is also built up. According to some test results of outburst and non outburst coal, the first releasing gas expanding energy from coal is much larger than the later one, and its quantity increases with the intensity of outburst in the uncovering coal seam. |

| Keywords: | the initial releasing methane expanding energy coal and gas outburst outburst prediction |
