摘要
依据关于突出机理的“球壳失稳”假说对突出孔洞及压出孔洞的形成过程进行了研究。通过突出模拟试验证实压出实际上是一种弱突出现象，论证了突出孔洞的形状与煤体的初始释放瓦斯膨胀能大小有关，并对突出孔洞及压出孔洞的形成机理进行了解释。
According to the principle of the 'spherical shell destabilization' theory, the forming processes of outburst hole and extruding hole are studied. Extruding is demostrated as a 'weak outburst phenomenon' by a lot of outburst simulation tests. It is proved that the shape of outburst holes is related to the expansion energy of initial released gas from coal. In the end, the forming mechanism of outburst hole and extruding hole is explained.
