这份报纸论述发生在一条 migmatite 隧道学习它的形成机制的水流入和泥爆炸的案例研究。地质的调查和矿物学的分析证明在 migmatite 的那水流入和泥爆炸是仔细与主人岩石的部件有关。高可溶的矿物质满足，例如，方解石和白云石，将使 migmatite 岩石容易被裂成碎片， isintegrated 并且最后形成不同种类连接或连接半的静脉。领域探索表明在 magmatite 隧道的大多数洞被地下水侵蚀并且形成了大互连的网络。在 magmatite 隧道的二个差错和堤成为了比较喜欢的路径并且为很多的降水和泥泥浆提供了大便利。由于高水位线压力和强风骚乱，洞能很快象各种静脉一样连接对方，形成为水流入和泥爆炸的一条复杂地面隧道。到水流入和泥的潜在的出现冲破了的估计，冲破系数的水被采用。结果证明冲破 magmatite 隧道的系数的水比阀值价值大得多，解释水的事故能被用来流入和泥爆炸发生在 magmatite 隧道。

英文摘要：

This paper presents a case study of water inrush and mud burst occurring in a migmatite tunnel to study its formation mechanisms. The geological investigation and mineralogical analysis showed that water inrush and mud burst in the migmatite was closely related to the component of the host rock. High content of soluble minerals,e.g.,calcite and dolomite,would make the migmatite rock prone to be fragmentized,isintegrated and eventually form different sorts of connected or semi-connected veins. The field exploration revealed most cavities in the magmatite tunnel were eroded by groundwater and formed large interconnected networks. The two faults and the dike in the magmatite tunnel became the preferred paths and provided great convenience for plenty of precipitation and mud slurry. Due to high water pressure and blast disturbance,the cavities can soon connect each other as well as all sorts of veins,forming a complex ground channel for water inrush and mud burst. To estimate the potential occurrenceof water inrush and mud burst,the water bursting coefficient was employed. The results showed the water bursting coefficient of the magmatite tunnel was much bigger than the threshold values and it can be used to explain the accident of water inrush and mud burst occurring in the magmatite tunnel.
