通过断裂力学方法研究西华山内接触带矿脉群构造的成因。根据详细实测资料发现矿脉群具有较高的断裂密度和断裂应变，对比矿脉群扩展的临界条件，说明矿脉群发展过程中驱动应力为上升的趋势，其原因是岩体界面的止裂作用使矿脉扩展阻力增大，导致矿脉扩展力相应增高，以维持矿脉扩展，形成了产生西华山大型脉状矿床的力学条件，不同于均匀体中形成的细脉带类型。
Study on the genesis of the contact belt faulting in Xihuashan Mountain by means of fracture mechanics. According to the detailed measured data, it is found that the mineral assemblages have higher fracture density and fracture strain. Comparing with the critical conditions for the extension of the group of mines, it indicates that the driving stress is increasing during the development of the group of mines. Expansion resistance increases, leading to a corresponding increase in the expansive force of the vein to maintain the extension of the vein, forming a mechanical condition for generating large vein-shaped deposits in the Xihuashan Mountain, which is different from the type of the veinlets formed in a homogeneous body.
