2505工作面在最大倾角达35°的情况下,采取“硬过”的方式顺利通过了实际落差10m的DF47断层。研究了在大倾角条件下工作面过实际落差10m大断层的关键技术,现场应用效果良好,经济和社会效益十分显著。 The 2505 working face passed the DF47 fault with a real drop of 10m in a “hard-over” way with a maximum inclination of 35 °. The key technology that the working face has fallen by 10 m in the case of large dip angle is studied. The field application is effective and the economic and social benefits are significant.
