In domestic metal mines， the drilling and blasting method is used for deep mining， and it has a long construction period with high risks. The TBM method has been widely used in water conservancy， municipal engineering and highway construction because of its fast construction speed， safety and good quality. With the continuous application of “four new technologies”， the continuous improvement of equipment， and the continuous improvement of domestic TBM performance and quality， construction costs are significantly reduced. However， the TBM method has not been applied to develop deep mining roadways. The main reasons are： the deep geological conditions of the mine are complex； the roadway cross-sections change， and the adaptability of TBM is poor. This paper analyzes the possible risks of water inrush， rock burst， high ground temperature and so on when the TBM method is used in deep roadway development in metal mines， and expounds the solutions for these risks. It is concluded that these risks can be eliminated with the solutions， and TBM can be applied in deep roadway boring in metal mines.
