There are 2 inclined shafts and 1 exit guide. The ground spans Daotai Township of Longquan City and Anmin Township of Songyang County. The geological conditions along the railway are very complicated, with 12 faults and 9 joints belt. In addition, the surface water is relatively developed with a maximum water inflow of 79120 square every 24 hours and a maximum buried depth of around 800 meters. There are extreme conditions such as high and low temperature and high ground stress, so that the construction conditions are extremely difficult, and the safety risk is extremely high.
