Since March this year, the Iron and Steel Institute, the Fourth Hospital and the Professional Institute have carried out field tests on the No. 13 composite lining as planned with the strong support of three teams. The test section from DK2001 +100 ~ 200, a total of 100 meters. The first and second test sections of 35 meters long by the Iron Works, the four homes shared, the main test in the Ⅲ type of rock in the concrete lining of different thickness contrast test. The third test section, paragraph 30 meters long, borne by the professional academy, in the Ⅲ type of rock in the low-stress anchor instead of ordinary mortar bolt and the middle waterproof layer instead of spraying emulsified asphalt. The three experimental sections are currently supporting three initial volumes
