Hunan Yao Gang cemented tungsten mine torch bolting team, in September last year, No. 501 in the middle of the pulse of mechanized operation of No. 501 roadway heading, the creation of a single-headed month footage of 330.2 meters, 0.88 surface efficiency (m / working class), the average blasting efficiency 88%, average monthly footage of 20.7 meters into the excellent results. The operating lane lane section size of 2.4 × 2.4 m ~ 2, rock hardness f = 14 ~ 16, complex geological conditions. Yao Gang cents mine to take to strengthen the leadership and organization of laneway team,
