Equipment Type: EBZ200H Time of use: January 9, 2009 - June 6, 2009 Place of use: Yungang Town, Datong City, Shanxi Province Unit: Qingci Kiln Mine of Tongmei Group Roadway and its geological conditions 1, the total length of the roadway is 2000 meters. 2. The hardness of the roadway part of the rock is F8-F9, semi-coal rock, and the cross-sectional shape is rectangular. Roadway support section and form section: 4.2 meters×2.6 meters Support: anchor cable net footage cumulative footage about: 1400 meters; Average footage: 11 m/day; *8981 large footage: 15 meters/day. Customer evaluation: Sany EBZ200H hard rock boring machine in early January 2009, the whole machine performance is stable, the failure rate is less, in early May, successfully completed a 1300 meters of roadway excavation task, is now 2000 meters of roadway excavation. Due to the hardness of the roadway rock, our mine excavation team was only able to complete the task of 200 meters in the past. After using Sany's hard rock boring machine, the excavation team was able to successfully complete the task of 330 meters set by our mine, greatly improving the roadway excavation speed and directly improving the production efficiency of our mine.
