The case of Shandong Luneng Yunnan Yundong Energy Branch

Equipment Type: EBZ200H Time of use: November 16, 2008 - June 2, 2009 Place of use: Wule Industrial Plaza, Huangnihe Town, Fuyuan County, Qujing City, Yunnan Province Unit of use: Shandong Luneng Yunnan Yundong Energy Branch Roadway and its geological conditions 1. The total length of the roadway is about 1700 meters. 2. The hardness of the roadway rock is above F6, and the local is F8, and the cross-sectional shape is arched. Roadway support section and form Section: 5.5 meters× 4.8 meters Support: anchor rod, anchor cable footage cumulative footage about: 850 meters; Average footage: 4.8m/day; *8981 large footage: 7.1 m/day. Customer evaluation: Sany EBZ200H hard rock boring machine has been running normally since November 2008, the hardness of the equipment tunneling roadway is F6-F8, the roadway geology is complex and changeable, and the support workload is relatively large, and it takes about 10 hours a day to support. In nearly 28 sections, the equipment can excavate about 130 meters per month under the condition that the support work is relatively severe, which proves the excellent quality of Sany equipment. In March 2009, the footage reached 148 meters, and the equipment broke the record of the whole rock roadheader in the large section of our mine.
