Sandvik DD2710 assisted flood rescue
Tungsten is a very important resource, which is widely used in many fields, such as space, atomic energy, ship, automobile industry, and so on. China's tungsten reserves account for 40% of the world, ranking first in the world, and production, consumption and export are also the first in the world.
Wenshan, which is located on the Sino Vietnamese border, has gone through the transition from war to peace. Now it has no smoke, but the roadside marks the road signs of the "landmine area" and "non open area". It can still let people see traces of the war years. With the development of economy, Wenshan has also got its proper development. With its unique natural beauty, it is called the "fairyland Jedi" natural scenery, attracting a large number of tourists to visit. Besides, mineral resources are also the advantages of Wenshan.
Wenshan Zijin Malipo Tungsten Industry Group Co., Ltd. is located in Malipo County of Yunnan Prefecture of Wenshan Province, is a development oriented enterprise group and the development of tungsten ore, tungsten ore associated mineral resources in large mining. As the main mine of the group, the South Wenhe tungsten mine has been developing into a large scientific, benefit and environmental friendly enterprise in Yunnan province. In response to the national advocacy of green mines, intelligent mines, and the management concept of the harmonious mining area.
Since the founding of the 2007, a lot of changes have taken place in the South Wenhe tungsten mine. Before the mine has been using traditional hand held drilling for artificial drilling, this drilling way is relatively backward, and the working principle is that the equipment connects the air compressor and the air pipe, so that we can use high pressure air to drill, at the same time, we need to manually stand on the side to carry on the handheld. The 4.1X4.6 specification of a class needs 5 such drilling machine continues to run 6 hours per month, but the maximum 40 meters.
The second foot rock tailings drainage tunnel inlet engineering, is Nanwenhe tungsten rock tailings drainage project to enhance foot ability, eliminate hidden dangers of tailing pond safety of the tunnel, a total length of 321.84 meters, excavated section is 4.1X4.6 square meters, according to the requirements of the group to be through in the flood season this year, increasing the safe passage for the Nanwenhe tungsten mine safety the flood season. This project successfully completed, thanks to the help of Sandvik DD2710 and modern management, the highest monthly engineering excavation footage of 249 meters, the highest single day footage of 9.8 meters record.
"We are close to DD2710 Sandvik jumbos, the use of a year, the safety performance of the car is very perfect. In the process of use, the efficiency of the trolley has a great advantage in terms of efficiency. The average perforation is 3 meters, and the hole depth is between 1 and a half to 2 and a half, which greatly reduces the intensity of laborers. The advantage is very obvious instead of the traditional handheld drill. It also conforms to the national standard of capacity, and also meets the requirements of national safety, environmental protection, laws and regulations. Xiao Yunbin, the captain of the mechanized mining team of the South Wenhe tungsten mine of Zijin mining, said.
The model provides a large square cover area, can rotate 360 degrees and automatically flat, the section is fast and accurate. Equipped with a Sandvik HLX5 rock drill, the impact power of the drill can reach 20 kW. It has a high level of drilling system, with the industry's leading drilling performance, good drilling tool life, and excellent equipment stability. In addition, the design of the whole drilling machine ensures a good view and body stability. The four wheel drive articulated chassis has strong power and can run safely and safely in narrow lane.
After that, due to the attention of mine to mechanization and the application of information technology and equipment, a Taishan trolley single arm rock drilling platform DD2710 was introduced. The equipment is designed for the mine roadway driving, covering a section of 34 square meters. It can work and turn in a roadway with a width of only 2.7 meters. The main components of the drilling equipment and other underground part is general Sandvik drill, which ensure high level drilling performance, production capacity and interchangeability.
Since entering the Nanwenhe tungsten DD2710, Sandvik sent Service Engineer 24 hours in mine to follow up the project, to ensure the smooth progress of the project.
Wonderful recommendation:
Macro economy under the control of central policy
Scientific and technological innovation and the mechanized development of Agriculture
