Guide: Panzhihua New Baima Mining Co., Ltd. introduced 1 atlas AMP in october2011# 8226; Copco cdm75 electric rotary drill, which is not only atlas amp# 8226; The first rotary drill sold by Copco in Southwest China is atlas amp# 8226; Nanjing factory group of Copco rotary drilling rig Department

Panzhihua xinbaima Mining Co., Ltd. introduced one Atlas Copco cdm75 electric rotary drill in October, 2011, which is not only the first rotary drill sold by Atlas Copco in Southwest China, but also the fifth is the first application of cdm75 electric rotary drill assembled by Atlas Copco rotary drilling Department in Nanjing factory in iron ore

Baima iron mine, located in Baima Township, Miyi County, Panzhihua City, Sichuan Province, is one of the three major mines of Panzhihua Iron and steel group. Its iron ore has a larger measuring range, and its ore reserves are 6billion tons. It is preliminarily estimated that it can be mined for 100 years. The mine is composed of tianjiacun, jiheping, xiajiaping, mabeilang and QINGGANGPING ore blocks. At present, the annual processing capacity is 15.5 million tons of raw ore and the annual concentrate output is more than 5.1 million tons. In 2012, the total annual stripping volume is planned to be 37.5 million tons

with the progress of the times and the development of the enterprise, Panzhihua xinbaima Mining Co., Ltd. (a subsidiary of Panzhihua Iron and Steel Group Mining Company) has successively introduced a number of blast hole drills, including Atlas Copco cdm75 electric rotary drill introduced in October, 2011, which is not only the first rotary drill sold by Atlas Copco in the southwest region, It is also the first application of cdm75 electric rotary drilling rig assembled by Atlas Copco rotary drilling rig department in Nanjing factory in iron mine

the mine is rich in reserves and difficult to exploit.

Baima iron mine is a large-scale vanadium titanium magnetite deposit, of which the ore reserves in tianjiacun and Heping are 1.1 billion tons. In terms of mining conditions, the highest exposed elevation of the jiheping orebody is 2267m, and the lowest erosion datum elevation of the mining area is 1423.8m. The mining area is characterized by large elevation, steep hillside, and stable ore and surrounding rock. Therefore, in order to save energy to the greatest extent and improve economic benefits, the Mine adopted the adit pass standard gauge railway development and transportation scheme

when talking about the original intention of choosing Atlas Copco cdm75 electric rotary drill, huangancheng, director of the mining workshop of Panzhihua xinbaima Mining Co., Ltd., said: "this drill has the advantages of simple operation, high reliability, strong mobility and high drilling efficiency, and fully meets our production requirements."

high drilling efficiency and long service life of drilling tools

it is understood that Baima iron mine and Heping mining area have adopted the rectangular hole layout method, and the hole spacing and row spacing are 6 × 9m, step height 15m, hole diameter 250mm, drilling depth 17 5m。 The Atlas Copco cdm75 electric rotary drill currently used in the mine has an input voltage of 6000V, a frequency of 50Hz, a transmission line height of M, and a compressor displacement of 53m3/min@7.6bar The wet dust removal method is adopted to meet the needs of mining in the rainy season. The dust removal effect is good and can effectively reduce pollution

Huang Ancheng was also very satisfied with the use of this rig. He said: "The motor of this drilling rig has been running for 1667 hours. In fact, the LFI components are characterized by high temperature stability and excellent impact strength. The drilling time is 1035 hours, the total drilling depth is 19944m, and the comprehensive perforation efficiency is about 20m/h, which is more than 30% higher than the average comprehensive perforation efficiency of some domestic drilling rigs of 15m/h.

Atlas Copco is also outstanding in the durability of drilling tools. According to Huang Ancheng, CD M75 electric rotary drill is equipped with original Atlas Copco drill pipe and stabilizer, which have been used for more than 20000m and 9000 m respectively, and are still in use; The average service life of some domestic drill pipes and stabilizers is less than 8000m and 5000m respectively. It can be seen that Atlas Copco's original drill pipe and stabilizer have obvious service life advantages, which can greatly help customers save costs and improve economic benefits

organize staff training to improve production efficiency

at present, there are more than 400 workers in Baima iron mine and Heping mining area, of which the cdm75 electric rotary drill fleet works two shifts a day, with two people in each shift. Since the introduction of this cdm75 electric rotary drill last year, the mine has a total of 10 people. However, due to the addition of flame retardant, it is unable to manufacture recycled fiber and has received professional training from Atlas Copco, which has effectively improved its own operation level and production efficiency. This not only reflects the importance Baima iron mine attaches to staff training, but also reflects Atlas Copco's brand commitment to providing customers with sustainable productivity. When talking about the future development, Huang Ancheng said: "in recent years, with the strong support of Atlas Copco, Baima iron mine has made significant improvements in economic benefits, production costs and safety assurance. I hope Atlas Copco can provide us with more and more excellent products and services in the future, and escort us to achieve the goal of 55million tons of annual stripping in 2015!"
