Atlas? Kepuke open hole drill power construction in winter
In 2015, the iron and steel industry and mining industry continued to decline, and even faced a crisis of survival, although the construction machinery industry is slightly stronger than in comparison, but also struggling to survive in the predicament.
Facing the winter each enterprise does not sit still, as the saying goes, the plight of people to grow, the growth of enterprises is also. Wengfu group under the wengfuphosphatemine bold use of Atlas? FlexiROC D65 Copco DTH rig open, in the mining industry downturn, improve production efficiency, reduce operating costs, reduce the pressure to bring the industry to survive the difficulties.
Wengfu Phosphate Weng'an county is located in the territory of Guizhou province and Fuquan City, mining engineering is divided into two periods. In 2.4 kilometers long from north to south, east-west width of 1.6 kilometers, the total area of 3.4 square kilometers, ore reserves of 90 million tons, the total stripping volume of 240 million cubic meters, in 2015 the ore production was 3 million 500 thousand tons, the total stripping volume of 20 million 500 thousand cubic meters, is currently the nation's largest open-pit chemical mines.
In recent years, Li Fu phosphate mine has been working hard to promote the modernization of mine construction, and gradually from the "independent management" to "technology management" mine transition, perforation blasting as the first link of the entire mining process, it is particularly important. Mine production requirements the construction unit must finish the task on time, therefore, high requirements on the efficiency of drilling equipment, equipment can meet the demand of producing assault grab.
In this area there are 6 Atlas? FlexiROC D65 Copco DTH Drill open, 3 of which is purchased in 2015, the 6 equipments belong to different construction units, has made an important contribution to the safe and efficient production of coal mine.
In the process of using, users have expressed satisfaction with Atlas? FlexiROC D65 Copco DTH Drill open, flexible action, praised for its high efficiency, comfortable operation and low fuel consumption.
The rock hardness of the cave mine is F=8, and the top bench blasting method is used for mining. The step height is 12 meters, the depth is 1.5 meters, the hole depth is 13.5 meters, the hole diameter is 203 millimeters, the drilling angle is 90 degrees, and the hole net parameter is 6 x 7 meters. Manager Li FlexiROC D65 rig from the operation since June 1, 2015, has been completed with a total footage of 76 thousand meters, the total operating time of the engine for 2295 hours, the impact time is 1485 hours, the comprehensive efficiency and net efficiency of perforation perforation were 33 meters and 51 meters / hour / hour. And in the best condition, the rig has completed 80 holes drilling task within 24 hours, the highest comprehensive perforation efficiency of 45 meters / hour.
About the future, the end user said, the background in the mining market downturn, enterprises should be more cautious to invest, just like Atlas? This can really bring Copco reliable products and quality services for users of the enterprise, in order to become a trusted partner.
