Problems Faced By Dragline Machines Used In Mines
Evolution of Mining Equipment in the ...
· The draglines would dig out the face of the oil sands mine and place the piles of ore in a row along the side of the mine, where it would be later scooped up by the bucketwheel. The boom length on a typical oil sands dragline was 110 meters tall. These megamachines were electrically operated and could excavate up to 6,000 tonnes of oil sands per hour, travelling up to 3 meters per minute ...

Investigation of Cycle Time Segments of Dragline Operation ...
· Dragline is highly capital intensive equipment to procure, operate and maintain in any surface mining operation. Given this, every second of operation of this capital intensive equipment is absolutely important. Improvement of even a single second in the total cycle time has a tremendous bearing on the overall performance of this equipment. In this light, the present paper is an endeavour .

Optimization of transport passage with dragline system in ...
· Large dragline system can extract, transport and dump by one machine. This system is characterized as fewer equipments, higher operating efficiency, lower production costs, bigger capacity and higher reliability. When the dragline system is adopted, we can use casting blast which can throw more than 30% of the overburden directly into the minedout area, so it improves the stripping efficiency
(PDF) Improving Productivity of Dragline through ...
This study has used last 12year operational data of a dragline deployed in a large opencast coal mine. Collected data have been grouped into four maintenance strategies.

Dragline Automation— A Decade of Development
Mines have used several methods to achieve the necessary increase in overburden stripping productivity. First, draglines are routinely overloaded, exploiting the generous design safety margins by using larger buckets. Careful economic analysis has determined the optimal operating load that trades off productivity against machine damage. Networks of sensors monitor stresses on the machine and ...
CHAPTER 11 Mining Technology
capacity of a dragline, the machine used to remove the overburden in strip mining, varies in size from 10 to over 200 cubic yards. Many Eastern mines use stripping shovels instead of draglines; and stripping shovels currently are being used successfully at several strip mines in the West such as the Rosebud Mine in the Montana portion of the ...

Mining is bad for health: a voyage of discovery | SpringerLink
09/07/2019 · Mining continues to be a dangerous activity, whether largescale industrial mining or smallscale artisanal mining. Not only are there accidents, but exposure to dust and toxins, along with stress from the working environment or managerial pressures, give rise to a range of diseases that affect miners. I look at mining and health from various personal perspectives: that of the ordinary man ...

Seven ways new technology will impact the mining sector ...
04/07/2019 · Disruptive technology has been changing the face of mining, with labour and other impacts, since mining began. But the coming wave is different in quality and speed than anything we have seen before. 2) Technology is not a homogeneous force. Some new technologies—like automation and drones—will replace labour.
