drilling efficiency. Efficiency is defined as a metric of productive output for a given a set of inputs. This paper discusses how drilling efficiency is measured, the difficulties and ambiguities associated with productivity measures, and the technologies that have improved drilling efficiency. The analysis focuses on the operational factors File Size: KB. Optimization of drilling and blasting operations in an open pit mine—the SOMAIR experience Article in Mining Science and Technology (China) 19(6) November with 1, Reads. Drilling and drilling technology play a major role in the Algerian mining industry. In fact, it would be fair to say that the optimization of drilling parameters is an integral part of the. Drilling for Mining Operations. Importance of Drilling and Sampling: • Important mineral exploration procedure • Delineate subsurface conditions • Expensive • Number of techniques Microsoft PowerPoint - (7) Drilling for mining operations Author: Administrator Created Date.

The components of a drill rig are (1) the rig itself, which supplies the power to mobilize, drill rock, and remove the drill cuttings from the hole; (2) the mounting; (3) the drill steels or drill string; and (4) the drill bit. There are two basic drilling methods—percussion and rotary—classified inFile Size: 1MB.

The drilling method and size of the drilling rig used depends on the type of rock and information sought. The most common drilling method is very similar to water bore drilling and is usually completed in a day. The degree of disturbance around the hole varies with each Size: KB. As part of this project, the mine commissioned two new exploration drill rigs from Atlas Copco – a Diamec U4 and the larger Diamec U6 – both of which have achieved productivity records. Drilling 15 hours per day in a 5 x 6 m diameter drift, the Diamec U4 achieved an average productivity rate of m per month, % better than previous.

Mining Engineering Analysis. This textbook sets the standard for university-level instruction of mining engineering principles. With a thoughtful balance of theory and application, it gives students a practical working knowledge of the various concepts presented.   An introductory text and reference on mining engineering highlighting the latest in mining technology Introductory Mining Engineering outlines the role of the mining engineer throughout the life of a mine, including prospecting for the deposit, determining the site's value, developing the mine, extracting the mineral values, and reclaiming the land afterward.5/5(2).

Washington, DC: The National Academies Press. doi: / The life cycle of mining begins with exploration, continues through production, and ends with closure and. However, there isn’t any study in literature about how to use this metric for mining equipments such as shovel, truck, drilling machine etc. This paper will discuss the application of OEE to measure effectiveness of mining equipment. It identifies causes of time losses for shovel and truck operations and introduces procedure to record time Size: KB.
