Drill and Blast Optimisation at an Underground Copper-Gold

Abstract. The process of utilising drill and blast techniques is used to improve mining performance. Drill and blast techniques have been proven to be more efficient and cost-effective compared to conventional mechanical rock breakage with machines. The degree of efficiency of the drill and blast process varies from mine to mine.Drilling is the rst stage of open pit mining that has a considerable e ect on the other stages of mining, including blast- ing, loading, hauling and crushing.(PDF) SELECTION OF THE MOST PROPER DRILLING AND BLASTING

(PDF) Method for calculation of drilling-and-blasting

Purpose. Development of a new method for calculation of drilling-and-blasting operations parameters during underground mining with application of emulsion explosives taking into account theirLike many catchy mining phrases, “Drill to Mill,” “Pit to Plant,” “Mine to Mill” and “Mine to Market” are deceptively simple descriptions for complex, multi-layered processes. In the mining cycle, drill and blast (D&B) is arguably the first and most important step to get right. D&B operations impact the entire mining process, from mining An integrated approach to the drill and blast process

Vermeer Surface Miners: A better solution to drill and blast

Some challenges of drill and blast processes are also listed below. By managing these challenges, total cost of ownership can be minimised and overall mining processes should become more effective.Open-pit mining technology. Open-pit mining clearly offers a number of economic advantages over underground mining, especially now that mineral-processing technology has advanced to the stage where very low-grade ores can be treated profitably. 100 to 150 years ago, this was not the case, and mining was still much more selective.Open-Pit Mining Method and Process Epiroc

Blastability and Ore Grade Assessment from Drill Monitoring

Blasting performance is influenced by mechanical and structural properties of the rock, on one side, and blast design parameters on the other. This paper describes a new methodology to assess rock mass quality from drill-monitoring data to guide blasting in open pit operations. Principal component analysis has been used to combine The basic objective of this report is to highlight the principles and practices adopted in rock blasting operations for mining sectors. The aspects concentrated in this report are: a) Purpose and(PDF) ROCK BLASTING FOR MINING ResearchGate
