Blasting Fragmentation Study Using 3D Image Analysis of a Hard Rock Mine
The blasting of rocks using explosives is performed to fragment rocky material into blocks and particles of different sizes. In addition, the sizes of fragments must be smaller than those of the feeding of primary crushing [1,2].Therefore, the optimization of drilling and blasting is essential for controlling ore fragmentation and, consequently, the MINES 3.1 Drilling. 3.2 Blasting 3.3 Recent Advancement in Drilling and Blasting Techniques 9-22 23-29 30-40 CHAPTER 4: REVIEW OF OPTIMIZATION TECHNIQUES 4.1 General 4.2 Optimization of Mine Production System through Operation Research Techniques 41-45 45-48 CHAPTER 5: DEVELOPMENT OF BLAST Optimization of Blasting Parameters in opencast Mines

Driving an Underground Mine Adit: Methods & Equipment
Where the rock is hard, 3-, 3½-, or 4-inch Leyner-type drifters are customary. In the softer ground, mounted jackhammer-type drills of about 2 5/8-inch bore may be used. Quite recently automatic-feed drifters have been introduced and are finding favor on some jobs. Wet-drilling is or should be used in all adit work.Furthermore, rock fragmentation affects the cost of drilling and blasting as well as the efficiency of subsequent operations such as loading, transportation, and secondary crushing [2,3,4,5]. The key objectives of mining blasting are to achieve the best rock fragmentation particle size distribution and obtain the optimum blasting parameters.Rock Fragmentation Size Distribution Prediction and Blasting

A Review of Artificial Intelligence Applications in Mining and
2.4 Drilling-Blasting. Drilling-blasting is an essential operation for rock fragmentation or rock movement in mining, especially in open-pit mines [60, 61]. According to scientists, the effectiveness of rock fragmentation is high, depending on the drilling and blasting parameters [62, 63]. Low effectiveness of rock fragmentation can causeIn blasting operations, a huge amount of energy is normally wasted to generate some unwanted issues in the surrounding zones, e.g., flyrock and oversize boulders. In this study, to solve these environmental issues of blasting, two phases of prediction and optimization were considered and applied. In the phase of prediction, the Prediction and optimization of flyrock and oversize boulder

Drivage Excavation Using Drilling and Blasting SpringerLink
The excavation is dominantly performed using drilling and blasting. The burn-cut blasting pattern is used in all the Indian metalliferous mines to make drivages. The pattern consists of a set of holes to be blasted against the free face provided by relief/reamer holes. The design parameters in burn-cut face blasting include drilling patternCurrent control of blasting and drilling in open-pit mines should be based on a two- stage process: first, technical calculations are performed on the parameters of the massive explosion based on available data on rockbed properties and structure. where special charging machines are used which form charges of variable density.
