Drill-and-blast tunnels may vary in length from 16.4 to 197 feet (5 to 60 m) and are used for underground utility, highway, railroad, mass transit tunnels, and underground mining. In smaller tunnels, drills are individually mounted on bars or columns with an adjustable clamp that permits.
Drilling and Blasting Process | Mining Information Systems and .Drilling and Blasting Process. Data into Action. Commercial off-the-shelf technology is used throughout mining, largely as machine operator aids. However, these systems, as well as health monitoring systems, often produce copious amounts of data that largely goes unused. The MISOM lab researches the technologies and.drill and blast process,Blasting, drilling procedures need to be done professionallyMar 21, 2017 . A common problem for engineers and consultants for aggregates mines is the critical challenge of achieving proper blasting. Many of the problems faced came from operational inefficiencies in the drilling and blasting program. Most mines believe that better blast design will help save costs, improve.John Frank

Blasting is an essential part of the mining cycle. In virtually all forms of mining, rock is broken by drilling and blasting the rock. Blasting technology is the process of fracturing material by the use of a calculated amount of explosive so that a predetermined volume of material is broken. From the earliest days of blasting with.
Abstract: High-performance drill and blast methods for tunnel construction require that each of the individual working elements that constitute the construction process are optimized and considered as a system of sequential and parallel activities. The advantage of integrating the logistic backup systems facilitates an.
The program consisted of a feasibility study of the spiral blast pattern itself, together with a very preliminary design effort to es- tablish concepts and characteristics of a machine to remain at the face, performing drilling, loading, shooting, mucking, and ventilation tasks in an essentially continuous process. A literature search.
Orica buys GroundProbe tech firm. Orica will acquire GroundProbe from Crescent Capital Partners. Staff reporter 20 Dec 2017 12:04. A rock drill developed by Rockdrill Services Australia.
Aug 4, 2015 . Binary Explosive – A blasting explosive formed by the mixing of two plosophoric materials, for example, ammonium nitrate and nitromethane. Blast Pattern – The plan view of the drill holes as laid out for blasting. Blast Plan – A written procedure that details the methods and manner by which a Project blaster.
Jun 26, 2015 . In fact, because we are able to do so much with so little now, combined with the fact that almost all of the blasting and much of the drilling is contracted, quarry operations have tended to treat the unit operations of drilling and blasting as a commodity rather than a core part of their business process in the.
Coordinated Drill & Blasting. Potential integration of blasthole characteristic data such as seam and geology aspects of each hole allow dynamic blast charging and detonation timings during the blast cycle. By dynamically tailoring the blast process based on actual, “As-Drilled” hole data, blast processes can achieve higher.
Weekly or monthly safety meetings that include the blast crew, drill crew, and production crew keep employees posted as to (1) all site- specific safety procedures and (2) what is expected of them daily. Fragmentation and Moving. A proper blast design will yield adequate fragmentation, which will lower downstream costs.
01 April 2016 | Drilling & Blasting · Cost-saving Methodology for System Control of the Drilling and Blasting Process. First published in the March 2016 issue of Quarry Management as Six Sigma Blasting A new cost-saving methodology for system control of the drilling and blasting process By Anthony Konya,. Tagged in:.
Underwater drilling is the first part of the process during which drilling is done to make bore holes in the rock to place charges or explosives for blasting. The drilling (and blasting) can be done from the surface via floating pontoons and self-elevating, spudded platforms. The process also often includes overburden drilling.
Mar 23, 2015 . The drilling part of the blast hole drilling process is that most expensive part of the project. This is because it is the most important part of the project. If the initial drilling is done wrong then the future of the project could end up being a problem. Factoring in a number of considerations such as the size and the.
Instant processing of dipping data saves significant engineering time. Reducing the turnaround for load sheets means blast crews are idle for less time. BlastLogic reduces the time between drilling and loading of holes in situations when loading is shadowing the drilling. The wetness of shot and explosive product used is.
Drilling is important, a good driller (or drilling team) can make or mar a mining operation. By communicating and using some common sense, a mine or quarry can im- prove blast performance and save some money in the process. Other investigators also support the view of.  and  by submitting that drilling and blasting.
Blast Implementation. As with every step that is taken in the blasting process, safety is the first priority. To achieve this goal, one person, the blaster, is responsible for implementing the blast. Drilling the Blast Holes. Drilling accuracy is very important. Once the design is determined, the hole locations are marked on the.
Confinement determines the amount of the explosive's energy that does effective work. Confinement is provided by: ✓ Material surrounding the explosive in the drill hole. ✓ The amount of material between the drill hole and any static or dynamic free space or what we call the burden. • Burden is a critical blast dimension.
Nov 9, 2016 . During the mine scheduling process, great focus, effort and resources are allocated to remove interactions and ensure all components of the mine's overall system are given time and space to work productively. By maximising utilisation of plant and people across the schedule, peaks and troughs in demand.
Feb 20, 2018 . “The resulting savings to date are in excess of $10m per annum,” the company said, “and this has been achieved without adversely affecting excavator productivity or coal loss. In some cases, productivity has been seen to increase in addition to the cost savings made in the Drill and Blast process.” What we.
reached in 7,60m diameter tunnel excavation. It is believed that these data will be helpful for planning and management process of tunnel construction projects, especially those planned to be built in Albania where labor market carries similar features.
