NOTE: Although this video shows an up-close look at the blasting process, NEVER go near an active surface mine or blast site without Federal training and permission. FYI, the white bags are Emulsified Ammonium Nitrate. The read cap is TNT and the silver rod that is connected to it by the yellow wire is the blasting cap, it's what ignites the shot. The white pebbles that are emptied into the blast holes by the powder trucks are the main explosive- "ANFO" or Ammonium Nitrate, which is a mixture of fertilizer and diesel fuel. Once the holes are filled with explosives, rock fines or "stemming" is pushed back in the holes and packed down to keep the explosives under pressure. After all the holes are loaded and rigged up, it's time for the fireworks! And remember kids, don't try this at home! Want to see more Blasting?

The Australian Centre for Geomechanics has developed this safety training DVD for underground metalliferous mine workers. To purchase this product or find out more information, visit http://www.acg.uwa.edu.au/shop#trainprods Overview All underground mine workers will be exposed to drilling and blasting processes. The aim of this new DVD is to provide workers with the critical knowledge on drilling and blasting to aid appreciation of the importance of these mining processes and their related hazards. The DVD features an introduction to the rock breaking process in mining, followed by a section on how to handle, store and transport explosive products. The third part of the DVD covers development drilling and blasting practices; and the fourth part discusses production drilling and blasting. Target Audience Underground mine workers - the need to identify the potential hazards of working near or with explosives, and the protocols of re-entering a working area after blasting. Workers responsible for development and production drilling and blasting activities. This DVD will review drilling and blasting fundamental concepts that are critical to achieving optimal rock breaking outcomes. All industry stakeholders - those keen to learn more about drilling and blasting in underground mines. Project Sponsors: Barrick Gold of Australia; BHP Billiton Olympic Dam; Dyno Nobel Asia Pacific; Gold Fields Australasia; Newmont Asia Pacific; Orica Mining Services; Xstrata Zinc.

Are civil and military explosives the same? In other words, are we using the same explosives in mining and warfare? Well, yes and no. From the ninth century AD (though the historians are still uncertain about the exact date of its invention) to the mid-1800’s, black powder was the only explosive available. A single type of explosives was therefore used as a propellant for guns and for blasting purpose in any military, mining and civil engineering application. The Industrial Revolution carried new discoveries in explosives and initiation technologies. A specialization principle, therefore, operates between military and civil application of explosives thanks to new products economics, versatility, strength, precision or capability to be stored for long periods of time without significant deterioration. https://www.thebalance.com The following factors shall be considered to determine the blast area: • Geology or material to be blasted, • Blast pattern, • Burden, depth, diameter, and angle of the holes, • Blasting experience of the mine, • Delay systems, powder factor, and pounds per delay, • Type and amount of explosive material, and • Type and amount of stemming. #blasting #mining #industry #coal

The Advanced Blast Firing Sequence Design functionality in GEOVIA Surpac™ 6.7.1 allows users to graphically tie, untie and edit blast holes in a given blast pattern so that the blast holes can be fired as per a desired sequence. This feature enables increased flexibility and customizability when designing a firing sequence, which means users can combine different, multi-directional blast patterns and watch these patterns come to life via the animation slider. Additionally, users can edit inter-hole delays to adjust the amount of explosives being fired at a given time to minimize vibrations. The feature also makes it easy to examine the firing angle using the animation slider, and prepare a firing plan for Autoplot. Watch our previously recorded webinar on using the advanced blast firing sequence in Surpac.

Blasting plays a very important role in most mining operations, quarrying as well as civil engineering projects such as road and dam construction. It helps in fragmenting the rock before loading, transporting, crushing or milling operations. https://youtu.be/O6pOxIFq8XM Jumia Kenya https://www.jumia.co.ke/ Amazon https://www.amazon.co.uk/

Raise drilling is used to create large drill holes -- up to 7.6 meters in diameter. The holes, or tunnels, are used to connect mine shafts, power plant tunnels or channels for rainwater and surplus water, as well as for ventilation between different levels in a mine. This type of drilling is performed in two stages. First you drill a smaller pilot hole and then you swap the smaller drill bit with a reamer. The reamer is equipped with reels made of hardened metal which have the same diameter as the final hole. The hole is expanded as the reamer crushes the rock using both pressure and rotation. Raise drilling can be used for holes and tunnels of up to 1100 meters in length, which makes this method very practical for many applications. https://engineers-channel.blogspot.com/p/raise-drill.html

The nature of open cut mining requires exposure of machinery and personnel to what is known as the high wall of the open cut pit. During operations such as drilling and loading holes in preparation for blasting, rockfalls from the high wall are frequent. In response to the need to remove personnel from the high wall area, Grange Resources, in association with pitt&sherry, have developed a remote shot charging unit. This video demonstrates the aforementioned risks and solution that the remote shot charging unit provides. #indianminerology #indianmineralogy #mining #gastesting #coalmines #miningknowledge #miningtechnology #coalindiajob #miningengineering #miningvideo #miningcourse #mining #aksuniversity #trandingnow #gtexamquestion Follow us on our facebook page 👇 Facebook page link 👇 📺http://www.facebook.com/indianminerology अगर आपको हमारा वीडियो पसंद आया तो हमारे चैनल को लाइक शेयर करें ! अगर कोई सुझाव भी सवाल हो तो कमेंट करें और हमारे चैनल को सब्सक्राइब करें और बैल आइकॉन 🔔🔔🔔को जरूर दवाएं ताकि इस चैनल पर कोई भी वीडियो अपलोड होने पर सबसे पहले आपको जानकारी मिली ! 👍👍धन्यवाद👍👍
