ERG Easy Slot Master Video 3
Longitudinal longhole retreat is a branch of the generic mining method known as sublevel stoping and often requires the development of a rise or slot prior to production blasting. Easy Slot eliminates thee need for raise bore or burn cut blast to create the rise or slot. Easy Slot is less expensive quicker to install and provides a bigger slot thus a better production blast.

BLASTOP -  Underground Blast Designer for Stope Blasting
Designs editable Ring Blast pattern for Stope based on geological and geotechnical conditions of the Stope. The designer has the ability to generate charging sheet and drilling sheet, import existing drilling sheet, predict fragmentation and ground vibration. It also allows the user to perform a comparative study of blast results with respect to the changes in geotechnical details in the field.

DD Grout Plugs -  Stemming Plug Installation with captions
This animation shows the installation of the cement Stem Boss Plug, a method of stemming for underground hardrock mining that was developed by DD Grout Plugs. Testing on these plugs has shown a minimum resistance achieved of 9 Tonnes, unprecedented for stemming particularly in upholes and several orders of magnitude stronger than anything else available. This product is being updated with prototypes being made at present. Stemming Plugs can be used for slashing shots to protect mining infrastructure from rifling, VCR rising, and to improve fragmentation in longhole open stoping or sub-level stoping mining methods. These are available for 76mm to 102mm upholes, and will work equally well in downholes. For more information please go to www.ddgroutplugs.com.au or email us at [email protected] (Patent Application No.'s PCT/AU2013/000489 and Australia 2013903545)

What is retreat mining?
Program version at 10.43.31 HEADLINE: What is retreat mining? CAPTION: An official at MSHA describes the mining process known as 'retreat mining' following concerns that the Utah miners were engaged in the often-dangerous form of mining. The CEO of the mine in Utah denies the trapped men were involved the process.

Horizen Statement on Mining Algorithm
The Horizen (ZEN) team carefully evaluated the pros and cons of changing from the existing Equihash Proof of Work mining algorithm. The major concern of the team, as well as much of the Horizen community, was maintaining the security of the project.  Horizen is a project that is sensitive to the concerns and desires of the community and worked to determine if there was a clear desire to change the mining algorithm. It was difficult to determine, but what was clear was that people did not want further 51% attacks.  Read our full statement here: https://blog.zencash.com/horizen-statemen…mining-algorithm/ ‎

What is RAISE BORER? What does RAISE BORER mean? RAISE BORER meaning, definition & explanation
What is RAISE BORER? What does RAISE BORER mean? RAISE BORER meaning - RAISE BORER definition - RAISE BORER explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. A raise borer is a machine used in underground mining, to excavate a circular hole between two levels of a mine without the use of explosives. The raise borer is set up on the upper level of the two levels to be connected, on an evenly laid platform (typically a concrete pad). A small-diameter hole (pilot hole) is drilled to the level required; the diameter of this hole is typically 230mm - 445mm (9" - 17.5"), large enough to accommodate the drill string. Once the drill has broken into the opening on the target level, the bit is removed and a reamer head, of the required diameter of the excavation, is attached to the drill string and raised back towards the machine. The drill cuttings from the reamer head fall to the floor of the lower level. The finished raise has smooth walls and may not require rock bolting or other forms of ground support. The one of impressive use of raise boring is a 7.1 m diameter shafts for Sasol's Middelbult and Bosjesspruit Mines in South Africa. Masterdrilling is currently the world's biggest raise boring firm with operations throughout all 7 continents. The boxhole borer (or machine roger) is a variant of a raise borer that is used when there is not enough space on the higher of the two levels to be connected. The boxhole borer is set up on the lower level, drills a pilot hole as a guide, then drives the reamer bit along the pilot hole from the lower level to the upper. Precautions have to be taken to redirect falling drill cuttings away from the machine, and to reinforce the drill string.
