Currently acquiring mine shifts in partial fulfilment of a blasting certificate. I assist technical officers with their daily duties at opencast coal mines.I perform blast audits regularly, at various collieries around the Witbank area, to ensure acccurate blasts.I have great exposure to the practical application of both shock tubes and electronic blasting systems.
Feb 21, 2019 In 1963, five key ratios were presented that could be applied throughout surface blasting conditions to give comparisons between multiple types of operations. Richard Ash denoted these as k-factors, which were the starting point for simplistic blast design. These could easily be used to get approximate starting points for various situations.
Nov 10, 2017 AEL also supplies a comprehensive range of packaged explosives. AEL deploys in-house engineering competency to design and build Mobile Manufacturing Units MMUs for surface and underground mining, bulk emulsion manufacturing plants and modular initiating systems assembly plants.
3.1 Blast design and general safe blasting practice. 3.2 Ground vibration, one of the major concern issues. 3.3 Airblast, also a major cause of concern. 3.4 Unwanted side effects such as fly rock, after blast fumes and dust.

less wastage of explosive energy in blasting, less throw of materials, and reduction of blast vibration resulting in greater degrees of safety and stability to the nearby structures. Development of a Blast Optimization Model Selection of proper explosive in any blasting round is an important aspect of optimum blast design.

by AEL and other organisations to create a pre-split design which delivers a stable highwall for the life of that part of the mining operation. It will look at the need to adapt and change the way, size and direction of the production blasts as the mining phase approaches the highwall position for which a pre-split has been created.

In an open-pit mine or quarry, a drone survey refers to the use of a drone or UAV unmanned aerial vehicle equipped with a downward-facing RGB camera to capture images of a site from different vantage points. Out of these images, a photogrammetry software can recreate geo-referenced 3D maps, contour lines digital terrain models or digital surface models of the mining

Depending on the design of the form, either the top, troweled side or the bottom or form side may be the exterior of the building. 3 Troweled Floors - Painting concrete floors is a difficult and painstaking job. Most failures occur because the mason over-trowels the surface, bringing weak slurry of water and cement to the surface.
