In this work, a new drilling and blasting design methodology is introduced and applied at a case study mine to improve productivity. For the case study copper mine, a blast diameter of 203 mm is proposed to be used in the ore zone to meet the new required production rate of 90mtpa from 75mtpa. Currently, the Konya and Walter’s model is used to generate drilling and blasting design at a bl...

Modern graphics hardware is designed for highly parallel numerical tasks and provides significant cost and performance benefits. Graphics hardware vendors are now making available development tools to support general purpose high performance computing. Nvidia’s CUDA platform, in particular, offers direct access to graphics hardware through a programming language similar to C. Using the CUDA pla...

Cells have structure and the ability to move, thanks in part to the actin cytoskeleton, a dynamic cellular scaffolding that facilitates many cellular processes. Actin is mostly concentrated near the outer membrane of the cell, where it is involved in such processes as the formation of membrane protrusions at the leading edges of migrating cells, the movement of certain intracellular vesicles su...

Workstations make up a very large fraction of the total available computing capacity in many organisations. In order to use this capacity optimally, dynamic allocation of computing resources is needed. The Esprit project Dynamite addresses this load balancing problem through the migration of tasks in a dynamically linked parallel program. An important goal of the project is to accomplish this i...

Geologic conditions and design requirements around upstream Nachtigal Falls, in Cameroon, for the hydroelectric construction project on Sanaga River dictated close control of blasting procedures with very precise geometry to obtain safe economical excavation lines. Various techniques pre-split were used initial stage all major excavations. Hole diameters pre-splitting 89 mm, hole spacing ranged...

Dispersed iron‑containing waste makes up the lion’s share of solid technological machine‑building enterprises. Most this is still exported and buried in industrial landfills, while not only losing a signifi ant amount metal, but also causing serious damage to environment. At same time, modern state technology technologies, particular, technologies developed by Belarusian scientists for recyclin...
