Introduction: The number of backcountry skiers and snowboarder surged in the last years, especially during COVID-19 pandemic, as ski resorts shut down. Inevitably, this led to an increase avalanche-related injuries death. As avalanche rescue device, airbags are increasingly becoming part standard winter mountaineering equipment. Method: This study provides a review available data updated perspe...

Purpose. The research purpose is to substantiate the rational parameters of innovative container technology for transporting mine rocks in open pits with account technological advantages. Methods. winding machine normal operation was determined by calculation performed. metal structure designed environment Compass-3D software complex. structural elements were tested using computer modeling meth...

The limpet radula is a feeding organ, which contains more than 100 rows of teeth. During their growth the teeth mature and advance in position along the radula. The simpler doccoglossan radulae operate by grinding rocky substrates, extracting the algae by rasping and scraping with the teeth functioning as shovels. Less is known about the rhipidoglossan radulae, used as rakes or brooms that brus...

The deployment of large machinery for low cost, bulk surface mine production operations has resulted in High-Impact Shovel Loading Operations (HISLO). In extreme cases, shovels load large dump trucks with 100ton (or more) passes generating high-impact forces under gravity. HISLO generates high-frequency shockwaves that cause severe truck vibrations exposing operators to Whole Body Vibrations (W...

Truck and shovel operations comprise approximately 60% of the total operating costs in open pit mines. In order to increase productivity and reduce the cost of mining operations, it is essential to manage the equipment used with high efficiency. In this work, the chance-constrained goal programing (CCGP) model presented by Michalakopoulos and Panagiotou is developed to determine an optimal truc...
