This book links innovative mining geomechanics research into the strength of closely jointed rock masses with the most recent advances in numerical modelling, creating more effective ways for predicting the reliability of rock slopes in open pit mines. ![]() Created as an outcome of the Large Open Pit (LOP) project, an international research and technology transfer project on the stability of rock slopes in open pit mines, this book provides an up-to-date compendium of knowledge of the slope design processes that should be followed and the tools that are available to aid slope design practitioners. ![]() £85, hellyhansen.Guidelines for Open Pit Slope Design is a comprehensive account of the open pit slope design process. The high dungaree design ramps up the protection and warmth in eleven sizes: from ages one to 12 years old. Helly Hansen kids’ Rider II insulated ski bib, £85Įquipped with reinforcements on the knee, bum and ankles for durability, and with stretch panels on the side for comfort, these waterproof and insulated bibs are thoughtfully designed for hardwear. Helly Hansen kids’ Rider II insulated ski bib The one-size goggles (also good for three years upwards) have a highly durable single-layer lens that is non-mirror coated, plus your child’s eyes are visible through them so you can check they’re fine without constantly removing them. Equipped with Mips for enhanced safety, it’s adjustable, very lightweight and comes in four high-visibility colours. This helmet – good for toddlers from around the age of three – leaves your child unencumbered while providing all the protection needed for a tumble on the slopes.
