This paper presents a mechanical control method for precise weeding based on deep learning. Deep convolutional neural network was used to identify and locate weeds. A special modular weeder designed, which can be installed the rear of mobile platform. An inverted pyramid-shaped tool equipped in shovel out weeds without being contaminated by soil. The weed detection implemented an embedded syste...

While doing some volunteer work recently, I was removing broken sidewalk stones and digging down a few inches to eventually add sand new pavers. surprised find an underground wire from the building feeding lamppost distance away. Fortunately, wasn’t damaged by shovel, but this definitely electrical hazard, it could have resulted in injury. The local codes require be buried 24 (60 cm) or, if pro...

Sliding wear of bulk handling equipment (e.g., shovel bucket, mill and transfer chute) can be dramatically reduced by using a convex pattern surface compared to flat surface, adjusting the flow behavior particles moving along surface. To study effect particle size relative dimensions coarse graining technique is applied. Comparisons between surfaces illustrate two-sided on sliding wear. The ind...

Truck-Shovel fleet, as the most common transportation system in open-pit mines, has a significant part of mining costs, for which optimal management can lead to substantial cost reductions. Among the available dispatch mathematical models, the multi-stage approach is well suited for allocating trucks to respected shovels in a dynamic dispatching program. However, with this kind of modeling sequ...
