Negative obstacles such as potholes and road collapses on unstructured roads in open-pit mining areas seriously affect the safe transportation of autonomous trucks. In this paper, we propose a real-time negative obstacle detection method for self-driving trucks mines. By analyzing characteristics mines, target model based Yolov4 network was built. It uses RepVGG backbone feature extraction netw...

In-pit crushing and conveying (IPCC) systems have drawn attention to the modern mining industry due numerous benefits than conventional truck-and-shovel systems. However, implementation of IPCC system can reduce flexibility introduce additional sequence requirements. This paper investigates long-term production scheduling crusher relocation plan open-pit mines using a semi-mobile high-angle con...

With a view to safe open pit mining, the anticipated water inflows in during construction are estimated. A geopermeation model is built for whole Almalyk or field. The numerical modeling of mining used Groundwater Modeling System (GMS) as most widely applied software system wide-range problem solution practical hydrogeology. test ore field features difficult geological and hydrological conditio...

This paper illustrates how Global Navigation Satellite Systems (GNSS) receivers and robotic total station instruments can be combined to provide a fully automated, accurate, efficient and cost effective survey monitoring system for large open pit mines which often reach sizes of 2km. Data processing and data screening techniques that can be used to ensure the high accuracy are reviewed and in a...

Push back design as a complex task, is one of the major steps in the open pit mines planning. Push backs can be generated by varying economic factors such as commodity price, mining cost, processing cost, etc. Another important issue in generating push backs is grade uncertainty, which can cause the problem be more complex. Conventional methods of push back design ignore grade uncertainty. To o...

While the increased automation levels of production and operation equipment have led to improved productivity mining activity in open pit mines, capacity mine transport system has become a bottleneck. The optimisation is great practical significance reduce cost improve organizational efficiency mines. In this paper, we first formulate multiobjective problem for railway scheduling by introducing...
