Abstract In the process of Open-pit mining in China, throwing blasting is an important method, which very likely to cause serious damage slope discharge field under action vibration load blasting. With background Heidaigou open-pit mine Ordos, velocity data were collected from near blast, and signal blast was analyzed by means Fourier transform obtain characteristics wave attenuation law predic...

one of the main concerns of the mining industry is to determine ultimate pit limits. final pit is a collection of blocks, which can be removed with maximum profit while following restrictions on the slope of the mine’s walls. the size, location and final shape of an open-pit are very important in designing the location of waste dumps, stockpiles, processing plants, access roads and other surfac...

The use of mixed integer programming is a modeling approach well suited to formulate the mine scheduling optimization problem for both open pit and underground mining. The resolution applied for discretizing the problem, however, has a direct effect on both the level of selectivity that can be applied to improve profitability, as well as the computational feasibility. The proposed model allows ...
