Mineral and metallurgical processing are crucial within the mineral value chain. These processes involve several stages wherein comminution is arguably most important due to its high energy consumption, impact on subsequent extractive processes. Several geological properties of orebody efficiency metallurgy; scholars have therefore proposed deal with uncertain ore feed in terms grades rock type...

Mine geological disaster is a complex non-linear system. The traditional prediction model has the disadvantages of low accuracy and poor reliability. In order to solve this problem, open-pit mine slope displacement taken as research object. Based on new algorithm extreme learning machine (ELM), intelligent sparrow search (SSA) are introduced determine weights thresholds input layer hidden ELM. ...

Abstract Coal mining in China is continually increasing, and the associated emitted coal mine dust of growing environmental occupational concern. In this study, deposited (DD) was analysed three different regions an active, highly-volatile bituminous open-pit Xingjian Province, Northwest China: working fronts, tailings handling sites, road traffic sites. Samples were for particle size, geochemi...
