Gas explosion has always been an important factor restricting coal mine production safety The application of machine learning techniques in coal mine gas concentration prediction and early warning can effectively prevent gas explosion accidents Nearly all traditional prediction models use a regression technique to predict gas concentration
In the processing stage the mined material is transformed into usable raw material For iron ore this involves crushing the ore and then concentrating it in different ways for example by milling flotation or magnetic separation At some sites the ore is processed further and pelletised for use in direct reduced iron DRI steelmaking
For decades PM a type of fine particulate matter in large urban areas has had a profound negative impact on human health In this study spatiotemporal analysis and four machine learning methods XGBoost ANN CNN and MLR were used to assess the changes and drivers of PM concentrations in the Beijing Tianjin Hebei BTH from 2016 to 2019
STLB Gold Concentration Separator is kind centrifugal concentration equipment It can be used not only for placer gold mining but also for hard rock mining to recover the natural gold replacing amalgamation It is also used to recover gold from the old tailings Since 1985 three models of Gold Concentration Separator have been developed
