Detecting coal content in gangue via machine vision and …
However, online detection of the coal content in gangue is currently unfeasible. A high coal content in gangue not only leads to a decline in the yields of clean coal but also reduces the economic benefits of an enterprise. Usually, coal content in gangue is measured by sampling and the float-sink test; this requires considerable time …
