The Application of New Coal Rock Identification Technology in Unmanned Longwall Face of the Thin Coal Seam

Through analysing the critical technology of how to achieve unmanned operation in full mechanized longwall face,which called the technology of identify coal and rock,we introduced a new technology to identify coal and rock based on noise.It is also applied in longwall face of the thin coal seam by a native mine.From the conclusion of test with other machines underground,this critical technology will absolutely complete unmanned operation and unmanned monitor in full mechanized work face.
