Optimization and Improvement of Dust Removal System of Continuous Shearer in Daliuta Coal Mine
, 2020 In view of the fact that the existing continuous coal mining machine dust removal system can not solve the problem of dust overrun during the operation of the driving face of Shendong Daliuta Coal Mine, we point out the design defects of the existing ...

Geological Journal, EarlyView.The study outlines the tectono‐sedimentary evolution of the İnegöl Basin in north‐western Anatolia. Basin formation was controlled by interacting extensional and strike‐slip fault systems linked to uplift of the Uludağ Massif. Terrestrial sedimentation from the Miocene to Pleistocene is reconstructed using abundant fossil mammal assemblages that ...
