One of the key technologies on fully-mechanized working faces is how to prevent transporters and supports from jumping and slipping.The paper briefly analyzes the cause bringing about the jumping and slipping of transporters and supports,and proposed the measures preventing them from falling and slipping on fully-mechanized working faces in combination with own experience.The study offers guidance for the study of the scientific control on falling and slipping of transporters and supports as well as high productivity on fullymechanized working faces.
