In order to solve problem of repeated support and damage to roof of roadway and bolt-mesh support system during the moving process of the existing advanced hydraulic support, omni-directional walking advanced powered support (OWAPS) based on auger was developed, and the shifting was carried out by means of transposition and forward movement. The problem of repeated support caused by the sequential advancement of the existing advanced hydraulic support was avoided. This report described the moving pattern and the structural characteristics of OWAPS and analyzed its mechanical characteristics. Meanwhile, the kinematics equation was concluded and a specific example was given, providing the theoretical basis for determining the walking parameters of the OWAPS. The results show that the OWAPS is easy to operate and can realize the moving functions such as forward, backward, lateral and rotating only by changing the rotation mode of left and right screw propellers. OWAPS meets requirements of easy operation and high reliability. It can solve problem of destroying the roadway roof and anchor net support system caused by the sequential advancement of the existing advanced hydraulic support.
