PROBLEM TO BE SOLVED: To impart an extremely easy drilling positioning control mechanism to an existing rock drill loaded truck having no servo mechanism without the need for large-scale reform. SOLUTION: Before drilling, the coordinate and attitude condition of the rock drill loaded truck is measured. Thus, the installation coordinates and directions of cameras 9A, 9B are known, camera images picked up for a working face are displayed on a monitor 2, working drill points P, P are marked on the monitor 2 through signals from a computer 3, and rear end positions K, K of a guide shell 12 are marked corresponding to the drilling attitude. A drilling bit 13a of a rock drill 13 is set corresponding to the marked working drill point P and the guide shell 12 is controlled to be moved so that the rear end of the guide shell 12 corresponds to the marked point of the guide shell rear end position K.
