A method for formation of man-caused mineral bed prescribes planning the surface for formation of man-caused bed, formation of pioneering bulk of rock mass at location of placement of the man-caused bed, with following increase of the height of the level with following formation of the upper levels of the man-caused bed till its designed contours. On the planned surface system of supports of horizontal workings is mounted, it is filled in layers with bulldozer, with mounting vibration hatches in the places of contact of horizontal and vertical supports of the workings, with mounting the vertical supports of the workings by heightand with bordering to height:,wherein- height of mounting for the vertical support of the workings, m;- height of bordering the vertical support of the workings that is taken as equal to the maximal height of the bulldozer blade, m. |
