A research on cooperation with the lower part of column and a stabizer with a stope back and a borehall wall

Analistiv research of impact on boring cutter cooperate with column and borehall wall have been done during drilling directional wall. Influence of location and the stabilizer sizes and feed beam on the measure of renith angle have been regarded. Analistic addictions for definitions a distance from a boring cutter to a stabilizer have been got, as well as normal constituent of the reaction backwall on a boring cutter and feed beam of column conditions for stabilization of renith angle. In term of the lead computations it was determined that the angle of stabilization is becoming lower at the time of increasing length of feed beam or stabilizer.
