Problems of Directional Drilling in OKD, DPB, a.s.
Application of directional drilling in underground coal mines is well known from Australia or USA, this method is used especially for gas drainage and coal seam exploration. The paper deals with trajectory control of boreholes drilled in underground of Ostrava-Karvina coal mines. Utilisation of indi...
