| Abstract: | Directed at long drilling hole winding and collapsing hole, the paper, based on the analysis of the influential factors and bending mechanisms of hole crooking, introduces the design of the sleevetype stabilizer and the taper scraping bit, presents the construction program of optimization assembly drill- ing unit to tackle the long hole bend and collapse when drilling is performed, and highlights their successful uses in Nanshan coalmine in Hegang. The results show that the newly developed assembly drilling unit yields holes 71.92 m deeper on average than conventional one and what is more, the unit performs stable gas drainage. |
