The authors presented the approaches for a quantitative estimation of the additional resistance value of moving the pipeline in case of emergency on the collapsed wall of the borehole in absence of mud during the pipeline construction using the horizontal directional drilling method. In addition, the distribution and ratios of pressures, arising from the side of soil mass and drilling mud on the wellbore are found and shown to identify the potentially dangerous areas of the well arch collapse.
