Abstract

Due to the coal softness and poor gas permeability of outburst coal seam, it is very easy to cause spray holes, stuck drills, hole collapse and coal cannons during drilling. Based on the long-term on-site coal seam drilling experience, combined with theoretical analysis, the key factors that restrict the deep hole drilling of prominent coal seams are discussed in depth. The situation inside the hole after serious hole injection and its impact on deep hole drilling, the effect of entrapment in coal seams on deep hole drilling, the impact of top and bottom plates on deep hole drilling and the effect of coal cannons on deep hole drilling are analyzed. The in-depth analysis of the key factors affecting deep hole drilling can provide the important technical guidance for the efficient drilling of deep holes in soft outburst coal seams.
