| Abstract: | Based on the condition that it is difficult to drill hole along the coal bed in complex soft coal seam,Qinan Mine carried out the test of excluding dust by spiralling and wind pressed,using CMS1-6200/80 deep-hole drilling vehicle.With this technology,Drilling achieved an average hole depth of 142.7m,the concentration of gas drainage reached 30%~ 40%. |
