Gas Treatment for Gassy Working Face in Complicated Geological Structure Region During the Initial Mining

Safety control of working face during the initial mining and blasting down the roof is the key to guarantee safety production under the condition of complicated geological structure, high gassy, spontaneous seam. Though the following measures, adjusting ventilation system at working face, extracting gas from gob area by high drilling, laying pipes under the lower corner, inserting the pipes among the holder, monitoring the safety, we achieve the safety mining at working face during initial mining and discharging and at downward ventilation section, and gas safety management.
