High level borehole gas drainage is an important means on the corner and surface gas transfinite governance, the Xinan Coal Mine as the research background, analyzes the effect of high level borehole gas drainage effect of key factors, through theoretical analysis and calculation, field drainage experiment of high gas drainage drilling end hole of the reasonable horizon. Study concluded that: high level borehole end hole reasonable horizon should fall from the roof 15m-28.1m, from airway wall of roadway distance should be controlled in the range of 30.6m-44.5m.
