    • Abstract
  • Xinzhi coal mine is a high-gas coal mine with poor permeability coal seam and low efficiency of gas extraction.As the current tension relationship between mining and excavating,according to the original plan,the extraction can not meet the requirements of time and safety production.To improve the efficiency of gas extraction and ensure production safety,hydraulic fracture technology on face 2-559 of Xinzhi coal mine was applied,which effectively improved the permeability of coal seam,improved the efficiency of gas extraction,reduced the pressure on coal seam gas,decreased the risk of coal and gas outburst,and explored a new way for the comprehensive management of coal seam gas Xinzhi coal mine.
