In order to prevent coal and gas outburst accident, through the No. 81 coal outburst prevention measures and reasonable improvement, mining face took short arm drilling gas injection technology, improved the gas extraction speed, shortened the coal seam gas drainage time effectively. By using rapid gas injection elimination outburst scheme, each outburst prevention measures used cycle time was 2.5 d, compared to the original measures, reduced 1 d, can advance 96 m per month, month tunneling efficiency increased by 40%. Under the premise of safety, the driving speed was improved.
