Single Lane Tunnel and gas outburst advanced prediction method

The present invention discloses a method for single-lane heading Advance Prediction outburst by boring head and at two gas return air, the wind speed real-time data monitoring gas probe is protruded ahead prediction. The establishment of roadway gas emission amount of hours, days and weeks the average amount of change as early warning indicators to determine the roadway by pouring status indicators through the formation of gas near point A point return airway, monitoring one hundred meters; boring head set up close to Point B, hours total emission monitoring of gas, the amount of daily, weekly average change as an early warning indicator, change the amount of emission by the head of the local gas indicators for monitoring the excavation. The invention is confirmed by the interaction of two differences indicators, in line with the geological characteristics of the gas outburst, combined with the existing coal mine safety monitoring system, a single-stage gas outburst prediction lane heading into a small, forecast timely, ahead of forecast features, at home and abroad to fill the technology gap.
