摘要
结合3012工作面瓦斯异常涌出实际情况,分析大气压力变化与工作面瓦斯涌出作用机理,通过实测研究表明,受季节、温度及天气影响大气压力变化可达10 h Pa,大气压力的变化与矿井采空区瓦斯涌出呈反比例关系。研究结论为矿井瓦斯异常涌出预测预报及治理方案提供依据。
Based on the actual situation of abnormal gas emission at 3012 working face, this paper analyzed the atmospheric pressure change and gas emission mechanism at working face. The results showed that the change of atmospheric pressure could reach 10 h Pa affected by season, temperature and weather. The change of atmospheric pressure and gas emission in the minedout area were inversely proportional to each other which provided references for pre-monitoring and warning of abnormal gas emission and the treatment schemes.
