摘要
针对采场高强度围岩活动引起瓦斯异常涌出,造成正常生产的工作面、上隅角和回风巷瓦斯浓度超限的这一现象,以6211(3)工作面为例,利用微震监测技术分析了采场高强度围岩活动的能量频次及发生地点,结合现场瓦斯浓度实测,研究了高强度围岩活动与瓦斯异常涌出之间的关系。
Aiming at methane abnormal emission caused by high intensity activity of surrounding rock leading to methane transfinite of the normal working face、upper corner、ventilation roadway, studied the relation between high intensity activity of surrounding rock and abnormal emission with the example of6211(3) working face and the using of the micro seismic monitoring technology to analyse the frequency time and place of high intensity activity of surrounding rock.
