地下气化火焰工作面位置微地震探测
|
摘要
在原有矿山微地震监测技术基础上,首次采用微地震技术对重庆中梁山北矿煤炭地下气化火焰工作面进行实时探测试验.利用井下三维布置的8个传感器,并通过专门定位软件来对微地震事件进行时空定位分析和处理,从而获得火焰工作面的结构和燃烧波的位态.结果表明,地下气化炉中火焰工作面为"S型事件云",长为25~32 m,厚为2.2~3.6 m;燃烧波的平均传播速度0.3 m/d,火焰工作面向上推进距离累计为25.6 m.现场实测效果表明,矿山微地震火区探测系统比现有其它物探方法更具有性能稳定、干扰噪音低、时空定位性能强的特点.
Based on the existing technique of Micro-seismic(MS) monitoring for coal mine,the technique of MS was adopted for the first time to have a real-time monitoring test on flame working face of UCG at Zhongliangshan north mine in Chongqing.With 8 sensors laid out in the well,the MS data was dimensionally analyzed and treated by special locating software to get the frame of flame working face and the situation of combustion wave.Results show that the flame working face is a "S-shaped event cloud",25~32 m in length and 2.2~3.6 m in thickness;The average propagating velocity of combustion wave is 0.3 m/d,and the flame working face moves upwards for about 25.6 m in total.The result of field trail measuring indicates that,compared with other geophysical prospecting methods,the MS monitoring on UCG fire zone has many features such as stable performance,lower disturbed noise,and good locating ability.
