摘要
发生矿井事故以后,对被困人员的快速定位是事故救助的关键所在。地下被困人员的活动或者连续锤击产生的信号可以在地面铺设检波器进行监听,通过对这些信号的研究,建立了一个模型,合成一个多次激发的地震记录,并对这种记录进行互相关成像。理论证明此方法可行,且定位效果明显。
It is the key for the accident relief to locate trapped miners speedily after a mine accident. The activities of the trapped miner or continuous hammering would generate a signal which would be detected by geophones placed on the surface. By studying these sig- nals, a model was established and a seismographic record stimulated repeatedly was synthesized. Cross - correlation image was carried out by using such records. Theoretical proof that this method is feasible and .positioning effect is obvious.
