| 摘 要： | 大同侏罗纪煤层是易自燃发火煤层,采用黄泥灌浆进行防灭火,工艺简单,效果好。但是,浆液在采空区中的扩散范围往往无法准确确定,跑浆、串浆现象严重,造成大量的注浆材料浪费,延长了注浆时间,影响注浆效果。利用瞬变电磁法探测浆液扩散情况,定位准确,效果好,值得借鉴和推广。

| Abstract: | Jurassic coal of Datong is coal easy to turns into spontaneous combustion and inflammation.It is simple process to use wong grouting to prevent and extinguish fire and you can get good effect.But it offen can not accurately determine the spread range of grout slurry in extraction gap.The phenomenon of running pulp and string pulp is serious.A large number of grouting material is wasted and grouting time is extended.Thus the grouting effect is affected.You can get accurate positioning and good effect to use Transient electromagnetic phase method to probe the spread situation of grout slurry.So this method is worth learning and promotion. |
