乌达矿区上覆火区测氡法探测技术的应用研究

Study about Application of Radon-measuring Method Detection Technology in the Over-fire Area of Wuda Mining Area

地下煤层自燃形成的火区是矿井五大灾害之一,其火源隐蔽、不易扑灭,给矿井的安全生产和当地的生态环境带来巨大的威胁,同时也会造成煤炭资源的大量损失。在生产矿井中,由于地下火区和采空区、小窑区往往联系在一起。而且,我国的煤矿一般都在地形复杂的山区,要克服地形、地下工业游散电流、地下地磁物质的影响,测氡法就显示出它的优势。它简单易行、几乎不受地形影响,有着其它物探方法所不能比拟的优点。

The fire area formed by spontaneous combustion of underground coal seam is one of the five major disasters in coal mine.Its fire source is concealed and difficult to extinguish,which brings great threat to mine's safety production and local ecological environment,at the same time,it will cause a large amount of loss of coal resources.In production mines,underground fire areas are often linked with goaf and small kiln areas.Moreover,the coal mines in our country are generally located in the mountainous areas with com?plicated topography.To overcome the influence of topography,underground industrial swimming current and underground geomagnetic material,radon-measuring method shows its advantages.It is simple and easy to use,almost unaffected by topography,and has more advantages than other geophysical methods.
