土壤中α测量在煤矿隐伏构造探测中的应用

Soil α Measure Application in the Detection of Mine Concealed Structures

由于陷落柱、断裂等构造对完整地层的破坏,放射性物质氡随构造破坏带上移到地表,从而形成放射性氡元素含量的差异的"异常晕",利用α数字闪烁辐射仪来测量放射性的强弱,在探测范围内圈出"异常区",对于探测煤矿中的隐伏构造有重要意义。土壤中α测量法是采用天然放射性探测方法之一,具有安全、放射性小、无污染等优点,其应用有重要意义。

Because of the collapse column,fault and other structural damage to the complete formation,radioactive material radonwith the structure damage brought up to the surface,forming a radioactive elements of radon content difference of abnormal＂halo＂,using the α numeric scintillation radiometer to measure the strength of the radioactive,within the scope of the detecting circle ＂abnormal＂area,which had important significance to detect concealed structures in coal mine. αmeasurement in soil was one of the natural radioactive detection method,had the advantages of safety,small radioactive,no pollution,was important for its applications.
