我国煤型铀矿资源的储量在我国铀矿资源总储量中占有一定比例。20世纪60年代后期我国开始了这类铀矿床的地下开采,在开采期间,对控制这类铀矿床地下开采中辐射危害的技术与管理措施开展了大量研究。20世纪80年代后期,因为多种原因,这类矿山被关闭。近年来,我国电力持续出现紧缺,经济建设受到严重影响,为了缓解这种局势,国家决定大力发展核电。在这样的形势下,煤型铀矿床的开采又提到了议事日程。为了使这类铀矿床地下开采中的辐射防护受到高度重视、辐射危害得到有效控制,本文介绍了煤型铀矿井辐射防护的基本知识、煤型铀矿井各类辐射对人体的危害、我国煤型铀矿井执行的剂量标准以及我国过去在煤型铀矿床地下开采中为控制辐射危害所采取的技术措施和工程管理措施。
The reserves of uraniferous coal resource account for a certain proportion of all uranium resources in China. China began to mine the uraniferous coal deposits in late 1960s. In the process of mining, much research was conducted on the control and reduction of the radiation hazards in underground uraniferous coal mine. However, such mining practice was stopped for many reasons in late 1980s. During recent years, electricity shortages have taken place from time to time. In order to alleviate the shortages, the Chinese government has decided to further develop nuclear electricity. Under such circumstances, underground mining of uraniferous coal deposits will be restarted. In order to make sure that the radiation protection will be stressed and the radiation hazards will be controlled effectively in the underground uraniferous mine, this paper gives the basic knowledge of radiation protection, describes the radiation hazards to the miners and our national dosage standards implemented in the underground mine, and, on the basis of summing-up of the past experience in mine radiation protection, presents the technical and management measures for controlling and reducing radiation hazards.
