煤矿氡气的研究现状及防治措施

Research status and prevention measures ofcoal mine radon gas

氡及氡子体是煤矿开采过程中不可忽视的重要气体,为了有效预防和控制氡辐射所导致的肺癌等疾病,在调查煤矿开采过程中氡存在危险的前提下,对氡气在煤岩层中的来源、赋存特点及运移规律、测定方法及防治措施等方面进行了研究,分析了矿井中影响氡及其子体含量的影响因素,同时提出了相应的防治措施,并从煤矿安全开采的角度,展望了利用氡及其子体在煤矿开采中的应用。

Radon and its daughters are important gases that can not be ignored in the process of coal mining.In order to effectively prevent and control lung cancer and other diseases caused by radon radiation,under the premise of investigating the danger of radon in the process of coal mining,the source,occurrence characteristics and migration rules,determination methods and prevention measures of radon in coal and rock strata are studied.The influencing factors of radon and its daughters in coal mines are analyzed,and the corresponding prevention measures are put forward.From the perspective of coal mine safety mining,the application of radon and its daughters in coal mining is prospected.
