铀矿井下空气质量的广义对比加权综合标度指数评价

An evaluation model for air quality in underground uranium mines based on integrated scale index on weights of generalized contrast

对地下铀矿山井下空气质量传统评价方法的缺陷进行了分析,在此基础上,根据空气中有害物浓度成等比变化、它们对空气质量造成的危害程度成等差变化的原则,确定了铀矿井空气质量的评价指标,建立了铀矿井空气质量的广义对比加权综合标度指数评价模型。该模型克服了传统评价方法主要从辐射危害的角度进行评价的局限,能综合评价铀矿山井下空气的质量。采用该模型对某铀矿井4个用风点的空气质量进行了评价,获得了4个用风点空气质量综合评价等级和应采取的相应的对策。评价结果能为铀矿井通风系统的设计和空气质量的安全评价提供参考。

The shortcomings of traditional methods for evaluating air quality in underground uranium mines are analysis. Based on the analysis results and the principle that the concentration of the taminants in a mine varies in a constant ratio and the degree of their hazard varies in an arithmetic gression, the evaluating indicators were determined for the air quality in a uranium mine, and an con pro eval uation model was proposed for the evaluation of the air quality in a uranium mine based on integrated scale index on weights of generalized contrast. The model overcomes the shortcoming of traditional methods that the radiation hazard is considered mainly in all these methods. The model was used to e- valuate the air quality of four places in an underground uranium mine, the grade of the air quality and the correspondingmeasures for controlling the air quality in the four places are determined. The evaluation results show that the model is applicable to the design of a ventilation system for an underground uranium mine and the evaluation of the air quality in the system.
