In metal mines containing traces of radon, one of the main reasons of polluting the in-take air current usually comes from the emanation and accumulation of radon in the mined-out area. In this paper the accumulation and varaition of radon in the mined-out area are theoretically discussed and calculated, and practical observations and verifications are described. The reason for the variation of radon concentration in the mined-out area is made clear, the method of prevnting the radon contamination of in-take...

In metal mines containing traces of radon, one of the main reasons of polluting the in-take air current usually comes from the emanation and accumulation of radon in the mined-out area. In this paper the accumulation and varaition of radon in the mined-out area are theoretically discussed and calculated, and practical observations and verifications are described. The reason for the variation of radon concentration in the mined-out area is made clear, the method of prevnting the radon contamination of in-take air current by changing the ventilation pressure as well as the condition of pressure distribution is suggested, and the effective result accomplished in mines by using these methods is also noted.

在含铀金属矿山,采空区中氡的析出和积累常常成为污染矿井大气的主要氡源,本文对采空区中氡的析出和积累作了理论上的论述和计算,并进行了实地考查和验证。阐明了采空区中氡浓度增高和污染井下大气的原因,提出了借助于通风压力分布以防止采空区中氡污染矿井大气的方法,并介绍了这些方法在矿山使用中所取得的实际效果。

On the basis of the field survey and a great number of testing data thus monitored, this paper presents the qualitative and quantitative assessmnt of the polluted mining environment in the mid-southern Shandong Province, with the following points as grade Ⅰassessment factors: the collapse and land subsidence in the gob, the "three wastes" and polluting sources in the mining industry, the surface water, underground water and atmosphere. The methed for the calculation of the equiscalar pollution loading ratio, the single index number methed, and the aggregative index number methed are all applied to the verification of the major polluting sources, pollutants, and pollution types and order. In this way, the number of waste materials and liquids per 10 000 mining preduction value is given in this paper.

在实地考察并收集大量监测数据的基础上,以采空区塌陷及地面沉降、矿业“三废”及污染源、地表水、地下水及大气为一级评价因子,对鲁中南地区矿业环境污染状况进行了定性与定量评价.通过等标污染负荷比计算及单一指数法和综合指数法,查明了该区的主要污染源、污染物和污染类型,并给出了矿业万元产值废物和废液产生量.试图从资源环境联合评价角度,提供一个矿业环境评价的具体例证,包括可供借鉴的评价方法、数据和结论.该项研究的目的在于摸清国情,为优化矿业环境生态系统及可持续发展服务.
