抚顺东露天矿开采过程粉尘污染与防治措施

Dust Pollution and Prevention Measures in the Mining Process of Fushun East Open-pit Mine

露天开采中产生的大量粉尘对作业环境、设备及人体健康均构成重大危害。为促进露天采场更好地落实绿色矿山建设精神,保护设备和人体健康,以抚顺东露天矿为例,介绍了汽运粉尘是采场粉尘的第一来源,占全矿总产尘量的91.33%;钻机粉尘、电铲粉尘、爆破粉尘、推土机扬尘、凿岩机产尘也是采场大气粉尘的重要来源。并提出了相应防治措施,其中运输道路除尘主要根据季节和降雨状况进行洒水车洒水除尘;钻机除尘采用干、湿2种除尘方式;其他除尘主要采用洒水方式。

A large amount of dust produced in open-pit mining poses a significant hazard to the work-ing environment,equipment and human health.In order to promote the open-pit mine to better implement the spirit of green mine construction,and protect equipment and human health,taking Fushun East Open-pit Mine as an example,it is introduced that automobile dust is the first source of dust in the stope,account-ing for 91.33%of the total dust production in the whole mine.Drilling dust,electric shovel dust,blasting dust,bulldozer dust,and rock drill dust are also important sources of atmospheric dust in the stope.The pre-vention and control measures are proposed accordingly.The dust removal of the transportation road mainly use sprinkler water dust removal based on the season and rainfall conditions.The dust removal of the drilling rig adopts two dust removal methods of dry and wet,and the other dust removal mainly adopts the sprinkler method.
