【摘要】：通過(guò)對(duì)鄂爾多斯伊金霍洛旗納林陶亥煤礦區(qū)一年內(nèi)大氣降塵監(jiān)測(cè)樣點(diǎn)的數(shù)據(jù)分析,研究了煤礦區(qū)大氣降塵的特征,評(píng)價(jià)了煤礦區(qū)大氣環(huán)境的污染程度。結(jié)果表明:從一年內(nèi)降塵量月平均分布特征來(lái)看,年內(nèi)降塵量最高的月份為12月,降塵量最高達(dá)到128.94t/km~2·30d,最低月份為4月,僅為42.86t/km~2·30d,冬春季降塵量明顯高于夏秋季;從降塵區(qū)域分布特征來(lái)看,工業(yè)區(qū)、采坑及周邊、交通區(qū)是主要的降塵分布區(qū),年度平均降塵量在88.79-149.65t/km~2·30d之間,明顯高于居民區(qū)的77.83t/km~2·30d和農(nóng)業(yè)區(qū)的73.93t/km~2·30d;從降塵量的空間分布特征來(lái)看,距離采礦核心區(qū)域0-1000m范圍的年均降塵量最小為62.36t/km~2·30d,1000-3000m范圍內(nèi),大氣降塵均量達(dá)峰值為128.69t/km~2·30d,隨距離的變化降塵量呈衰減趨勢(shì);對(duì)比自治區(qū)其他省份降塵限值要求,研究區(qū)明顯高于其他地區(qū),采煤活動(dòng)已對(duì)伊金霍洛旗納林陶亥礦區(qū)造成了嚴(yán)重的粉塵污染,采煤活動(dòng)是大氣降塵的主要來(lái)源。
[Abstract]:The characteristics of atmospheric dust fall in the coal mine area are studied by analyzing the data of the monitoring points of atmospheric dust fall in the Nalintaohe coal mine area of Erdos Ijinhuoluo Banner within one year. The pollution degree of atmospheric environment in coal mining area is evaluated. The results show that the month of annual dust fall is December according to the monthly average distribution of dust fall in one year. The highest dust fall was 128.94 t / km ~ (-1) 2.30d, and the lowest month was April (42.86 t / kg ~ (-1) 2.30d). The dust fall in winter and spring was obviously higher than that in summer and autumn. According to the regional distribution characteristics of dust fall, industrial area, mining pit and surrounding area and traffic area are the main distribution areas of dust fall, the average annual dust fall amount is between 88.79-149.65t / km ~ (-1) 2.30d. It was significantly higher than that of 77.83 t / kg / kg in residential areas and 2.30 days in agricultural areas respectively, and was significantly higher than that of 77.83 t / kg / kg in residential areas and 2.30 days in agricultural areas. According to the spatial distribution characteristics of dust fall, the minimum annual dust fall within the range of 0-1000m from the mining core area is within the range of 62.36t / kg / kg 2.30dg ~ 1000-3000m. The average amount of dust fall in the atmosphere reaches the peak value of 128.69 t / km ~ (-1) for 2.30 days, which tends to decrease with the change of distance. Compared with other provinces in the autonomous region, the study area is significantly higher than other areas, coal mining activities have caused serious dust pollution in Nalintaohe mining area of Ijin Horo Banner. Coal mining is the main source of atmospheric dust.

【正文快照】： 大氣降塵是大氣中粒徑大于10μm的固體顆粒物的總稱(chēng)[1-2]。隨著我國(guó)城鎮(zhèn)化、工業(yè)化進(jìn)程的推進(jìn),降塵量明顯增加,大氣降塵成為大氣污染物監(jiān)測(cè)的主要指標(biāo)之一。以往的研究大多將大氣降塵與降塵中攜帶的重金屬污染物結(jié)合起來(lái)分析,重點(diǎn)探討降塵重金屬元素的污染特征等問(wèn)題[3-6],并，
