摘要
所有主要的露天采矿活动都会产生粉尘,在露天煤矿产生粉尘的主要业务有钻孔,爆破,装载,卸载,和运输。灰尘不仅降低了矿区周围环境空气质量,还会对人产生严重的健康危害。因此,评估不同区域粉尘的产生量对提高人体健康水平至关重要。文章研究分析了煤矿区特定地点的可吸入粉尘量数据,地点涵盖了各种采矿活动包括表土转运,堆场,装煤,钻井,输煤。结果表明,钻井作业会产生较高浓度的粉尘,因此,钻工会有较高的呼吸类疾病致病风险。
All major opencast mining activities produce dust. The major operations that produce dust are drilling, blasting, loading, unloading, and transporting. Dust not only deteriorates the environmental air quality in and around the mining site but also creates serious health hazards. Therefore, assessment of dust levels that arise from various opencast mining operations is required to prevent and minimize the health risks. To achieve this objective, an opencast coal mining area was selected to collect respirable dust measurement samples. The study covered various mining activities in different locations including overburden loading, stock yard, coal loading, drilling, and coal handling plant. It was concluded that, drilling operations produce higher dust concentration levels and thus, drill operators may have higher incidence of respiratory disorders related to exposure to dust in their work environment.
