某市区矿井职业卫生现状调查研究

Investigation and research on occupational health status in an urban mine

目的了解某市区非煤矿井职业卫生现状,分析非煤矿井采用机械作业后职业危害变化情况,为非煤矿井职业健康安全提供数据支撑。方法通过现场采样检验和现场测定职业病危害因素浓度(强度),并收集2017-2018年非煤矿井职业卫生现状评价报告的检测检验数据,进行统计学分析,综合分析不同采矿方式的矿井职业卫生现状。结果采用凿岩机打眼的非煤矿井,井下氮氧化物和碳氧化物浓度较非机械作业矿井高,打钻工人实际接触噪声强度有所降低,但采矿工作面噪声强度变化不大。结论采用炮采和机械作业的非煤矿井井下工作场所,在机械通风不良的情况下,易发生急性职业中毒。

Objective To understand the occupational health status of non-coal mine in a city,analyze the changes of occupational hazards after mechanical operation in non-coal mine,and provide data support for occupational health and safety of non-coal mine.Methods The concentration(intensity)of occupational hazards factors was measured by on-site sampling and inspection,and the data of occupational health status evaluation report of non-coal mines from 2017 to 2018 were collected.Statistical analysis was carried out to comprehensively analyze the occupational health status of mines with different mining modes.Results The concentration of nitrogen oxide and carbono xide in non-coal mine bored by rock drill was higher than that in non-mechanical mine,and the actual contact noise intensity of drillers was reduced,but the noise intensity of mining face had little change.Conclusion Acute occupational poisoning is easy to occur in non-coal mine underground workplaces with blasting and mechanical operation under the condition of poor mechanical ventilation.
