【摘要】：为有效预防煤矿粉尘职业危害,以煤矿粉尘特别是呼吸性粉尘浓度检测技术为研究对象,探讨了呼吸性粉尘颗粒物国内外分离技术和标准、分析了目前环境总粉尘浓度连续监测技术和个体呼吸性粉尘浓度监测技术,针对国内外环境呼吸性粉尘浓度连续监测技术方面尚处空白的现状,提出了开展环境呼吸性粉尘在线连续监测及个体监测技术研究的基本思路,阐述了煤矿粉尘职业危害监测预警技术的发展趋势,以及构建煤矿粉尘职业危害监测预警平台的架构模式。研究结果表明:满足"BMRC"分离曲线的分离器是实现呼吸性粉尘颗粒物浓度检测的前提,激光散射法、微量振荡天平法等是主要手段,只有建立起基于网络化大数据支撑的新型职业危害预警指标体系和预警模型,才能真正实现煤矿粉尘职业危害有效预测,提高监管水平。
[Abstract]:In order to prevent the occupational hazards of coal mine dust effectively, the separation technology and standard of respirable dust particulates at home and abroad are discussed, taking the detection technology of coal mine dust, especially the concentration of respiratory dust, as the research object. The continuous monitoring technology of total environmental dust concentration and individual respiratory dust concentration monitoring technology are analyzed. This paper puts forward the basic idea of the research on the on-line continuous monitoring of environmental respiratory dust and individual monitoring technology, and expounds the development trend of coal mine dust occupational hazard monitoring and warning technology. The research results show that the separator satisfying the separation curve of "BMRC" is the prerequisite for the detection of the concentration of respirable dust particles, and the laser scattering method is used. The method of micro oscillatory balance is the main means. Only by establishing a new early warning index system and early warning model based on network big data can the effective prediction of occupational hazards of coal mine dust be realized and the level of supervision be improved.
