【摘要】：為有效預防煤礦粉塵職業(yè)危害,以煤礦粉塵特別是呼吸性粉塵濃度檢測技術為研究對象,探討了呼吸性粉塵顆粒物國內外分離技術和標準、分析了目前環(huán)境總粉塵濃度連續(xù)監(jiān)測技術和個體呼吸性粉塵濃度監(jiān)測技術,針對國內外環(huán)境呼吸性粉塵濃度連續(xù)監(jiān)測技術方面尚處空白的現狀,提出了開展環(huán)境呼吸性粉塵在線連續(xù)監(jiān)測及個體監(jiān)測技術研究的基本思路,闡述了煤礦粉塵職業(yè)危害監(jiān)測預警技術的發(fā)展趨勢,以及構建煤礦粉塵職業(yè)危害監(jiān)測預警平臺的架構模式。研究結果表明:滿足"BMRC"分離曲線的分離器是實現呼吸性粉塵顆粒物濃度檢測的前提,激光散射法、微量振蕩天平法等是主要手段,只有建立起基于網絡化大數據支撐的新型職業(yè)危害預警指標體系和預警模型,才能真正實現煤礦粉塵職業(yè)危害有效預測,提高監(jiān)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.
