煤矿井下粉尘污染定点监测与结果评估研究

Research on fixed-point monitoring and result evaluation of dust pollution in coal mines underground

作为煤矿生产中的必然产物,粉尘的来源广泛,这些粉尘不仅具有复杂的物理化学性质,其浓度和分布特征也受多种因素影响。本文旨在通过定点采样及检测分析的方法,全面、系统地研究煤矿井下粉尘的特性和危害,通过采样点的选择与布置、采样仪器的准备与校准以及采样过程的具体操作,以保障数据的准确性。同时根据检测结果,揭示粉尘的浓度、粒径分布、化学成分及爆炸性等特征,以期为针对性的防尘措施的制定提供有效依据。

As an inevitable product in coal mine production,dust has a wide range of sources.These dust not only have complex physical and chemical properties,but their concentration and distribution characteristics are also affected by various factors.This article aims to comprehensively and systematically study the characteristics and hazards of coal mine underground dust through fixed-point sampling and detection analysis methods.By selecting and arranging sampling points,preparing and calibrating sampling instruments,and performing specific operations during the sampling process,the accuracy of data is ensured.At the same time,based on the detection results,the concentration,particle size distribution,chemical composition,and explosiveness of dust are revealed,in order to provide effective basis for the development of targeted dust prevention measures.
