余吾煤业煤巷掘进工作面粉尘浓度测试方案研究

Study on test scheme of dust concentration in coal roadway driving of Yuwu Coal Industry Company

以余吾煤矿煤巷掘进工作面为例,从测点选置、采样过程和数据三个方面分析,结合矿井安全生产的有关因素,对掘进工作面呼吸性粉尘浓度进行测试,并提出了相关改进建议。

Taking the driving face in coal roadway of Yuwu Coal Industry Company as an example, this paper analyzed the three aspects of measuring point selection, sampling process and data, combined with the relevant factors of mine safety production, the respiratory dust concentration in the driving face was tested, relevant improvement suggestions were also put forward.
