粉尘采样标准在井下工作场所中的应用

Application of Dust Sampling Standard in Underground Mining

目的探讨定点采样和个体采样两种采样方法在非煤矿山井下工作场所中的应用,针对不同岗位选择适合的采样方法,同时对采样方法进行改进,以提高工作效率。方法采用不同采样方法对不同岗位接触的粉尘浓度进行检测,比较不同采样方法所得的结果。结果定点采样与个体采样结果之间的差异性较为明显,个体长时间采样与非标方法采样的结果有一定的差别,但差别不大。结论凿岩岗位、人工装矿岗位可采用定点采样作为检测手段;针对机械装矿和机械运输岗位应优先采用个体采样。

Objective To explore the application of two sampling methods on underground mining,to improve the efficiency of the work by selecting and improving sampling method in different positions. Methods Different sampling methods were used to detect the concentration of dust in different positions,comparing the results of detection. Results It was significant difference between the fixed sampling and individual sampling method obviously. There was a slightly difference between the results of the individual long time sampling and the non- standard method. Conclusion Fixed sampling methods can be used in the drilling and artificial loading position. The individual sampling can be the initial method in mechanical loading and transport position.
