煤矿粉尘监测技术探讨

Discussion on Monitoring Technology of Coal Mine Dust

分析了煤矿粉尘的危害、特性和作业场所空气中呼吸性煤尘接触浓度标准,介绍了煤矿粉尘监测技术的发展状况,比较了取样法与非取样法的特点,指出非取样法应为煤矿粉尘监测的主要方法,并指出非取样法中的光散射法最适用于煤矿井下。应用光散射法研制的GCG1000粉尘浓度传感器在煤矿井下的应用验证了该方法的有效性。

The paper analyzed harm and characteristics of coal mine dust and standard of contact concentration of respiratory coal dust in air of working space,introduced developing status of monitoring technology of coal mine dust,and compared characteristics of sampling method and non-sampling method.It pointed out that non-sampling method should be a main monitoring method of coal mine dust and light-dispersion method in non-sampling method is most suitable for coal mine underground.Application of GCG1000 dust concentration sensor based on light-dispersion method in coal mine underground showed availability of the method.
