Wangzhuang Coal Mine of Shanxi Province Lu'an Chemical Group

为了解决王庄煤矿91-103巷道粉尘浓度严重超标问题,在综掘工作面应用了湿式除尘器进行降尘。结果表明:掘进机司机处总尘、呼尘平均浓度分别降低到11.1mg/m³、6.5mg/m³,工作面其他作业区域内的粉尘浓度也明显降低,总体降尘效果良好。

In order to solve the problem of serious excessive dust concentration in the 91-103 roadway of Wangzhuang Coal Mine, a wet dust collector is applied to the working face for dust reduction. The results show that the total dust and exhaled dust concentrations at the driver's location of the tunneling machine decreased to 11.1 mg/m³,6.5 mg/m³, respectively. The dust concentration in other working areas of the working face also significantly decreased, and the overall dust reduction effect is good.
