武甲煤矿3101综采工作面高压喷雾降尘技术

Study on Dust Reduction Technology of 3101 Fully-mechanized Face in Wujia Coal Mine

武甲煤矿3101综采工作面在回采过程中粉尘浓度较大,工人的作业环境较为恶劣。文章采用现场实测的手段对工作面粉尘浓度的分布规律进行了分析,在此基础上提出了高压喷雾降尘技术。现场监测结果表明,该技术措施可有效降低粉尘浓度,满足矿井的正常安全生产。

The dust concentration of 3101 fully-mechanized coal face in Wujia coal mine is high and the working environment of workers is bad.In this paper,the distribution law of dust concentration in working flour was investigated by means of field measurement,and analyzed and summarized.On this basis,the high pressure spray dust reduction technology was put forward to comprehensively control the phenomenon of large dust in working flour.The engineering monitoring results show that the technical measures can effectively reduce the dust concentration and meet the normal safety production of the mine.
