介绍了湿式旋流除尘器在掘进工作面混合式通风方式下的除尘技术,以及压入风量与抽出风量、压入风筒口与抽出风筒口距迎头的距离等参数配比试验,分析得出较合理的抽、压风筒口位置和风量。在古书院矿92211掘进工作面的试验结果表明:长压短抽通风除尘能达到较好的除尘效果。
The paper introduces the dust removal technology of wet cyclone under the mixed ventilation mode in the driving face, as well as the parameter matching test such as the distance between the forced air volume and the extracted air volume, the distance between the pressed air tube opening and the drawn air tube opening, Reasonable pumping, pressure duct position and air volume. The test results of 92211 heading face in Gushuyuan Mine indicate that the short-time ventilation and dust removal can achieve better dust removal effect.
