矿山道路的特点是坡道长、坡度大、弯道多、路面凹凸不平和粉尘污染严重。因此，长期行驶于矿山道路上的载重汽车，运行环境是相当恶劣的，尤其是减震能力差的矿山机械更为严重。为此，对矿用汽车、铲运机等矿山机械所使用的空气滤清器性能也就提出了特殊的要求。我们知道，对 Mine roads are characterized by long ramp, large slope, curved corners, uneven road surface and serious dust pollution. Therefore, long-term driving in the mine road truck, the operating environment is quite poor, especially the mining machinery with poor damping ability even worse. To this end, mining vehicles, scrapers and other mining machinery used by the performance of the air filter also put forward special requirements. We know, right
