强化铁矿井下开采和降低成本的途径之一是采用自行式铲运机。由经互会国家工厂生产的ПД-3(8,12),ЛК-1等型号柴油设备,装备有两级净化排出废气的装置。在地下矿条件下的实际应用表明,所用的废气净化装置不能保证把内燃机废气中含有的有毒物质浓度降低到最大容许限度。已知的柴油机废气净化装置的净化效率不超过60～70％,而滤料的频繁再生及更
One of the ways to strengthen underground mining and reduce costs is to use self-propelled scraper. Equipped with two types of diesel engines, such as ПД-3 (8,12) and ЛК-1, which are produced by the factories of the countries of the Confederation, are equipped with two stages of purifying exhaust gases. The practical application under underground conditions shows that the exhaust gas purification device used can not guarantee to reduce the concentration of toxic substances contained in the exhaust gas of the internal combustion engine to a maximum allowable level. It is known that the purification efficiency of a diesel exhaust gas purifying device does not exceed 60 to 70%, and the frequent regeneration of filter media and more
