摘　　要：针对纳林河二号矿井选煤厂原煤准备车间处理能力不足,筛分效率低以及块末煤洗选系统不平衡的问题,提出了改造原煤分级筛和配筛刮板等改造方案,分析了增加+100 mm特大块原煤转载胶带(方案A)与更换原煤分级筛(方案B)两种改造方案的投资,得出方案A较优,从而为其他选煤厂的原煤分级筛改造提供借鉴。In response to the problems of insufficient processing capacity,low screening efficiency,and unbalanced block coal washing system in the raw coal preparation workshop of Nalinhe No.2 Mine Coal Preparation Plant,it is proposed to transform the raw coal grading screen and the screening scraper,respectively,by adding+100mm ultra large block raw coal transfer belt(Plan A)and replacing the raw coal grading screen(Plan B).Through investment analysis,it is concluded that Plan A is better,providing reference for the transformation of raw coal grading screens in other coal preparation plants.
