摘　　要：研究了以平顶山八矿瘦煤为主要原料制备型焦的配煤方案,实验时首先对所用的各原料煤破碎、筛分,再进行工业分析,然后根据配煤原理制定配煤方案。煤混配后在成型机上成型,得到的型块通过冷压成型工艺制成型焦,随后对制得的型焦测其抗压强度和对CO2的化学反应性。结果表明：以瘦煤为主要原料制备型焦的最佳配煤方案是：90%瘦煤配入10%的肥煤。This paper discuss the means of coal blending to produce briquetting coke by using lean coal which is picked in the eighth mine in Pingdingshan. At the beginning of experiment, after all the raw material having to be crushed and screened, come to carry out proximate analysis. Second, according to the coal blending principle start to map out the way of coal blending. Third, after the briquetting coal having to be prepared by cold-pressed machine, then make the briquetting coal which have been made to be briquetting coke through cold pressing,measure the compressive strength and reactivity of briquetting coke. Finally, through complete test analysis, The experiment results showed that 90% lean coal blended with an amount of 10% fat coal could produce excellent briquetting coke.
