在对大同云岗煤基础性质研究的基础上，基于现有配煤方案，通过添加云岗煤来替代部分瘦煤、1/3焦煤或气煤进行配煤炼焦，研究了煤的细度和配比等对焦炭冷、热态强度和反应性等的影响。结果表明：云岗煤细度增加，焦炭的冷热态强度均有增加；云岗煤替代气煤，焦炭冷态强度随着配比增加先升高后减小，但热态强度下降；替代1/3焦煤及瘦煤，焦炭冷热态强度均是随着配入量的增加而减小。在配煤时增加肥煤的配入量，配入≯3%的云岗煤可以保证焦炭的质量。多用云岗煤，将有利于降低焦炭硫分和灰分，扩大炼焦煤资源，降低配煤成本。

Based on the elemental and proximate analysis results of Datong Yungang coal and present coal blending scheme, the coking tests for blending with Yungang coal instead of a part of lean coal, 1/3 coking coal and gas coal were carried out. The influences of the coal fineness and proportioning on the cold-status strength, hot-status strength and reactivity of coke were investigated. The main conclusions are as follows:The cold-status strength and hot-status strength increased with the increase of the fineness of Yungang coal;With Yungang Coal instead of gas coal, the cold-status strength first increased and then decreased while hot-status strength decreased with proportioning increase; Instead of 1/3 coking coal and lean coal, the cold-status strength and hot-status strength of coke decreased with proportioning increase of yungang coal. Increasing the mixing quantity of fat coal and not larger than 3%Yungang Coal in coal blending, the quality of coke can be guaranteed. In a word, it will be beneficial for reducing sulfur and ash content in coke, expanding the coking coal resources, reducing the cost of coal blending.
