摘　　要：开滦唐山矿主采的5、8、9、12-1等煤层涵盖薄煤层、中厚煤层、厚煤层及巨厚煤层,煤层厚度的变化影响采掘部署、回采计划,同时还会增加巷道掘进率、降低煤炭采出率,所以研究煤层的厚度变化规律对合理利用煤炭资源具有积极的意义,本文通过对唐山矿主采煤层的煤层特征进行了分析,并对煤层特征变化以及其与唐山矿构造的关系进行分析。The coal seams of 5,8,9 and 12-1 of Tangshan Coalmine in Kailuan Group are covered with thin coal seams,medium thick coal seams,thick coal seams and huge thick coal seams,the change of coal seam thickness will affect the mining deployment,recovery plan,at the same time also will increase the rate of roadway drivage,to reduce the coal recovery rate,so it is of positive significance to rational utilization of coal resources to study the regularity of the thickness variation of coal seam. This article analyzed the characteristics of coal seam and the characteristic changes of coal seam and its relationship with Tangshan Coalmine geological structure.
