摘要/Abstract

摘要：

通过对6种不同煤化度煤的可捣固性能的研究发现，不同煤化度煤种的可捣固性能差别很大，中等煤化度的烟煤可捣固性能较好。同时以气煤和肥煤为研究对象，考察成型压强、水分含量及粒度组成对煤饼性能的影响后发现，最适宜成型压强在30MPa左右，各煤种都存在属于自己的最佳水分区间，粒度组成对煤饼性能的影响也十分显著。

Abstract:

It is discovered through the study on the stamp-able property of 6 kinds of coal with different coalification degrees that the stamp-able properties of the coals with different coalification degrees have very great differences and the anthracite with medium coalification degree has better stamp-able property. Meanwhile it is found that the most suitable stamping pressure intensity is about 30MPa after the effects of stamping pressure intensity, moisture content and grain size composition on coal cake property are investigated with gas coal and fat coal as study subjects. Each of these kinds of coal has its optimum moisture range and the grain size composition has very obvious influence on coal cake property.
