开滦矿区强粘结性煤校核粘结指数测定的研究

Study on determining of checked coking index for strong caking coals in Kailuan coal mining field

摘要: 以开滦矿区7种强粘结性煤为研究对象,通过改变粘结指数测试过程中待测烟煤和标准无烟煤间的配比,研究了开滦煤的校核粘结指数。结果表明,当待测烟煤和标准无烟煤的配比为0.7∶5.3时,粘结指数的区分能力较好,可有效区分开滦矿区强粘结性煤的粘结能力。

Abstract: Based on seven strong coking coals sampled from Kailuan coal field,this paper investigated checked caking index of Kailuan coals by adjusting the blending ratio of bituminous coal and standard anthracite.It is achieved that there is good distinguishing ability for strong coking coal when the blending ratio of bituminous coal and standard anthracite is 0.7∶ 5.3,which provides a method for differentiating strong coking coal.
