【摘要】 以淮南煤田C13-1煤层不同煤体结构类型煤的118个坚固性系数(f值)测定资料为基础,分析了不同煤体结构煤的f值分布特征和统计规律,说明了煤体破坏与f值的相互关系,并提出将f值作为硬煤和构造软煤的分类指标.更多还原

【Abstract】 On the basis of 118 solidity coefficients determined （f value） of different coal body structure type coal in the coal seam C_13-1 of Huainan coal field, the paper analyses the distributive feature and statistical regularity of f value of different coal structure type coal. It shows the mutual relation of coal body breakage and f value, and proposes that f value is regarded as the classification quota of hard coal and tectonic soft coal.更多还原
