n.石炭

Three types of coal were discovered in this are, namely the coking and anthracites and semi anthracites. 在這個地區(qū)找到了三種煤炭，即焦炭，無煙煤和半煙煤。

No.6 and 7 coal seams are anthracites characterized by low ash,super-low sulf... 近南北向和北北東向的斷裂為正斷層,對馬頭嶺賦煤向斜構造造成切割破壞,使西翼淺部煤層未能保存。

Although the Raman peaks of bitumen are stronger and sharper than the anthracites, their Raman spectroscopic characteristics are very similar. 固體瀝青的拉曼光譜峰形與無煙煤相似，不過其峰的半高寬比較窄，二級峰也比無煙煤要明顯得多。

From the combustion characteristics point of view, bituminous coals are the best, lean coals and anthracites are the second, stone coals are the worst. 結果表明：在熱重試驗條件下，煙煤的燃燒性能最好，貧煤和無煙煤次之，石煤最差。

Using black liquor of paper pulp plant as catalyst,the steam gasification of high metamorphosed anthracites was investi- gated by isothermal thermo-gravimetric analysis under ambient pressure. 以紙漿黑液為催化劑,用熱天平的等溫法研究高變質無煙煤常壓純水蒸氣催化氣化反應。
