| 摘 要： | 栾川石煤是河南省境内一种比较特殊的煤种，主要分布于栾川群煤窑沟组上段，一般含石煤层2层，个别地段为3层或4层。可采石煤为第一层，厚度1．40～13．10m，一般为4-6m，分布面积大，层位稳定，连续性较好；原煤发热量4．08~12．41MJ／kg，平均7．26MJ／kg，灰分产率58．08％～82．09％，全硫平均含量1．72％，为中硫、高灰分、低发热量的劣质煤。栾川含石煤地层及煤层的分布与黄背岭一石宝沟背斜关系密切，呈环带状分布于背斜四周，变辉长岩与石煤的出露形影相依，为找矿标志层。

| Abstract: | The Luanchuan stone-like coal is a very special coal in the Henan Province. It is mainly hosted in the Upper Member, Meiyaogou Formation, Luanchuan Group. The member generally contains 2 stone-like coals, exceptionally 3 or 4 layers, the mineable is the first layer, 1.40-13.10m thick, generally 4-6m, distributes extensively and stable with better continuity. Raw coal calorific value is 4.08-12.41 MJ/kg, average 7,26 MJ/kg; ash content 58.08-82.09%; average total sulfur content is 1.72%, is a medium sulfur, high ash and low calorific value inferior coal. The distribution of stone-like coal-bearing strata has close relation with Huangbeiling- Shibaogou anticline and girdle round it, the outcropping of stone-like coal never leave each other with metagabbro, thus a marker of stone-like coal looking. |
