我省煤矿区一些矸子山或矸子道,有大量碳质页岩的资源。分未燃段和自燃段两种情况;未燃段碳质页岩如腐植酸含量高的,可试制腐植酸铵肥料;自燃段因长期风化与自燃,表层出现嫩黄、白色结核、结壳体和黑褐、黄褐色碳质页岩的碎粒、细粉。化验含有益肥分,如氮、钾、硅酸、腐植酸,以及其他微量营养元素;可直接作肥料使用。经几年田间和盆钵试验结果证明,对水稻、玉米、高粱等作物一般增产10～20%。此外,在自燃段的碳质页岩碎块、细粒中,尚含少量煤焦油、烃、酚类化合物,如经筛选、和农肥堆腐处理,并施用法得当,尚不至为害作物。
Some coal mines in our province or gangue gangue Road, a large number of carbonaceous shale resources. Unburned section and spontaneous combustion section two cases; unburned carbonaceous shale, such as humic acid content is high, the trial can be made of humic acid ammonium fertilizer; spontaneous combustion section due to long-term weathering and spontaneous combustion, the surface appears bright yellow, white tuberculosis, crust And dark brown, yellow-brown carbonaceous shale fragments, fine powder. Test contains beneficial fat points, such as nitrogen, potassium, silicic acid, humic acid, and other micronutrients; can be used directly as fertilizer. After several years of field and pot test results show that the general increase of 10-20% of rice, corn, sorghum and other crops. In addition, carbonaceous shale fragments and fine particles in the spontaneous combustion section contain a small amount of coal tar, hydrocarbons and phenolic compounds, which are not harmful to crops even after being screened and heap compost treated properly.
