萍乡风化煤资源丰富,据初步勘查储量在2000万t以上。分布在高坑、安源、青山、麻山、桐木、赤山一带近百余处,埋藏浅,容易开采。不少风化煤(也叫“露头煤”)由于长期暴露在空气中,风吹雨淋,或经煤层地下水中溶解氧的作用,形成了再生腐植酸。腐植酸含量,一般品位在30～40％, Pingxiang weathering coal is rich in resources, according to preliminary exploration reserves of 20 million t or more. Distributed in the high pit, Anyuan, Castle Peak, Ma Hill, Paulownia, Chishan near the area more than a hundred, buried shallow, easy to mine. Many weathered coal (also called “outcrop coal”) forms a regenerated humic acid due to long-term exposure to the air, wind and rain, or dissolved oxygen in the groundwater of coal seams. Humic acid content, the general grade of 30 to 40%
