1、煤質資料按：a礦入洗比例35%，b礦65%設計。按：a礦入洗比例55%，b礦入洗比例45%設計。1 煤的化學性質:（1） 灰分分析:a礦4#煤灰分為27.55%，b煤灰分為31.41%，均屬于中灰煤，一般生產(chǎn)8-10級精煤。（2）有害物質和元素分析:硫分分析: a礦4#煤硫分平均為0.4%,為特低硫煤，b煤硫分平均為1%,按比例35：65混合入洗，原煤為特低硫煤。按中國煤炭分類標準（gb5751-86）劃分，一精煤揮發(fā)分（900vdaf%）和粘結指數(shù)（gr。i。）為主要分類指標，角質層厚度（ymm）、奧亞膨脹度（b%）為輔助指標進行。選煤廠入選的煤層都屬主焦煤。表2-1 a礦篩分試驗報告表粒度
