374.F 2.6Mta炼焦煤选煤厂初步设计(CAD图纸联系本人)资料

1、煤质资料按：a矿入洗比例35%，b矿65%设计。按：a矿入洗比例55%，b矿入洗比例45%设计。1 煤的化学性质:（1） 灰分分析:a矿4#煤灰分为27.55%，b煤灰分为31.41%，均属于中灰煤，一般生产8-10级精煤。（2）有害物质和元素分析:硫分分析: a矿4#煤硫分平均为0.4%,为特低硫煤，b煤硫分平均为1%,按比例35：65混合入洗，原煤为特低硫煤。按中国煤炭分类标准（gb5751-86）划分，一精煤挥发分（900vdaf%）和粘结指数（gr。i。）为主要分类指标，角质层厚度（ymm）、奥亚膨胀度（b%）为辅助指标进行。选煤厂入选的煤层都属主焦煤。表2-1 a矿筛分试验报告表粒度
