An Investigation on Mining Recovery, Processing Ratio and Utilization ratio of Coal Mines in China
摘要
Abstract
The paper introduces results of a comprehensive investigation on coal mines all over Chi-na.Statistical data concerning mining recovery , processing recovery , utilization ratio were ana-lyzed.total output of raw coal was about 2493959.4 kt.Large scale coal mines were accounting for 8 .00%in all in China and production capacity was accounting for 60 .71%.Ming recovery was 83 .29%, the processing ratio of raw ore was 41 .83%, if the lignite was processed the processing ratio of raw ore was 50 .42%;the utilization ratio of associated minerals was 30 .21%.关键词
