Environmental concerns over increased coal consumption are fully justified by the past history of coal use. Although improved technology has provided some safeguards, increased utilization will require mining practices, emission control technologies, and waste disposal procedures that are not yet fully integrated into the routine use of the coal energy system. The Committee on Health and Evnironmental Effects of Increased Coal Utilization identified six critical environmental issues which are of concern: coal mine worker health and safety, reclamation of arid lands from surface mining, the health effects of coal combustion products, toxic trace elements in coal combustion wastes, acid fallout, and global effects of carbon dioxide in the atmosphere. This presentation addresses the first four of these issues.
过去煤炭使用的历史充分证明了对煤炭消费增加所引发的环境问题的担忧是合理的。尽管技术进步提供了一些保障措施，但煤炭利用率的提高仍需要采矿作业、排放控制技术和废物处理程序，而这些尚未完全融入煤炭能源系统的常规使用中。煤炭利用增加对健康和环境影响委员会确定了六个令人担忧的关键环境问题：煤矿工人的健康与安全、地表采矿对干旱土地的复垦、煤炭燃烧产物对健康的影响、煤炭燃烧废物中的有毒微量元素、酸性沉降物以及大气中二氧化碳的全球影响。本报告讨论其中前四个问题。
