我国目前由于产煤而生成的煤矸石堆存量已达４０亿ｔ,并以每年１．５亿ｔ的速度递增,这不仅占用大量土地,还造成严重的环境污染。２０世纪６０年代,我国已试制成功煤矸石砖。“八五”期间,引进欧洲煤矸石制砖技术,在双鸭山建成年产６０００万块全煤矸石空心砖生产线。这项技术 At present, the stock of coal gangue generated in China due to coal production has reached 4 billion tons and has been increasing at a rate of 150 million tons per year. This not only consumes a large amount of land but also causes serious environmental pollution. In the 1960s, China successfully trialled coal gangue brick. During the “Eighth Five-Year Plan” period, the introduction of European coal gangue brick technology, built in Shuangyashan with an annual output of 60 million whole coal gangue hollow brick production line. This technique
