煤矸石是煤炭開采及加工過程中排出的主要固體廢棄物,其組成為多種巖石的混合物。煤矸石的生產(chǎn)與煤炭產(chǎn)量分布具有密切聯(lián)系,中國(guó)的煤矸石產(chǎn)生量相當(dāng)于煤炭產(chǎn)量的10%～15%,2007年中國(guó)共生產(chǎn)原煤25.2億噸,同期煤矸石產(chǎn)量約為3億噸,

The montmorillonite content was as high as 42% for the coal gangue in Inner Mongolia Dayan Coal Co., so it was difficult to manufacture brick with this coal gangue. The production technology was reconstructed in order to resolve these difficulties. The reconstruction included materials mixing, improving raw materials fineness, extending ageing period, reducing forming resistance,increasing extrusion stress, low temperature drying and long period firing, etc. After the reconstruction, the production ability and qualified products were also improved.
