A preliminary study on self calcining technique of coal gangue bricks to control chrome residues is conducted through calcining tests .

文章指出只有充分了解酸雨对高碱灰渣-煤矸石砖的淋溶特性，从而可以进一步确定高碱灰渣-煤矸石砖在使用过程中的安全性能。

The paper analysis the acid resistant of coal shale brick with high alkali ash in acid rain , and know about its security in use .

结果表明，在自养煤矸石砖的焙烧过程中，其中炭和自身热量能将铬渣中六价铬还原成（三价铬）。

The results show that charcoal and heat within the coal gangue bricks can make Cr (ⅵ) in chrome residues reduce to Cr (ⅲ) during their calcining .

本文采用自养煤矸石砖焙烧技术对铬渣进行无害化治理，对不同铬渣掺量的铬渣-煤矸石砖，进行铬的浸出毒性分析。

We adopt technique of coal gangue brick to dispose chromium residue and the leached Cr concentration and phase in sintered bricks with five various weight ratios of chromium residue to coal gangue .

结论：提出了用煤矸石生产内燃砖的合理化建议，可有效的降低煤矸石砖辐射水平，使之符合国家建材标准。

Conclusion : Make a suggestion for reduce the radiation levels of brick produce containing gangue for which accord with the national standard for building materials .
