The present invention discloses a coal gangue sintered brick. The coal gangue sintered brick consists of the following components in proportion by weight: 70-75% of coal gangue; 10-15% of emulsion waste oil; 2-5% of silica fume or cement; and 10-13% of water. The present invention further discloses a method for preparing the coal gangue sintered brick. The method comprises the following steps of: preliminary crushing, smashing, screening, mixing, stirring, aging, secondarily stirring, carrying out vacuum extruding, slitting, carrying out brick-body molding, drying, sintering, and cooling. According to the coal gangue sintered brick and the preparation method therefor disclosed by the invention, the coal gangue and the emulsion waste oil are used as main raw materials for brick preparation, so that not only can cultivated lands and land resources be saved, but also damages to vegetation and river environment can be avoided; and produced bricks have good plasticity, better bearing capability, good water permeability, andare energy-saving and environmentally-friendly.
