The invention discloses a brick making process of a porous brick, wherein the process comprises the following steps: S1, weighing raw materials: coal gangue, waste slag and riverway sludge in a weightratio of (22%-28%):(62%-68%):(8%-12%); and S2, raw material treatment: 1) coal gangue crushing: carrying out preliminary crushing and screening on coal gangue by using a coal gangue crusher, re-crushing larger coal gangue particles to obtain coal gangue particles with required sizes, and crushing to obtain two kinds of coal gangue with different particle diameters, namely small-particle coal gangue with the diameter of less than 0.5 mm, and the other kind of smaller-particle coal gangue with the diameter larger than 0.5 mm and smaller than 1.5 mm, wherein the ratio of the small-particle coalgangue to the smaller-particle coal gangue is (65%-70%): (30%-35%) The process has the advantages that the porous brick is produced by taking the coal gangue, the waste slag and the riverway sludge asraw materials, so that the porous brick has the advantages of changing wastes into valuables and recycling the wastes, and meanwhile, the porous brick has the advantages of high strength and strong frost resistance.
本发明公开了一种多孔砖的制砖工艺，包括以下步骤：S1，原料称重：煤矸石、废矿渣、河道淤泥，三种原料的称重比为22％‑28％：62％‑68％：8％‑12％。S2，原料处理：1)煤矸石粉碎：利用煤矸石粉碎机对煤矸石进行初步破碎、筛分、再对较大煤矸石颗粒重新粉碎，以获得所需尺寸的煤矸石颗粒，粉碎后获得两种颗粒直径大小不一的煤矸石，一种为直径小于0.5mm的小颗粒煤矸石，另一种为直径大于0.5mm且小于1.5mm的较小颗粒煤矸石，且小颗粒煤矸石与较小颗粒煤矸石的比例为65％‑70％：30％‑35％。优点在于：以煤矸石、废矿渣、河道淤泥为原料生产多孔砖，具有变废为宝、废物再利用的优点，同时该多孔砖本身具有强度大、抗冻性强的优点。
