To explore new pathways for utilization of copper tailings and mine waste rocks, these two materials were selected as raw materials to prepare sintered permeable brick. X-ray diffraction (XRD) and X-ray fluorescence spectrometry (XRF) techniques were employed to analyze mineral phase structure and chemical composition of tailings and waste rocks. Sintering mechanism was then analyzed. Compression molding method, with waste rocks as aggregates, was chosen to prepare sintered permeable bricks with a high content of tailings. An in-depth exploration was conducted on the effects of four factors, namely firing temperature, holding time, particle size of waste rocks, and content of tailings, on comprehensive performance of the brick. Ideal combination of the factors required further enhancement of mechanical strength while ensuring permeability performance of the brick, achieving a balance between strength and permeability of the brick. Research results indicated that the optimal process parameters were a firing temperature of 1 180 ℃, a holding time of 80 min, a particle size of waste rocks ranging from 2.00 to 3.35 mm (6~10 mesh), and a tailings content of 60%. Permeable brick prepared under this process exhibited a flexural strength of 4.23 MPa and a permeability coefficient of 10.1×10⁻² cm/s, both of which complied with requirements of the national standard GB/T 25993—2023 "permeable paving bricks and permeable paving flags".

为探索铜尾矿与矿山废石资源化利用新路径，本研究以铜尾矿、矿山废石为原料制备烧结透水砖。采用X射线衍射（XRD）、X射线荧光光谱法（XRF）分析了尾矿和废石的物相结构及化学组成，并对烧结机理进行了分析。实验选择模压成型法，以废石为骨料，制备了高尾矿掺量的烧结透水砖，探究了烧制温度、保温时间、废石粒径及尾矿掺量对透水砖综合性能的影响，旨在确保砖体透水性能的同时，进一步提高其力学强度，实现砖体强度与透水性能的平衡。研究结果表明：在烧成温度为1 180 ℃、保温时间为80 min、废石粒径为2.00~3.35 mm（6~10目）、尾矿掺量为50%的最佳工艺条件下，制备的透水砖抗折强度为4.23 MPa，透水系数为10.1×10⁻² cm/s，均能达到国家标准《透水路面砖和透水路面板》（GB/T 25993—2023）的要求。
