摘要
矿产资源开发过程中产生的废石、尾砂和冶炼渣,等占我国工业固体废料排放量的85%左右。大量矿山固体废料堆放地表,易造成严重污染,诱发泥石流、尾矿溃坝事故。固体废料充填工艺是解决矿山废尾排放的最有效途径。本文介绍了低浓度分级尾砂充填、全尾砂高浓度充填、膏体似膏体充填、块石胶结充填工艺的研究与应用现状,并分析了矿山废石全尾砂充填技术的研究与发展方向。
The waste rock, railings and smelter slag in the process of the exploitation of mineral resources accounted the industrial solid wastes for about 85 % in China based on traditional mining pattern. A large number of the solid waste pilled up on the ground in mine can cause serious pollutions, and may induce mudflows and railings dam-break accidents. Undoubtedly, the solid waste backfill is the most effective way to solve the discharge of mine waste. In this paper, the present situation of research and application of several filling technology are described with regard to low-density classified tailings backfill, high-density total tailings backfill, paste and like paste backfill, as well as rock cemented backfill. Furthermore, the directions of R＆D on backfill with waste rock and total railings in underground mine were analyzed.
