我国地下金属矿山全尾砂胶结充填技术述评

全尾砂胶结充填技术将选厂全尾砂充填到井下,可减少甚至取消尾砂在地表存放用地,解决因尾砂堆存带来的环境污染,节约尾矿库的建设和管理维护费用,同时又可满足充填采矿的要求.近十多年来,全尾砂充填技术的研究取得了较大的进展.本文结合实例较详尽的介绍了全尾砂胶结充填技术的应用研究现状,并就其发展方向进行了探讨.

COMMENTS ON CEMENTED FILLING WITH UNCLASSIFIED TAILINGS IN CHINA'S UNDERGROUND METALS MINES

The unclassified tailings from the mill are filled into underground by use of the techniques of cemented filling with unclassified tailings. This doing can reduce or even eliminate the occupied land which tailings were stored on the surface, avoid the environ-mental pollution caused by tailings storage, save the constructing and maintaining costs of tailing pond, and meet the requirements for mining with filling. In the past more than 10 years, There is a greater progress in the study on the techniques of cemented filling with unclassified tailings. The authors use the specific examples to make a more detail introduc-tion to the present situation of the study on the application of cemented filling with unclas-sified tailings, and an approach to its future trend.
