Research Progress on the Preparation of Cementitious Filling Materials Using Solid Waste Cementitious Materials in Collaboration with Tailing
With the rapid development of China's metallurgical industry,the scale of tailing produced by mines is also increasing,the storage of tailings not only occupies farmland and damages the environment,but improper handling can also trigger disasters.In addition,after mining,in order to prevent safety accidents such as land-slides,China requires mines to be backfilled to reduce the impact of mines on the surrounding environment.My backfilling refers to the backfilling of filling materials into the underground goaf,which can control the collapse and surface settlement of the goaf,at the same time,it can also backfill solid waste such as tailing and low-qual-ity metallurgical slag into the underground goaf,thereby reducing the accumulation of solid waste on the surface and avoiding environmental pollution and geological disasters.This article summarizes the definitions and types of steel slag,slag,and industrial by-product gypsum in industrial solid waste,as well as the definition and applica-tion of ultrafine tailing,based on the research of domestic and foreign scholars,the advantages and feasibility of using solid waste cementitious materials in conjunction with tailings to prepare cementitious filling materials in terms of economy and environmental protection are obtained,and the prospects for developing a diversified solid waste cementitious system are discussed.
