摘要

The paste backfill method is one of the world's most used techniques for backfilling nowadays. Among the many advantages of paste backfilling is early rock support ability. Another advantage is that there is no need to pump out excess water from the stopes. This paper discusses the application of the paste backfill method in different mining methods for mining different commodities. Thus, an overview is made of the influence factors on the application of the paste backfill method. Such influence parameters are the grain size of the aggregate as well as the binding agent used. For a better understanding of these influence factors, different case studies in China and Germany are presented. Details are given for a long wall coal mining operation and an open stope mining operation in China, as well as for salt mining in Germany. The boundary conditions that affect the application of this backfill method in diverse mining projects are shown; different materials and sequence or processes used in cases are further discussed. This paper aims to cover frontier research and determine the difficulties that the industry might be facing while applying paste backfilling
