Abstract: Backfilling mining technology is an important support technology for the green and high-quality development of metal mines. The branch research direction of monitoring of backfilling solidification process in the field of filling was proposed by the research group,aiming to break the bottleneck problem of in-situ strength monitoring and characterization of metal mine stope backfilling fields. Combined with the relevant research progress of the group,the technical ideas of the theory and application of metal mine backfilling and curing research are summarized. The research status of the theory and application of multifield performance monitoring of metal mine backfilling and curing process is systematically expounded from the aspects of multi-field performance monitoring technology, multi-field performance evolution law, multi-field performance mechanism, multi-field performance correlation mechanism,backfill strength and multi-field performance characterization model,numerical simulation of backfilling and curing process,and engineering application. On the basis of the above analysis,the future development direction is foreseen from three levels:theory,technology and device,and the subsequent focus needs to be tackled as follows:real stope field-wide numerical simulation,backfill safety early warning technology based on curing process monitoring, development of wireless,accurate and low-cost curing process monitoring sensors and engineering promotion application.
