[0002] my country is rich in mineral resources. With the exploitation of mineral resources, problems such as surface subsidence and mining resource destruction have become increasingly prominent. Therefore, backfill mining has obvious advantages. However, there is currently little research on the performance, strength, and stability of the backfill body.

[0003] At present, the filling body test is mainly based on indoor tests, the most common of which are uniaxial and triaxial pressure tests, which study the seepage characteristics and shear strength performance of the filling body. Some scholars use consolidation instruments and expansion rate testers to study the expansion of the filling body during the consolidation process and evaluate the long-term stability and support effect of the filling body in the goaf. However, these studies are based on the fact that the indoor environment is quite different from the actual filling environment, and cannot simulate the stress state of the filling body on site.

[0004] This application is based on the actual field environment. The equipment is arranged inside the filling body. The data is transmitted to the data center through temperature sensors, seepage sensors, displacement sensors, and stress sensors, and finally transmitted to the ground. Ultimately, real-time monitoring of the stability and curing process of the filling body is completed, which is of great significance to the research on filling bodies in field environments.
