Strong Structure Formation of Ceramic Composites Based on Coal Mining Overburden Rocks

Journal of Composites Science, 2023
Currently, the amount of man-made waste worldwide is steadily increasing. It is, therefore, necessary to constantly look for effective ways of utilization and recycling. It is also necessary to reduce the use of non-renewable resources and reduce the impact on the environment.

Investigation of structures in tunnel overburdens by means of muon radiography

Journal of Instrumentation, 2022
Abstract Cosmic ray muon radiography is a new imaging technique that is being used to investigate the density structure of large objects and the shallow crust. For example, it has been used to investigate magma conduits of active volcanoes, cavities above tunnels and hidden chambers inside pyramids, and has proven to be effective

Study on Characteristics of Overburden Strata Structure above Abandoned Gob of Shallow Seams—A Case Study

Energies, 2022
To understand the change in overburden structure after coal seam group mining, we investigated the overburden characteristics and bearing capacity of abandoned coal mines in a coal seam group. We provide a theoretical basis for the construction and utilization of a coal mining subsidence area under a complex geological environment. This paper takes the
