Applied Sciences, 2023 Green mining plays a vital role in achieving environmentally friendly and ecologically sound mining practices. In domestic mining areas, the coal mining method is gradually transitioning from collapse mining to filling mining. Paste filling has been proven effective in controlling surface deformation, although the understanding of its underlying ...

International Journal of Mining Science and Technology, 2016 Abstract To analyze the overlying strata movement law of recovering room mining standing pillars with solid backfilling. Physical simulation experiments with sponge and wood as the backfilling simulation material were tested. The results show that: (i) The covering-rock mechanics of the overly strata comes from “two-arch structures + hinged girder ...

Processes, 2023 The surface subsidence caused by underground mining is a spatiotemporal process. The impact of mining on surface structures (houses, highways, railways, dikes, etc.) and structures in rock strata (shafts, roadways, chambers, etc.) is a dynamic process.

Research on Movement Monitoring and Law of Overlying Strata in Goaf Based on IMU Technology [PDF]
E3S Web of Conferences, 2023 The overlying strata of the stope can be divided into low ( immediate roof ), medium and high strata according to the degree of influence of the mine pressure behavior of the working face.

Overlying strata movement with ground penetrating radar detection in close-multiple coal seams mining [PDF]
International Journal of Distributed Sensor Networks, 2019 Longwall mining is a productive mining method that has been widely used in China, the United States, Australia, and Europe. However, due to the subsidence caused by coal mining activities, the phenomenon is complex, longwall mining brings the overburden movement issues accompany with the coal recovery.

Nonlinear Elastic Foundation Plate Model Study on Overlying Strata Movement in Working Face with Solid Backfilling Mining [PDF]
Shock and Vibration, 2021 Although solid backfilling materials are featured with obvious nonlinear stress‐strain properties, for a long time, they have been usually simplified as linear elastic materials for approximate calculation in mechanical analysis, so it is difficult to accurately reflect their deformation process.

Mining-induced movement properties and fissure time-space evolution law in overlying strata
International Journal of Mining Science and Technology, 2012 Abstract Mining-induced fracture zone will be produced in the overlying strata after the coal was mined. In this article, the mining-induced deformation of overlying strata and the time-space evolution law of fissure were studied by the methods of physical simulation and field measurement.

Theoretical framework and reliability verification of the loaded three-zone structural model in coal mine overburden strata [PDF]
Scientific ReportsThe fundamental stresses that determine rock burst in coal mine workings are primarily gravitational stress and tectonic stress, with the inducing force mainly coming from the stress generated by the structural movement of the overlying strata in the ...
