The Field Monitoring Experiment of the Roof Strata Movement in Coal Mining Based on DFOS [PDF]

open access: yesSensors, 2020
Mining deformation of roof strata is the main cause of methane explosion, water inrush, and roof collapse accidents amid underground coal mining. To ensure the safety of coal mining, the distributed optical fiber sensor (DFOS) technology has been applied

Movement Boundary Shape of Overburden Strata and Its Influencing Factors [PDF]

open access: yesEnergies, 2018
Strata movement boundary is not only a parameter for the prediction of overburden strata movement and deformation but also a key index of setting shafts, roadways and protective coal pillars.

Mechanical prediction method of strata movement and surface subsidence in backfill-strip mining [PDF]

open access: yesScientific Reports
Underground coal excavation has caused a series of geological disasters and environmental problems, especially coal mining subsidence. Backfill-strip mining, which combines the advantages of strip mining and backfill mining, can reduce subsidence and ...

Drilling Strata Movement Detection Experiment on Failure Law of Overlying Strata Movement [PDF]

open access: yesProceedings of the Taishan Academic Forum - Project on Mine Disaster Prevention and Control, 2014
The principle and test method of drilling strata movement detection is introduced. The failure law of stope drilling strata movement was analyzed and judged by useing the swell character of compresspoed wood when it met upon the water and moves along with surrounding rock.
