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

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