Research on Field Measurement of Earth Surface Dynamic Deformation of Shallow Coal Seam

High-intensity mining of shallow coal seam is easy to induce serious mining subsidence disaster. In order to analyze the characteristics of earth surface subsidence after shallow coal seam mining, to prevent mining subsidence disaster, the earth surface movement observation station is arranged on the 9102 working face of Maying coal mine. The dynamic deformation monitoring is carried out according to the closed measurement route by using the detection method, and the earth surface movement dynamic characteristics of shallow coal seam is researched.
