Overlying Strata Dynamic Movement Law and Prediction Method Caused by Longwall Coal-Mining: A Case Study

The surface subsidence caused by underground mining is a spatiotemporal process. impact of on structures (houses, highways, railways, dikes, etc.) and in rock strata (shafts, roadways, chambers, dynamic It necessary to study the movement law overlying process working face predict extent aforementioned structures. provides reference for pre-reinforcement post-mining treatment. This paper studies variation based survey line above Peigou Coal Mine. numerical simulation model established with different depths, fitting function determined. Finally, velocity prediction major section Mine established. accuracy this demonstrated contrasting curves basin model. In paper, method predicting strike are established, which an important theoretical protection strata.
