The Strata Movement Regularity and Parameter Simulation Analysis in Multiple Seams Repeated Mining

Abstract:

The vast majority of China's coal mine was located in mountains and multi-seam mining and seam slice mining were the most common type. With the depth of our mining coal seam increased, it is important to research the regularity that the repeated mining affected the surface subsidence. The current paper used the measured data of Jia Lequan and simulated the surface deformation after removed the impact of the mountainous terrain to compare the trend and mechanism of the surface movement and parameters in repeated mining. Proposed the surface movement and deformation under the multi-seam repeated mining, and laid the foundation for the future research in repeated mining.
