Abstract

This analysis is based on the existence of typical engineering and geological conditions in the eastern Chinese coal mine area. In order to find the effect of aquifer drainage on land subsidence, the geology conditions of the Baodian coal mine are analyzed, and then, a 2D numerical model of strata layers was established for simulating the influence of aquifer drainage on land stability. Certain factors including aquifer and upper layer depth were taken as the influence factors in the simulation. The results indicated that the aquifer drainage can cause the land subsidence and the settlement in the industry square is not the same and changed with the distance from the shaft. In a certain distance, the settlement becomes small to lager away from the shaft and then becomes flatten.
