|
|
Abstract According to the complex mining and geological conditions of deep excavation in Xinji mine，similarity model test is carried out for strata movement and surface subsidence due to coal extraction in No.3 mining district. Based on the analysis of repetitive mining with thick soil layers and deep coal seam，the special phenomena are put forward and the basic features of strata movement and the related parameters of mining subsidence are obtained. Also，the results are of tutorial impact for practical mining and governing of subsidence hazards.
