Analysis and assessment of surface mining degree under the condition of thick alluvium

摘要：

　　The surface movement was significantly impacted by alluvium under the condition of thick alluvium.Soit contributes practical and heuristic significance to analyze the degree of mining subsidence.First, several common mining degree calculation method were sorted out.Then, the idea of the higher the reduction factor ,the lower the alluvium characteristics reflected and the thick alluvium could be defined according to the reflected degree of its characteristics as the main line, the relationship between several calculation method was given.Based on the reduction factor and the ratio of the alluvium stratum thickness and bedrock thickness, the thick alluvium was defined.
