Abstract: Abstract According to the movement and deformation of overlying strata caused by underground mining,the influence of roadway excavation retaining, underground pipeline operation and other practical problems. Negative exponential function is used to establish a subsidence prediction model within any estimated level in overlying strata, and compared with the results of numerical simulation, and with a example verification, have good consistency. Application of negative exponent method can accurately predict the movement and deformation of overlying strata, provides a reliable technical support for safe mining and mining under shallow buried Engineering.
