Abstract: The partial mining subsidence is a technical method widely used in the mining under buildings. How to calculate the subsidence caused by the partial mining is the key to use this method. By using the numerical calculation method, the main factors affecting the subsidence caused by the partial mining were analyzed, which include the recovery ratio of the partial mining, the width of the mined strip, the thickness and the depth of the mined seam, the conditions of the overburden. The relationship between the partial mining subsidence and the main factors was given according to the calculated results, which provides a theory basis for design and application of the partial mining.
