College of Construction Engineering��Jilin University��Changchun 130026��China
After coal-bearing bed mining��the caving zone��fractured zone and bend zone would form in the overlaying strata�� According to the natural geographical��regional geological and hydrological geological conditions in Yingcheng coal mine��combining with overlaying strata damage theory��the height of caving fractured zone and the biggest influence depth of the building of Yingcheng coal mine are sum for 270 m��which far less than the minimum coal mining depth ( 838 m) ��therefore��the region will not produce larger uneven settlement��
