In order to determine surface deformation after mining in 13 - 0211 and 14 - 0301 working face,《 calculation system of underground mining subsidence 》 software was adopted to calculate and analyze surface deformation after single mining 13 - 0211 and 14 - 0301 working face respectively and both mining these two working faces. The results showed that surface deformation after mining both adjacent working faces was less than accumulated sum of deformation after mining these two working faces respectively, which showed that countervailing processes existed in surface deformation after mining two working faces.
