摘要
Abstract
In view of mechanical characteristics of strip pillar, roof subsidence of strip pillar that affected by mining and pillar width, was analyzed. Results showed that roof subsidence and pillar width have an inverse relationship. The smaller size of coal pillar is, the greater roof subsidence will be, vice versa. On this basis, prediction of surface deformation was analyzed by using probability integral method , so that a reasonable plan of deep strip mining was determined.关键词
