摘　　要：针对井下条带煤柱受力特点,分析了不同采留宽尺寸对条带煤柱顶板下沉的影响,研究表明:条带煤柱的顶板下沉量与留设的煤柱尺寸成反比,留设的煤柱尺寸越小,则顶板下沉量越大;反之,则顶板下沉量越小;在此基础上,运用概率积分法对其引起的地表变形进行预计对比分析,从而综合确定了合理的深部条带开采方案。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.
