| Abstract: | This paper takes the iron ore of Hebei province as research object, to analyse the relationship of the scope of gob and the law of mine losting stability and caying, aaplying the theory of elasto - plasticity to comfirm the height and shape of caving arch. As a result,the model of disposing gob and caving arch was built, which has important insight for the problem of disposing gob of underground mines. |
