Abstract: The coal column protecting the railway is also the resource waing in the coal exhaued mining area.And how to solve the problem of the contradiction of coal column waing resource and the laing exploiting of mining area feasibly in the one of the difficulties that the bankrupt coalmines ma face at present.The research of this text lies in riving to solve the recovery of the coal column protecting the Xitian line railway which is ju above the column in Niuxintai coalmine.The article proposes adopting a complexion ripe mining to exploit the coal column,and analyzes especially the feasibility of the mining method.Also the paper analyzes and discusses the impact of the column mining and of the earths surface subsidence after ripes exploited on roadbed.Finally,the article points out that it is not only essential but also feasible to recover the coal column with ripe mining method,which can take the method that it is combining the reasonable exploiting scheme in the pit with the proper maintenance action on roadbed of Xitian railway.
