Abstract: In order to solve the problem of over furrow mining in shallow seam with ultra thin bedrock, the paper takes the design of crossing ditch mining plan for 30108 and 30110 working face of Yanghuopan coal mine in Shenfu mining area as an example. taking 30108 and 30110 working face of Yanghuopan coal mine in Shenfu mining area crossing ditch mining design as an example, discussed the necessity and feasibility of crossing ditch mining, combined with research surrounding similar coal mine, put forward three feasible crossing ditch mining scheme. From the security, technical and economic aspects of the programme to be selected, Scheme that taking measures of covering soil in ditch,Paving flexible network in working face and Pressuring ventilation is an effective scheme of Yanghuopan coal mine, and provides a new solution for the similar mine.
