The national rule of "Coal and Gas Outburst Prevention and Control Regulations" regulates: coal-rock pillars shall not be retained in the goaf when exploiting outburst mining the protective layer. Tiefa Dalong mine' No.13 coal layer has been identified as the outburst layer, and the upper protective layer No.12 coal layer is being exploited. In order to exploit without coal-rock pillars, Tiefa Dalong mine is designed using the scheme of full driving along next goaf. Based on the tilting rock beam theory, the laneway rib deflection of stope laneway and roadside supporting resistance can be calculated, so that the supporting scheme of timber wall has been proposed and successfully resolved the problem of roadside supporting. This scheme promotes the coal recovery rate and creates the great economic benefit.
