Based on broken coal mine resources and large mined out areas caused by backward mining method of small coal mine, No.2 compound mining coal seam in Xuehugou Mine was taken as engineering background. Rational specifications of roadway driving face, driving method and support mode in compound mining coal seam were analyzed, easpecially for mine laneway. FLAC3D numerical simulation technique was selected. All of these made results more rational, provided reasonable solutions for actual construction and the effect was remarkable.
