Summary:70%∼80% of the roadway is affected by mining, the most prominent problem is roadway maintenance under the influence of cross-mining. In this paper, the support of a rock backwind roadway in the east NO.4 mining area of a coal mine in huai-nan mining area is studied under the influence of mining in the lower 11-2 coal seam, The comprehensive support method of hollow grouting anchor cable anchoring and block erection is developed, and has carried on the successful application in the practice.
