摘　　要：针对大倾角薄煤层综采工作面煤矸伤人、空间有限而难布置挡矸装置的问题,设计了架间挡矸、机道挡矸和架前挡矸3种挡矸装置。经过在贵州某煤矿应用的实践证明,该液压支架的挡矸装置安全可靠、适应性强。In high dip and thin seam working face, workers are easily hurt by fallen coal blocks and flying gangues; meanwhile, flying gangue prevention devices are not easily installed because of limited working space. This paper explains design and application of three kinds of flying gangue prevention devices： one installed between hydraulic supports, one installed at front part of hydraulic support and one installed on AFC. These three kinds of flying gangue prevention devices have been applied to some coal mine in Guizhou province and proved to be with high safety, reliability and adaptability.
