摘　　要：以义马千秋矿冲击地压倾向性鉴定结果为依据 ,探讨了缓倾斜巨厚煤层的冲击地压的影响因素及特点 ,针对性地提出开采技术、煤体注水、卸载爆破等巨厚煤层冲击地压综合防治措施。指出冲击地压特性是由煤的物理特性、矿井开采深度、开采方法等多因素决定 ,矿井应当根据本矿的具体情况 ,采取切实可行的措施。Based on the analyzed outcome of QianQiu Mine's rock burst tendency,this paper does research on items and characters related to enormously thick coal.Then it comes up with synthesized prevention measure against outburst in enormously thick coal.It points out that the coal rockburst feature is related with many items ,such as coal's physical feature,mining depth,mining methods,etc.Each mine should take care of its practical conditions and take proper measures.
