摘　　要：为揭示工作面超前支承压力分布规律,采用理论分析、数值模拟及现场实测的方法,对兖州矿区进行工作面支承压力进行了分析,得出综放与分层开采工作面超前支承压力分布变化的规律,为回采巷道超前支护长度、支护强度等提供了理论依据。In order to disclose the law of abutment pressure in the working face, this article, with the methods of theoretical analysis, numerical simulation and spot test, analyzes the laws of abutment pressure in the working face in Yanzhou mining area and gains the variational law of abutment pressure in front of the fully-mechanized sub-level and slice mining working face. The conclusion of this article provides the theoretical basis for advanced timbering length and supporting intensity in the roadway.

关 键 词：综放与分层工作面 超前支承压力 数值模拟
