采用自编ＣＲＡＰ程序及有限元分析方法处理了大量现场观测数据，分析了煤层群盘区底板巷道地压分布规律。进而确定底板巷道的合理空间位置、支护参数及断面形状，对底板巷道的合理设计和安全生产具有实际意义。
A large number of on-site observation data were processed by self-made CRAP program and finite element analysis method, and the ground pressure distribution pattern of the bottom plate roadway in the coalbed group panel was analyzed. And then to determine the reasonable space location of back roadway, support parameters and cross-sectional shape of the bottom of the roadway reasonable design and safety production of practical significance.
