摘要
采用数值方法——SAP-5有限元程序和煤炭科学研究总院北京开采研究所开发的GMEAP程序,通过微型计算机完成了单一煤层和两煤层多阶段开采岩体空间应力分布的初步研究,阐明了单一工作面及多工作面开采时,岩体应力特别是高应力区的应力分布特征,为科学地选择巷道布置、开采顺序和工作面位置以及岩层控制与支护的优化选择提供了可靠依据。
The numeric analysis, namely, SAP-5 finite element program, and GMEAP program developed by the Beijing Research Institute of Coal Mining and the mini-computer were applied in analysis of stress distribution characteristics of rock-body,especially high stress area,which provides a reliable criterion for scientific selection of entry layout and mining sequence and face position and optimal selection of roof control and supports.
