利用数值模拟技术选择巷道合理的支护参数

摘要

Based on the essence of the roadway support design at coal mines, the study adopts FLAC-3D technique to have the numeric simulation study on the bolt spray supporting design, and points out the reasonable support parameter by analyzing the stress field at the surrounding rock mass of the bolt spray supporting roadway and its displacement changes, so as to direct the roadway construction.%根据煤矿巷道支护设计的实质,结合在建巷道工程,采用FLAC-3D技术对巷道锚喷支护设计进行了数值模拟研究,通过分析锚喷支护巷道围岩体应力场和位移变形状况,提出了巷道合理的支护参数,用以指导巷道施工。
