摘　　要：主要以山西煤炭运销集团金达煤业有限公司三采区大巷为研究对象,针对近距离煤层赋存特征,建立FLAC3D数值模型,经过模拟对大巷塑形破坏以及应力应变情况,确定了金达煤业三采区三条大巷的初始支护技术方案。Taking Shanxi Coal Transportation and Marketing Group Jinda Coal Industry Co., Ltd., as the research object, aiming at the characteristics of coal seam occurrence in close distance, the FLAC3 D numerical model is established to analyze the shape failure, stress and strain of the roadway. The initial support technology scheme of three main roadways in the third mining area of Jinda Coal Industry is obtained.
