摘　　要：在瑞能煤业有限责任公司采空区留下的相临的2条块区段煤柱中间试掘运输巷和回风巷(简称区段煤柱中巷)。由于2条巷道均出现压力大,造成巷道难以支护,影响正常掘进。以该矿区段煤柱中巷支护为工程背景,采用三维有限差分法数值计算软件(FLAC3D)分析巷道掘出后围岩的应力场和位移场并对不同支护方式巷道的变形破坏机理进行对比性模拟,并根据模拟实验结果制定支护方案,为区段煤柱中巷支护方案的优化确定提供科学依据。Try to excavate two roadways on both sides of sectional coal pillar in mined-out area of long- wall in the Ruineng coal mine. Due to pressure of two roadways, resulting in difficult to support in road- way, affect normal driving. According to the technology of supporting roadway in the middle of the section coal pillar in mined-out area of long-wall in the Ruineng coal mine, numerical simulation with FLAC^3D on stress, displacement fields and destroy in roadway under different supporting, and carried out the necessary analysis on the results of simulation experiments. The results are of reference for on-site decision- making roadway program.
