摘要
利用FLAC3D数值模拟软件对整个回采过程进行模拟,计算分析出尾巷表面的位移量。通过S5-8工作面尾巷表面位移的现场观测,总结出了受采动影响尾巷围岩的变形速度、规律及采动影响范围。采用数值模拟同现场观测相结合的方式来验证S5-8尾巷支护受动压影响后,可以满足为S5-6工作面配风的要求。
The table Simulating the whole mining process by utilizing FLAC3D numerical simulation software, computational analysis of the tail roadway displacement of surface. Through the tail roadway of S5 - 8 field measurement of surface displacement, summed up the tail roadway surroundding rock deformation speed, regularity and extent of effect by mining influences. By numerical simulation and field measurement to verify the support of S5 -8 tail roadway affected by dynamic pressure, tail roadway be able to contented require- ments of air distribution for S5 -6 coal face.
