| 摘 要： | 以石炭井一矿５＃煤层上分层回采巷道为例，对缓、倾斜煤层回采巷道的４种断面形式进行了有限元模拟分析，指出了缓、倾斜煤层和近水平煤层中，回采巷道的应力、应变分布及塑性破坏特征。提出了缓、倾斜煤层回采巷道的合理断面形状和支护方式，为工程设计和实际应用提供了科学依据。

| Abstract: | The four forms of heading cross section in gently inclined and inclined seam of the upper seam heading in Shitanjing First Mine 5# seam as an example are studied with finite element simulated analysis. It points out the different characteristics of the stress-strain distribution and plastic collapse of the heading in gently inched and inclined seam and nearly horizontal seam and puts forward the reasonable cross section form and supporting pattern.This may provide a scientific basis for engineering design and practical application. |
