特殊覆岩空间结构下的支承压力分布研究

Study on the distribution of abutment pressure under special overlying strata spatial structure

本文对红阳三矿西二采区1206工作面掘进期间遇到的特殊覆岩空间结构进行分析,通过对各种剖面结构下的支承压力情况进行分析,做出应力曲线,判断出危险区。

This paper analyzed the special strata spatial structure in 1206 working face of the west two mining area in Hongyang three mine during tunneling,through the analysis of abutment pressure of various kinds profile structure,make the stress curve,judge the danger zone.
