摘    要:该文在现场实测、理论分析、数值模拟基础上,研究了深部矿井综放工作面沿空回采巷道矿压显现与矿压控制特点。通过对层状煤系地层巷道围岩复合结构特征的分析,提出了综放工作面回采巷道围岩岩性结构、几何结构的概念,研究了不同应力条件下围岩岩性结构巷道塑性破坏区域的分布特征及控制对策。

关 键 词:深部矿井  沿空回采巷道  矿压显现与控制

Abstract:Based on field observation,theory analysis and digital simulation,the authors present the rules of mining pressure manifestation of roadway along the mined area in deep mine sublevel caving longwall face.According to the analysis of compound strata of roadway,the authors get the surrounding rock structure and geometrical structure of roadway which is along the mined area.Finally this paper presents the control methods of surrounding rock under different stress distribution and plastic zones.
Keywords:Deep mine Roadway along the mined area Mining pressure manifestation and control
