深井回采巷道围岩稳定性分类及其控制技术

Stability Classification and Control Technique of Surrounding Rock in Deep Mining Roadway

基于实验室试验、数值模拟计算、现场实测及力学理论分析等综合研究方法,研究深井回采巷道围岩变形力学特征及其影响因素,采用模糊聚类法对深井回采巷道围岩稳定性进行整体分类,再结合巷道顶底板与两帮围岩的岩性情况,进行巷道围岩次分类研究,由此提出适合深井回采巷道稳定性控制原则。

Based on comprehensive research methods of laboratory tests, numerical simulation calculation, field measurement and mechanics theory analysis, etc, this paper researches deformation mechanical characteristics and influencing factors of surrounding rock in deep mining roadway, classifies surrounding rock of deep mining roadway into overall classification by the fuzzy clustering method, and further classifies surrounding rock into sub - classification based on specific conditions of roadway roof and two - sidewalls. Afterwards, the paper proposes control principles which are suitable to maintain the stability of deep mining roadway.
