综放采场上下位岩层结构相互作用对垮落带分布影响的研究

Study on upper and lower Strata Structure influence on caving zone distribution in Fully Mechanized Sub Level Caving Faces

本文以综放采场上覆岩层的下位岩层形成散体拱结构为前提,通过对采场围岩分区及其力学模型的建立,深入分析了采场上位岩层结构与下位岩层结构相互作用对不规则垮落带和规则垮落带分布的影响,丰富了人们对综放采场上覆岩层活动规律的认识。

Under the precondition of granular arch structure generated by lower strata of overlying strata in fully mechanized sub level caving faces, through the division of stope wall rock into partitions and the establishment of mechanical model, the paper analyzes deeply the influence on distribution of irregularity caving zone and regularity caving zone, enriches people＇ s ureterstanding on activity law of overlying strata in fully mechanized sub level caving faces.
