摘要: 从结构分析方面对作为人工顶板的充填体的破坏规律进行了探究。分别从采场充填管头安放位置和充填料浆进入采场时的流动特性方面进行了综合因素分析,从而确定充填体的结构。提出了作为人工顶板的充填体的破坏型式与充填体结构之间的关系,对实际矿山的顶板管理和充填优化有一定的参考意义。

Abstract: The failure law of artificial filling roof based on structural analysis was researched.It consists the placement of filling pipe head and flow behavior of filling slurry to ascertain the structure of filling body.The relationship between failure modes and the structure of filling body is proposed.It provides a reference meaning for mines to roof management and filling optimization.

Key words: Filling body, Artificial roof, Structural analysis, Failure law
