全粒级碎石水泥浆胶结充填质量控制

QUALITY CONTROL OF ALL-SIZE BREAKSTONE-CEMENT FILLING

在分段碎石胶结充填法试验研究过程中，在国内首次试验采用自然级配碎石胶结充填料自然混合、铲运机充填新工艺技术，充填体质量控制好坏直接影响着充填体强度、充填体抵抗爆破震动破坏的能力、充填体的自立稳定性和充填成本。本文详细论述了分段碎石胶结充填体质量影响因素与充填体质量保障措施。

In testing the staged breakstone-cement filling, a new technique was adopted first in China. Theprocess of the technique is that the natural breakstone and cement slurry are carried form surface filling stationseparatly into underground mixing point, where the cement slurry is spraied on the breakstone to form mixture,then the mixture is filled by LHD. The quality of filling mass directly affects on the strenth of filled mass and itsability of anti-failure caused by blasting vibration, its stability and filling cost. This paper discusses in detail thequality-affecting factors of the filling mass and its quality-ensuring measures.
