摘要: 作为实现“绿色开采”的主要技术手段和当前解决“三下一上”压煤问题,控制地表沉陷效果最好的矸石膏体充填开采技术,其充填效果评价过去一直采用的是地表岩移观测的方式,但是采用地表岩移观测的方式周期往往较长、费用较高、劳动量大。为此,基于KJ216顶板压力在线监测系统,研制了采空区膏状充填体在线监测系统。对采空区膏状充填体长期受力、变形和水化程度进行长期监测,综合评价充填效果。实践证明该系统现场应用效果良好。

Abstract: Gangue gream-body filling is the main technological means of realizing green mine and the best technology to solve the problem of mine under water body,building and rail,and on karst water body and to control surface subsidence,which used the surface movement observation to evaluate the filling effect in the past,but cycle is often longer,cost is higher and amount of labour is larger using the mood of surface movement observation.To this point,developed the on-line monitoring system of paste backfill in the goaf,based on the KJ216 monitoring system of plank pressure.Comprehensively evaluated the filling effect through long-term monitoring of long-term stress,deformation and hydration degree of paste backfill in the goaf.The practice showed that the system worked well on site.

Key words: Gangue backfill paste, Backfill, On-line monitoring, Evaluation
