摘要: Solid waste backfilling techniques are widely employed in the coal mining industry and pressure propagation characteristics of solid materials important considerations evaluating a overall effectiveness. This paper presents an experiment that evaluates different particle sizes. The results show with larger sizes have higher properties, while smaller less capable transferring pressure. Analysis indicates there is exponential relationship between influence factor (I) vertical distance (Z/D), where Z/D depth below center loading platen divided by diameter. There also GaussAmp I horizontal displacement (L/R), L/R abscissa radius. indicate more than 70 % dissipated range 0–2.75 virtually all within 0–5. were applied Wugou mine to evaluate effectiveness compaction methods mechanism can work effectively.
