Sentence examples for of backfill slurry from inspiring English sources

The research results indicate that the most important factor affecting the conductivity of backfill slurry is the ratio of waste rock to tailings.

This could be caused by confinement effect of backfilling and the infiltration of backfilling slurry content into the failure zone improves mechanical properties of the broken pillars.

Finally, we conclude that, with an imaging time of only 0.04 s, ERT analysis has the potential to fully meet the real-time requirement of online monitoring of the backfill slurry transportation.

The conductivity of the backfill slurry reached a maximum of 3.8 mS/cm for a solids concentration of 50 wt%, particle size of 25 50 mm, and waste rock-to-tailing ratio of 70/30.

Using orthogonal experiments, we also analyzed the effects of the solid concentration, particle size, and waste rock-to-tailing ratio on the electrical conductivity of the backfill slurry.

The experimental results show that this material had excellent workability as fresh backfill slurry because of its high flowability and low bleeding rate, and the data also demonstrate that the material had good mechanical properties in a compressive test, as the hardening body of the backfill material reached around 7 MPa in 360 days.

Although the backfill slurry contained a large amount of industrial solid waste, the TCLP results indicate that none of the tested hazardous elements exceeded EPA limits, indicating that this backfill material is able to stabilize and/or solidify the hazardous elements very well.

The mechanical properties of backfill bodies are the key to a successful backfilling.

Although gob backfill is also called complete backfill, none of backfill techniques can obtain a filling ratio of 100%%.

The influences of backfill height and backfill stiffness are not relatively significant.

Figure 16 shows the mechanical properties of backfill mixtures.
