jan 01, 2021 the results of the change in the rheological properties of the backfill mixture based on the waste of water-soluble ores are interesting from a scientific and practical point of view when simulating its emergency stop when moving through a pipeline, since the most extreme version of the emergency stop of the filling pulp was studied using this type of filling material as an example.may 10, 2021 author jiwei bian mamadou fall sada haruna abstract cemented paste backfill a soft concrete-like material, is extensively used in underground mines worldwide for ground support andor mine waste disposal. one of the most important ingredients in cpb is cement but it is expensive and can amount to 75% of the cost of the It is common practice to mix backfill samples in the lab using tailings, sand, andor rock samples, based on the mix design used at the mine site. the backfill is typically placed in or cylinders and cured at room temperature in 100% humidity until ready for breaking.
Determining The Rheological Properties Of Mine Tailings
sep 14, 2015 To determine if tailings can be pumped with the existing pumping equipment, the viscosity and the yield stress need to be measured. the yield stress value is strongly dependent on solid content of the slurry. australian company rheology solutions defines these important rheological properties as follows:maxon provides equipment for processing tailings from mining operation; paste treatment and backfill applications for underground hard rock mines; remediation of existing and closed mine tailing ponds; and tailing processing for coal fired power plants.mining with backfill is a requirement in the industry as it is an important aspect of many mining methods and is a solution to many rock stability issues. when a mine plans to use backfill there are a number of considerations to be made with regards to type
Types Of Mine Backfill Mininginfo
hence, mine operators are moving towards less water in the fill to decrease cement and binder consumption; flow velocities in excess of ms are required to maintain a homogeneous dispersion of the fill components in the slurry; paste backfill. paste backfill is a high density backfillresearch article sampling and mechanical testing of backfill in large mined-out area deng ,1,2 jiang,3 and duan chool of civil engineering and mechanics, xiangtan university, xiangtan, hunan china nstitute of mining engineering, guizhou institute of technology, guiyang, guizhou china aolou iron mine, jinan mining Co ltd liuan, anhui chinacemented paste backfill is an economic and environmental friendly technique applied in underground mining for supporting surrounding rock and replacing the pillar. however, little is known about the temperature effects on cpb in mines having a large temperature fluctuation. the main purpose of this research was to investigate the effect of temperature change on the rheological properties

Backfilling In The Underground Mining Industry
mar 05, 2014 backfilling in the underground mining industry backfilling IN the underground mining industry. By ray brown. have often been asked by people outside the mining industry what backfilling is and why it is necessary to the industry.mar 03, 2021 thus, this study aims to investigate the effect of temperature and time on the rheological properties of cpb samples with different amounts of sodium silicate and different binders. the results show that the yield stress and viscosity of cpb with sodium regression analysis model was established for the rheological properties of mine backfill paste. the model has few factors and high correlation, so it can simply and efficiently predict the rheological properties of mine backfill paste and guide engineering practice.
