Jianxin Fu s 28 research works with 415 citations and 1 579 reads including Influence of basalt fiber on pore structure mechanical performance and damage evolution of cemented tailings backfill
tailings impoundments are among the largest structures created by human kind The safety of the tailing reservoir is one of the major concerns The characteristics of tailings are a result of the composition of the parent rock and the method of ore processing In this paper the two types of tailings from an iron mine in South China were
Mechanisms responsible for the caving of the strata overlying Chengchao Iron Mine were investigated by analyzing in situ deformation monitoring results and the distinctive engineering geological
Iron tailings 1 Iron tailings authors developed nucleated glass of CaO MgO Al2O3 SiO2 system by using the iron tailings of Beijing Miyun Mine as raw materials 。
Investigation on the Prevention and Treatment Measures of Seepage Failure of the Fine Grained Tailings Dam A Case of Iron Tailings Reservoir in Mining Metallurgy & Exploration IF DOI Dayu Long Changhong Li Yongyue Hu Juzhou Li Yu Wang
The particle size distribution in tailings notably influences their physical properties and behavior Despite this our understanding of how the distribution of tailings particle sizes impacts in situ pollution and ecological remediation in in situ environment remains limited In this study an iron
Study on Ecological Restoration of Chengchao Iron Mine Tailings in Hubei Province; of Extraction and Kinetics of Leaching Vanadium from Vanadium Titanium Magnetite Tailings
According to the history and current situation of ground caving in in the eastern Chengchao Iron Mine a 3D surface model of ground caving in was reconstructed with the help of a 3D laser scanning
Taking the Chengchao Iron Mine as the engineering background Tan et al used the method of combining a theoretical calculation a numerical simulation and a physical similarity experiment to
Key takeaway The compressive strength of mine filling material is positively correlated with cement sand ratio age and slurry concentration enabling efficient mine filling and reducing environmental impact Experimental Research on the Performance of Cemented Whole tailings Filling Material in Chengchao Iron Mine Mei Linfang 2012
Mine filling can protect the limited land resources save expenditure realize no wastes emission and eliminate the potential mixing proportion experiment of filling material which consisted of the full tailing taken from the Chengchao iron mine as the aggregate and the common 425# cement as the cementing was carried settlement test viscosity test and slump

As the world s largest resource production and consumption country China is rich in mineral resources but its per capita occupancy is lower than the world average In this context mining enterprises need to choose efficient green and safe mining methods The backfilling method has been paid more and more attention in domestic mines because of its
mines are directly applied to metal mines without consid ering the differences This has caused considerable safety issues in many metal mines such as Chengchao Iron Mine Research on the mechanism of rock strata movement induced by metal mining activities is very important Atkinson et al 1975 Rice 1934 and Boyum 1961
By using the proposed drainage system the height of the tailings dam of this mine can be increased from 45 m elevation 2015 m up to 60 m elevation 2030 m which will increase by 8 million
This research study investigates the extent of heavy metal pollution and pollution trends in agricultural soil in mining areas during different time periods A total of 125 soil samples were collected from two mining areas in China the Chengchao iron mine and Tonglushan ancient copper mine The samples were analyzed for various potentially toxic
