Water Quality Characterization Of An Eastern Coal Slurry. [PDF]

open access: yes, 1985
This paper describes an experiment conducted to characterize the slurry water resulting from an eastern coal. For characterization, 29 water quality parameters were measured on slurry filtrate sampled at various pumping times in a small pipe-loop system ...

Research on the mechanism of fracture grouting diffusion and its application based on slurry-rock mass coupling effect

open access: yesMeitan kexue jishu
The deep mining process of North China type coalfields is highly threatened by the threat of water damage from the floor limestone aquifer. By arranging grouting holes reasonably to inject a large amount of slurry into the aquifer that directly threatens

The Simulation and Water Quality Characterization of a Coal Slurry Involving Eastern Coal [PDF]

open access: yes, 1983
The water quality characteristics of a coal slurry were found to vary widely, depending upon the coal used and the use of a corrosion inhibitor. The coal-water interactions were evaluated in a pilot-plant closed-loop coal slurry pipeline. Pulverized coal

Study on stability of coal water slurry under different coal water slurry dispersants by using stability analyzer

open access: yesIOP Conference Series: Materials Science and Engineering, 2019
Abstract The stability analysis of CWS by Turbiscan Lab stability analyzer not only can clearly observe the change of the supernatant layer in the slurry, but also can observe the change of the turbid area. It can objectively reflect the agglomeration and flocculation in the slurry, Settlement and a series of changes.

Structural evolution of coal sludge filter cake and optimization mechanism of combined chemicals in the process of filtration pressing

open access: yesMeitan xuebao
The structure of coal sludge filter cake has an important influence on the dewatering effect. In this study, the characteristics of the filter cake structure and its evolution law in the process of filter press dewatering were investigated by using the ...

Site tracing experiment on the diffusion range of regional grouting renovation under the coal seam floor aquifer

open access: yesMeitan xuebao
In recent years, to liberate coal resources from high pressure limestone water on the coal seam floor, North China Coalfields have generally adopted surface directional drilling technology to carry out regional grouting reinforcement and transformation ...
