Paste Pumping Filling Process - Chinaprice: contact company for price
The paste pumping filling process refers to that when the
filling upscaling cannot achieve gravity-flowed conveying,
structural flow conveying method will be applied to fill the
filling slurry into the worked-out section through pumping
filling slurry. The process is suitable for high-
concentration slurry filling, can reduce the dehydration
rate of underground filling slurry and improve the strength
of filling body.
The paste pumping filling process comprehensively uses a
number of new modern industrial technologies: fine
particulate material dewatering technology and equipment,
paste pumping technology and equipment, paste preparation
technology and equipment, advanced automation and control
system. Therefore, reasonable mixing slurrying process and
conveying equipment shall be selected to satisfy the paste
pumping filling process, thus to create good economic
benefits for mines.
Except for satisfying long-distance pumpability, it
also gives important considerations to satisfy the technical
requirements for temporary pump stop and short-distance
High liquidity and reasonable gradation and concentration
can make the paste have good liquidity in the pipeline under
the role of gravity and other pressure.
It reduces pipe friction resistance losses; it adds
a certain amount of admixture, which can guarantee the
workability of the paste and improve the fluidity of paste.
It adopts the new-type cementing filling material
with self-developed and independent intellectual property.
Under the same strength requirement, the amount of cementing
material is 2/3 of that of cement, which can reduce the
filling cost. Meanwhile, it can improve the workability and
the stability of the slurry.
