Paste Pumping Filling Process - China

Paste pumping filling process

Technical introduction

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.

Technical innovation:

Except for satisfying long-distance pumpability, it

also gives important considerations to satisfy the technical

requirements for temporary pump stop and short-distance

interval conveying.

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.
