Research o method of parameter measure of unclassified tailings-slag paste;

Study on Paste Pneumatic Bottler Placer;

Based on the basic theory of pipe column flow, the pumping resistance of backfill paste was analyzed and over 90?m long horizontal loop pipe tests driven with a concrete pump were carried out in situ to compare calculated pumping resistance with measured ones.

Based on the basic theory of pipe column flow, the pumping resistance of backfill paste from empty area were analyzed and over 90m long horizontal loop pipe tests driven by a concrete pump were carried out in order to compare calculated pumping resistance with measured ones and the effect of pumping aids on the pumping resistance of backfill paste.

Experimental study on rheology performances of paste backfilling slurry;

The mass concentration of the paste backfilling materials is one of the key factors affecting the performance of backfilling and the measurement error in raw materials and in moisture test are two main factors affecting the mass concentration.

Aiming at paste backfilling of underground Open-stope,this paper put up systematic and deep research to theory and technology.

Influence factor analysis of paste filling material strength;

Test study of cement adding mode of paste filling;

Study on Surface Subsidence with Paste Filling under Village;

Abradant,organic matter,additives and technology are studied in this paper.
