IMPROVING OF THE EFFICIENCY OF CLEANING OF THE BOTTOM OF THE BOREHOLE FROM THE CRUSHED SLURRY ON THE BASIS OF IMPROVING OF THE CONSTRUCTION OF A THREE-BALLCHISEL

Аннотация

In terms of the problems of effective use of reserves in the technological processes of drilling, it is important to wash the drilling scaffold, that is, to effectively clean it from the crushed slurry. Cleaning the drilled borehole bottom combines three processes that differ from each other: cleaning the bottom surface from the crushed slurry, cleaning the bottom wall environment and cleaning the ore-cleavage device from the adhesion of the slime is important. In this article, the construction of the ore-shredding device has been improved in order to effectively clean the drilled scaffold from the cuttings and eliminate the negative consequences of the slurry regime. The results of the experiment-test showed that the mechanical speed of the drilling of the scaffold and the increase in the performance resource of the drilling Hopper were achieved.
