Disintegration Product

The work is aimed at determining parameters of advance borehole stoping by hydraulic monitors leading to rational use of reserves structured according to ore types at deposits by means of advance stoping with selective disintegration of high-grade martite ores. The research methods include experimental investigations of parameters of breaking a high-grade martite ore massif by high-pressure water jets of borehole monitors; laboratory studies of technological properties of hydrodisintegrated products and their concentratibility; theoretical generalization of experimental data. The research has resulted in developing experimental borehole hydraulic monitors and determining basic technical parameters of high-pressure water jets; determining regularities of hydraulic monitor disintegration of high-grade martite ores considering structural and mineralogical characteristics of the ores and hydrodisintegration modes; proving the fact that the process of high-grade martite ore disintegration by monitors is also the process of ore disintegration to the level of ore mineral grain release providing the higher quality disintegration product after subsequent dewatering than that of the initial one. The scientific novelty of the research consists in determining a criterion of hydrodisintegration of martites, conditions of forming a required fractional composition of monitor disintegration products through controlling stability of a pulse of the water jet action on the stope face. The practical relevance of the monitor breaking process in conditions of mining units at deep levels of Kryvbas underground mines consists in providing advanced stoping of rich martite ores through raises and obtaining a new kind of product – martite superconcentrate.

Removal Equipment

Ship rust removal is an import part of ship-repair and shipbuilding process. Using high pressure water jet equipment causes no environmental pollution. The control and detection of high pressure water jet equipment is the key technology to ensure the system works properly. This study, in light of research on software programming of control system of ultra high pressure water jet ship rust removal equipment, establishes a control system based on PLC through the analysis of the structure and principles of the ultra-high pressure water jet equipment. On the basis of designing hardware circuit of PLC control system, this study mostly analyses software program, and experimental test suggests that the software programming can meet the requirements of system security.
