The civilisation is impressive human achievement, with development of social setups and technical spreads, operated by ‹knowledge›, via relational and e manufacture modes. The trails include collective breakthroughs and technology revolutions, leading to amazing progress directly yielded by human intelligence, as if cosmic rationality or godly wisdom originates it. The progress, based on the bounded earth, shall stop due to source lessening and waste piling, unless safe retrieval occurs. The social settings and technical inventions analyses look as if the intelligence leads to creative chances, adding before not existing possibilities: the ‹knowledge› is not just encoding of items or facts to be shared, but also resourceful concept formation. The thought is skill, backing societies and discoveries, and allowing new findings: the artificial intelligence allots parallel talent to synthetic hands/minds. The growth sustainability can follow optimistic leeway: the earth/universe unbalance tells that the former never affects the latte; fitting managing robots can fetch raw resources to earth and remove toxic wastes from it, negligibly upsetting the universe.

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.

In this article, firstly, the Taj Mahal is based on the Samanid mausoleum in Bukhara, the cube dome is based on spherical shapes, secondly, the doors on both sides of the two mausoleums are made, and thirdly, the inner and outer parts of the Taj Mahal are based on the octal model of the universe. Our scientific hypothesis is expressed in the fact that it has been found that it is symbolically referred to here as the Taj Mahal, where the two worlds have attained bliss.

An analysis of the performance of quarry hydraulic excavators shows that many excavators used in mining operations operate at lower productivity than those specified in the technical description. This can be caused by unexpected interruptions during operation, rapid failure of parts and unreliable operation of excavator personnel.

This article discusses the development of a protective element at the base of the jaw section of an excavator bucket that is technically and cost-effective in increasing the efficiency of quarry excavators. In addition, the results of experiments and their analysis of the proposed element of the protection of the base of the improved bucket jaw.

Maximum Power Point Tracking (MPPT) algorithms are significant in PV systems due to they reduce the PV panels number that necessary to reach the target output power, lowering the PV array expense. This research gives a simulated comparison of two essential MPPT techniques, incremental conductance (IC) and perturb and observe (P&O) utilizing single diode and Thevenin comparable models. The essential parameters involving voltage, current, and power output were traced for both methods using a DC-DC boost converter. The results of stimulation revealed that for the two tracking algorithms the single diode module gives higher output power in comparison with the Thevenin equivalent model but for the IC algorithm the Thevenin equivalent model gives less output signals ripple.

Studies have been carried out to determine the optimal bench height, recommendations have been made to improve the completeness of extraction of gold-bearing ore and recommended excavation and loading equipment for small-scale deposits. The change in the values of losses and impoverishment of the ore, as well as the gold content in the ore, depending on the height of the ledge for various thicknesses of ore bodies, has been established.

An analysis of the performance of excavators shows that many hydraulic excavators used in mining companies operate at a lower efficiency than those specified in the technical description. This can be caused by unforeseen downtime, rapid failure of parts and unreliable operation of excavator workers.

This paper discusses the development of cutting elements with high service life to increase the efficiency of quarry excavators. In addition, the results of experiments on the proposed improved denture teeth and their analysis are presented.
