To assess the stress state of a rock mass, the core disking method is proposed as a basic method. The degree and categories of impact hazard of sections of the rock mass are estimated. Due to the impossibility of solving many problems by geomechanical only field studies.
The reliable efficiency of the use of the finite element method and the boundary element method in predicting the impact hazard of the field sites a priori is shown.
This article is devoted to discuss what kind of religion people worshiped in the Nawbahar temple in Balkh in pre-Islamic times. In medieval sources there is different information about character of a cult in the Nawbahar temple in Balkh. According to some sources, this temple was a temple of fire worshipers, i.e. Zoroastrians, according to another sources – it was a temple of idolaters, i.e. Buddhists. I think that the Nawbahar temple was built in reign of the Turkic qaghan El-Tegin (Parmuda, Nili-Khan) and in VI–VII centuries AD it was a cult centre of the Manichaeans.
The article analyzes the fact that in the stories of Nodir Normatov, a writer with a unique style of prose, the use of poetic interpretations of ancient images belonging to the most ancient layers of Uzbek mythology to symbolic metaphors, myths and legends served to illuminate the spiritual world.
The flow model of the crushing and crushing equipment is important because it allows the stone material to slide down through the crushing chamber. The crushing or crushing characteristics were achieved by testing the rock based on spring compression during crushing under controlled conditions. The input data (CSS) includes parameters such as speed, stroke, camera geometry, distribution of transmission values and mechanical properties of the material. The performance of a traditional cone crusher, which shows the performance for ore of various products. The nominal design of the conical crushing and crushing equipment is made. At this stage, it is possible to calculate a set of nominal parameters characterizing the chopper chamber. The nominal stroke and layer thickness are determined at each point of the chamber cross section. The same material was used in modeling and field tests. After each compression test, the material was screened. Distribution of the sizes received at each check. A selection function with two variables adapted to experimental data. b) functional representation in 3D.

The article examines the main factors that affect the nature of the manifestation of mountain pressure. The physical and mechanical properties of rocks are the main factor determining the nature of the manifestation of rock pressure, their stability and their tendency to self-collapse.
The natural acids were utilized at the pace of 2 % for 50 g RP in 250 ml conelike cups. These examples were kept in a hatchery at 250c for a very long time and broke down for Mehlic-3 extractable P and pH esteems following 20 days stretch. Measurable examinations were made and most extreme P centralization of 1.52% was seen in the treatment of oxalic corrosive blended in with RP followed by the medicines of RP blended in with humic corrosive with P grouping of 0.368%. Quick expansions in P dissolvability from RP by blending in with oxalic acids were noted up to 60th long stretches of hatching period and afterward stayed stable after this period. Solubilization of P from RP by blending in with other natural acids was conflicting. The pH in treatment of citrus extract blended in with RP was noted as 5.64, trailed by the medicines of oxalic corrosive with pH upsides of 6.31. A sensational expansion in pH worth of 9.33 was seen in the treatment of RP blended in with humic corrosive. It is on the grounds that the humic corrosive contains sodium salt and sodium hummate causes expansion in its pH esteems.

This article analyzes astral myths and mythological representations of our ancient ancestors, who lived in Central Asia, and reveals their specific features, genetic origins and symbolic interpretation in the monuments of material culture.
In the Twenty-First Century, in the context of globalization processes, special attention is paid to the study of the contribution of religions to the development of world civilization, spirituality and enlightenment, because spiritual culture determined the progress of society and, since ancient periods, has been closely associated with religious views and beliefs. This definition is fully applying to Buddhism, that existed for many centuries in the south of Central Asia, including in the historical and cultural region of Bactria, along with Zoroastrianism and other religions.
Central Asia is considered as a territory of distribution of various religious views, religions and teachings by the world's leading research institutions since ancient times. In this regard, special studies have been conducted and their results were published in many scientific publications. In particular, Uzbek and foreign scientists carried out fundamentally important archaeological work with the aim of studying the Buddhist monuments of Tarmidh-Termez, as well as identifying the features of the spread of Buddhism through this region to Margiana, Sogdiana and East Turkistan. From this point of view and out of the need to analyze other topical issues (spiritual and material culture, fine arts, numismatics and epigraphy, reconstruction of the functions of Buddhist centers), additional research based on new approaches is an urgent scientific task.
The article describes the method of influence of the explosion action on the stability of the instrument array in ore quarries during operation. The voltage of the instrument array from the explosion action on optically active models was studied. In technological processes, the stability of the sides of rock and semi-rock rocks and the value of the angle of inclination of the sides is most affected by drilling and blasting. To ensure the safety of the sides of deep quarries, we recommend the method and management of deformation processes. Using this method, it is possible to create a simulation of the pressure of detonation products on a static and dynamic setting.
Currently, in the mining industry of our Republic, there is an increased interest in the issue of filling the voids formed in the exploited ore deposits. The increase in the extraction of minerals from the ground, the preservation of the rock layer above the aquifers, as well as the safe performance of mining operations, led to the development of the filling system in existing ore deposits in our country and abroad [1].
The article examines the principles of operation and distribution of cone crushers when crushing nonmetallic materials.

The development of methods and means to improve the efficiency of the mining facility is aimed at improving the efficiency of the use of raw materials concentrated in deposits of natural and man-made origin. This increase in efficiency is manifested through maximizing the content of commercial ore shipped for processing, creating prerequisites for increasing the shipment of commercial ore and increasing the productivity of the processing plant. Maximization of the content in commercial ore is based on the developed scheme of cyclical increase in the efficiency of resource potential use for the entire period of field development, supplemented by an improved method of current mining planning based on anisotropy of contents and dynamic conditions.
The environments of deposition play a vital role during hydrocarbon formation, migration, trapping and storage. Since the reservoir rocks are a function of their depositional environments, the successful tapping of hydrocarbon from its host rock when wells are drilled depends largely on the petrophysical characteristics of the reservoir rocks which in turn originated from and are influenced by their depositional environment. The reservoir facies in Niger Delta shows a broad range of characteristic sedimentological complexities that gave rise to subsurface geological, drilling and production problems occurring in UK Field. The problems include inaccurate determination of environments of deposition, imperfect stratigraphic correlations and reservoir top uncertainty across the UK Field which are targeted by this research in other to help resolve these challenges facing oil and gas industries in the Niger Delta basin of Nigeria. The research findings will assist in the evaluation of depositional environments and well-to-well lithologic correlation within the UK Field and Niger Delta Basin at large. It will also help to unravel major causes of reservoir top uncertainty in UK Field. Also, it will help in future planning and drilling of new wells within UK Field. The determination of the depositional environments of UK Field reservoir sands were carried out to determine the depositional environment of reservoir sand bodies based on data from seven (7) wells. The determination of depositional environments of sand facies penetrated by wells UK1, UK2, UK3, UK4, UK5, UK6 and UK8 was achieved through a side-by-side comparison of their log suites to standard log motifs. Results of facies analysis showed that the reservoir sands belong to mostly (i) fluvial channel, (ii) barrier bar, (iii) lower-middle shoreface, (iv) distributary mouth bar, (v) distributary channel, (vi) point bar and (vii) tidal channel environments that belonged to parts of a deltaic system. Lithologic correlation result reveals the existence of good correlation among all wells in UK Field due to good geological similarities except well UK8 that failed to correlate perfectly with others thereby establishing the existence of reservoir top uncertainty within UK Field. Therefore, reservoir top uncertainty within UK Field is geologically controlled.

One of the main components in the production of building materials is silicon, and an increase in the production of building materials means an increase in the number of workers engaged in their processing. Silicon is a brown powder or gray crystals. It is a part of sandstone, graphite, sand, coal mine waste rock, molded earth and porcelain pieces. Silicon is also one of the main components of dust in many industries, especially porcelain and abrasive. Silicon dioxide is a component of quartz, quartz and other materials. Human inhalation of silicon-containing dust leads to the development of silicosis, which manifests itself in the form of pulmonary fibrosis and increasingly impairs their function.
