The object of research relates to the field of control systems for mining and transport machines in the development of deposits of solid minerals in an open way. The problem of reducing the cost of transporting 1 ton of rock mass and increasing the efficiency of these machines is being solved. The article develops an expert system for dispatching mining vehicles with a subsystem for selecting their innovative appearance with the ability to control their operational parameters, taking into account the stochastic conditions of the developed sections of the rock mass. The mathematical model for constructing the prospective appearance of a mining and transport machine, based on its functional and economic assessment, is reduced to solving the problem of optimizing the generalized criterion of the required efficiency. As an example of private indicators of their effectiveness in operation, there is an expert analysis of the evaluation of solution options, for example, structural-kinematic and operational parameters of these machines, etc. Innovative designs of a skip body of any size of its carrying capacity of single-rope and multi-rope steeply inclined skip hoists for highly profitable mining in quarries are substantiated. unlimited values of their depth and annual productivity. In the proposed study, the values of the forces of resistance to the destruction of a section of a rock mass, obtained by analytical and experimental methods, are refined by finding the optimal Kalman coefficient, which increases the efficiency of using mining and transport machines. The proposed methods provide the creation of innovative mining and transport machines with the ability to control their operational parameters, taking into account the stochastic conditions of the developed section of the rock mass

The industrial development of cities is the main cause of the destruction and degradation of natural resources around the world. Urbanization negatively affects the species composition of plants, the atmosphere and soil cover of areas of populated areas of large cities of the World. Tree plantations are the main mechanism for stabilizing the ecological situation in large cities and arid territories of the countries of the World. In this regard, in order to obtain a large number of genetically identical plants using their micropropagation, it is necessary to automate the main stages of this technological process. The result of the study is the creation of an adaptive phalanx gripper of a robotic complex for automating the technological process of handling operations. That will have a positive effect on solving the urgent problem of planting greenery in large cities and areas of arid territories not only in the Republic of Kazakhstan, but also in other countries of the World and represents a fundamentally new approach to solving the environmental problems of the Earth. The article substantiates various options for structural-kinematic schemes of the robot gripper, taking into account the stochastic conditions of its interaction with the overloaded object. Mathematical methods have been created for the selection and justification of the geometric, structural-kinematic and dynamic parameters of grippers for overloading plant microshoots and their computer 3D models. Software has been developed for modeling the functioning of a remotely controlled physical prototype of a mobile robot with an adaptive gripper for reloading microshoots from a transport tank to a cargo tank.

The article has to grapple with the problem of creating an economically efficient and environmentally friendly technological process for a development of solid minerals in open-pit mining. In many mining countries of the world today, the depth of many open pits is already 400–600 m or more. At the same time, the cost of transporting 1 ton of rock mass when operating a quarry whose depth is 400 m is 65–70 % of the total cost of extracting 1 ton of minerals. The object of research is technical devices for transport of rock masses in the technological process of development of solid useful deposits in open pit mining. The main reasons are the need to construct transport routes for them by withdrawing the sections of the rock mass on above them, as well their lifting capacity is limited because of they all do use highly energy-intensive machines for transporting rock minerals. In article has been justified a skip cable winch supplied with a wheels moving along on a railroad way by using only a gravitational counterweight device for transporting rock mass from a place of their formation to Earth surface. There have been created a prototype of a planar skip winch with four cables for practical implement in open-pit mining. The theoretical and experimental investigations of the prototype have being confirmed its performance. The created skip winch will accomplish its performancing without using any energy machines even under adverse climate conditions. Its affected would allow to make an open-pit effectiveness to soar and environmentally do friendly because of there are all but excluded any transport vehicles whether on gasoline or diesel oil
The object of research is the spent open-pit mines themselves where the proposed system could be applied. The primary reason for this studying is the following circumstance: up to the present time period, in all countries of the world, no methods of HLW disposal in a storage facility has been identified that is absolutely safe for any length of time, taking into account the impact of catastrophic natural emergencies and man-made emergencies. The research was conducted to address the problem of safely managing and storing HLW, leveraging the unique characteristics of spent open-pit mines, such as their large volume and geological stability, to prevent environmental contamination and ensure long-term safety. In the article has been justified a novel approach to the burial of sarcophagus containers with solid HLW in exhausted mining pits and studied the usabilities of the basalt sarcofagous container. Robust materials and advanced robotic systems proposed in the article aims to address the challenges associated with long-term radioactive waste disposal effectively. The robotic systems transfer the basalt container with HLW, ensuring personnel safety by minimizing human presence near radioactive materials. In the article have been established the distribution of temperature into the multi-layered composite structure of the basalt sarcophagous with HLW from 300 °C into the inner space to 50 °C onto on the its outer suffer where the thickness of each layers (from inner to outer radius) was respectively: for lead matrix: from r1=0.1 m to r2=0.2 m; for clay layer: from r2=0.2 m to r3=0.3 m; for basalt block: from r3=0.3 m to r4=0.4 m. The findings on temperature distribution are crucial as they directly affect the performance and longevity of the basalt containment system

In this article, a model is proposed for determining the parameters of the structural elements of a novel pincer robot for transporting plant microsprouts from a transport container in vitro to a working container with soil at the stage of their adaptation in soil during microclonal propagation. Scientific and practical result of the research is the creation of an innovative robotic complex of a manipulation device with a phalanx gripper for the transfer of plant microsprouts from a transport container in vitro to a working container with soil at the stage of their adaptation in soil during microclonal propagation, and the testing of its physical prototype in the adaptation of 3000 pieces of woody microsprouts. Plants with roots in the soil. The obtained research results will affect the scientific and technical potential and competitiveness of scientists in the Republic of Kazakhstan. In the Republic of Kazakhstan there are no studies on automation of the technology of microclonal propagation of plants for their mass production, the application of which would allow obtaining a large number of plants and reducing the cost of planting materials. Besides, the practical results of research on an innovative robotic complex will reduce the import of planting material of woody plants from other countries for the design of settlements in the Republic of Kazakhstan. In this regard, the need for native, high-quality planting material for woody plants will increase. One of the main solutions to the problem of landscaping in the settlement areas of the Republic of Kazakhstan is to obtain native high-quality planting material for woody plants by microclonal propagation.
