AP14972804 “Developing software for technological preparation of production based on a formalized design methodology”, p.m. Savelyeva N.A.

Relevance

In the context of the innovative and industrial development of the Republic of Kazakhstan, requirements for reducing the development time for technology (technological processes and their equipment) have increased with improving its quality. This becomes especially relevant with the wide development of production systems. The effective use of these systems requires automation of technological preparation, including the design of manufacturing technology, which is the most labor-intensive process.

At present, there is a gap between the intensification of production itself and the pace of its technological preparation. The low rate of pre-production restrains the production pace and significantly reduces the effectiveness of measures to improve production. The most important means of intensifying production in mechanical engineering is the automation of technology design, which should ensure the automation of engineering work, both in routine and creative areas. Design automation is a tool for solving production problems at a new, higher quality level.

Project purpose

The project purpose is to develop a system for computer-aided design of technological processes of machining by cutting parts in conditions of single and small-scale production.

Expected results

As a result of implementing the project, a formalized methodology for computer-aided design will be developed and based on it software for technological preparation of production in the conditions of single-piece and small-scale production, ensuring the design time reduction, eliminating subjective errors, reducing production costs and quality losses.

A four-level mathematical model based on the multicriteria analysis will be developed, taking into account determining the optimal sets of cutting tools, the best options for technological processing routes, taking into account the magnitude of production costs and quality costs.

A new methodology of selecting a rational option for a technological process will be developed, which will reduce the time for introducing new design developments into production.

Experimental studies will be carried out regarding the use of the formalized method of automated design of technological processes for manufacturing parts at machine-building enterprises. Based on the methodology obtained, a software product will be developed. Recommendations will be received on the practical use of the developed software products and their testing. A new methodology of selecting a rational option for a technological process will be developed, which will reduce the time for introducing new design developments into production.

AP14972877 “Developing methods of forecasting sudden coal and gas outbursts based on studying coal nanocoating”, p.m. Maussymbayeva A.D.

Relevance

The relevance of the work lies in the fact that the developed empirical model for determining of the quantitative nanostructure of the surface layer of the coal material of the Karaganda basin determines the processes that occur during interaction with the external environment, and new methods of affecting the coal seam to increase gas production taking into account size effects. A model of the stress-strain state of coal seams was developed based on equations with a moving boundary of the phase interface, and it was theoretically shown that all the processes associated with the gas movement of coal seams both in the free state and during mining has an autowave character, which determined the nature of gas release and destruction of coal seams; it was theoretically established that the coal strength was determined by surface energy; it was shown that the greatest effect was given by degassing (taking into account hydraulic fracturing with acid) from the surface with vertical wells and drainage works, which were carried out at the distance of at least 20 meters above the layer; it was shown that the flow of hydraulic fracturing fluid in the well broke down and turned into a mixed-free-jam flow.

Relevance

Serpentinite in dunites is widely developed in the mine zone of the Khromtau deposit. Serpentinite is common in pyroxene dunites. The named types of rocks extend to the depth of 35÷110 m from the earth’s surface. The maximum degree of drying is observed at the depth of 10-20 m. Here, the rocks were formed by fine-grained rocks and turned into a clayey mass.

With increasing the depth, the rock strength increases. Compression resistance of low-tonnage rocks and ores at great depths varies up to 60÷120 MPa.

According to geological data, the main ore deposit is mainly represented by solid and densely interspersed ores, and rocks in the deposit are represented by serpentinized pyroxene-free dunites, pyroxene dunites and peridotites to varying degrees.

Project purpose

The purpose of the work is forecasting the stress-strain state (SSS) in the massif of rocks within the limits of the stoping operations effect at the -480 m level when using the development system, and calculating the bearing capacity of the types of reinforcement used in the mine of the Khromtau deposit.

Expected results

As a result of implementing the project, the following results will be obtained:

– analyzing mining-geological and mining-technical conditions of mine development, analyzing methodological determination of the stress-strain state as well as numerical analysis of the stress-strain state of the rock massif;

– predictive assessment of the massif SSS that is based on the use of effective numerical methods and allows increasing reliability of forecasting the “mining-geomechanical” situation in the mining area;

– calculation of loads on reinforcement of workings in enclosing rocks and in ore massif and calculation of bearing capacity of types of reinforcement used in the mine on the basis of the numerical analysis.
