AP13268891 “Developing effective technological schemes for breaking thin deposits that provide reducing ore dilution, taking into account geomechanical state of the rock massif”, p.m. Suimbayeva A.M.

Relevance

The problems of developing technological schemes for optimizing the parameters of drilling and blasting operations (DBO), which ensure reducing ore dilution, taking into account the geomechanical state of the rock massif during breaking of thin ore bodies with highly fractured stable enclosing rocks, have always been an important task in the mining industry. Today, in almost all thin deposits, ore dilution is an unresolved problem. A feature of the deposit development technology is the over-planned ore dilution due to the sticking of the adjacent thickness of the enclosing rocks, which is caused by such properties of the massif as the unfavorable orientation of cracks in the enclosing rocks, the fractured structure of the massif and the weak adhesion of two different lithological differences (ore-rock), etc. The consequence of over-planned dilution leads to increasing the cost of transporting excess rock massif due to the sticking of the rock massif and processing ore, and ultimately to increasing the cost of minerals.

Optimization of the DBO parameters based on a complex of geotechnical works can be the answer to the question of how to reduce costs and to increase the efficiency of tunneling and stoping operations while maintaining the high quality of the extracted useful component. Therefore, reducing ore dilution is an urgent scientific and practical task.

Project purpose

Carrying out geotechnological studies on zoning of the deposit sections according to the stability rating of rocks according to the geological strength index for the development of optimal passports for drilling and blasting operations for breaking thin ore bodies, depending on their thickness, ensuring ore dilution decrease.

Expected results

As a result of the project implementation, optimal passports for drilling and blasting operations will be developed to ensure decreasing ore dilution during breaking of thin ore bodies based on the results of a complex of geotechnological (mine and laboratory) studies. They include testing rock samples for uniaxial compression, determining the quality of rocks RQD ( Rock Quality Designation), surveying rock fractures, taking into account lithology, watering of rocks and zoning of deposit sections according to the Geological Strength Index (GSI). Drilling and blasting certificates for cutting thin ore bodies will be optimized depending on their thickness and the value of the GSI index for a particular area of ​​the deposit.

AP13268843 “Studying the oil and gas potential of the pre-Mesozoic complex of the Aryskum trough of the South Torgai basin”, p.m. Madisheva R.K.

Relevance

In the Aryskum trough, oil and gas deposits are mainly confined to the Jurassic and Cretaceous deposits, as well as Devonian-Lower Carboniferous formations of the quasi-platform complex and disintegrated basement ledges. Now there are 52 oil and gas fields, the depletion of the initial recoverable reserves of which is quite high. Oil and gas manifestations of pre-Mesozoic formations up to industrial oil inflows allow drawing conclusions about the presence of a certain oil and gas potential in them. In this regard, determining the origin of oil and forecasting the direction of hydrocarbon migration is relevant for substantiating deep drilling in order to replenish the mineral resource base of the country.

Project purpose

Genetic typing of hydrocarbons, determination of fluid communication of structures and determination of the direction of migration based on the results of biomarker analysis and fingerprinting of oils from the fields of the Aryskum trough of the South Torgai oil and gas basin.

Expected results

Studying biomarkers in oil will make it possible to determine the conditions for the formation of oil, to correlate its composition with the geological age of the initial OM, to determine the nature of the redox situation during diagenesis, the lithology of rocks and the effect of microbiological activity and other geochemical parameters of oil formation.

By grouping oil footprints, one can easily identify the estimated objects and correctly build geological and hydrodynamic models of the deposit using only wellhead oil samples from wells.

Information for potential consumers

Today, one of the topical areas in the development of the coal industry is developing and testing technological resource-saving methods and active means of supporting mine workings with stabilization of the rock massif to achieve a high technical and economic effect and to improve the safety of mining operations.

Underground mine workings in the mines of the Karaganda coal basin are in the unstable state (according to displacements of the rocks of the roof, soil and sides), they are supported with significant material costs and labor intensity of work, which follows from the absence of justification for the compliance of their supporting parameters with the operating conditions in given mining geological, technical and production conditions. The adoption of sound technological solutions to determine the parameters of the support and efficient operation requires a geomechanical predictive assessment of the deformed state of the enclosing rock massif around the perimeter of mine workings. The development and implementation of technology and tools with justification of their supporting parameters, taking into account the stress-strain state of the enclosing rocks, will reduce labor and material costs in the operation of underground mine workings.

 

AP13268798 “Developing and industrial testing of technological schemes for strengthening the weakened zone of rocks when crossing a geological disturbance by a development working”, p.m. Khalikova E.R.

Relevance

Due to increasing the depth of mineral deposits development, mining and geological conditions are constantly deteriorating.

Improving the stability of mine workings is one of the most important tasks in the underground mining of mineral deposits.

The unsatisfactory state of mine workings causes indirect financial and labor costs that are difficult to take into account. This renders a negative impact on a number of processes associated with the coal mining technology (transport, ventilation, drainage, etc.). Therefore, the problem of stability of mine workings remains one of the most relevant and determining the efficiency of coal mines in various basins of the country.

The prospect for the development of the presented scientific area for underground work in the coal industry of the Republic of Kazakhstan currently depends on the use of the results of scientific and applied research and pilot testing in coal mines of the Karaganda basin. Therefore, pilot tests and commercialization of the Kazakh technology to prevent rock massif collapse in the areas of increased displacement due to various types of disturbances in the occurrence of enclosing rocks when driving underground workings based on numerical modeling of the stress-strain state of a rock massif is an urgent task in the field of mining operations in various mining and technical conditions of preparation and schemes of mining of coal seams.

Project purpose

The development of technological schemes for strengthening the weakened zone of rocks when crossing a geological disturbance by a development working, providing an increase in the stability of the rocks surrounding the working.

Expected results

As a result of the project implementation, technological schemes for mounting the developed supports will be developed, which will reduce the cost of supporting mine workings in the disturbed rock massif, commensurate in amplitude with the extracted seam thickness, while motivating work to improve the efficiency and safety of coal mining in the mines of the Karaganda basin requires improving methods to prevent impact increased rock pressure, forecasting geomechanical conditions in the mining of coal seams with introduction of promising methods to improve the mine workings stability.

The results of the project will be used in preparing educational and methodological materials in specialty “Mining” for bachelor, master and doctoral students.
