AP13268891 “Development of effective technological schemes of stripping of low thickness deposits, providing reduction of ore dilution, taking into account the geomechanical state of the rock massif”, scientific supervisor of the project Suimbayeva Aigerim Maratovna
Relevance. Creation of technological schemes to optimize the parameters of drilling and blasting operations (DBO), providing a reduction in ore dilution, taking into account the geomechanical state of the rock massif when stripping low thickness ore bodies with highly fractured stable host rocks, has always been an important task in the mining industry.
At present, ore dilution is an unsolved problem in almost all low thickness deposits. The peculiarity of the field development technology is the overplanned dilution of ore due to the seizure of the adjacent thickness of host rocks, which is caused by such properties of the massif as unfavorable orientation of fractures, host rocks, fractured structure of the massif and weak cohesion of two different lithological differences (ore-rock), etc. The consequence of excessive dilution leads to increased costs of transportation of excessive rock mass due to rock mass seizure and ore processing, and ultimately to an increase in the cost of the mineral.
Optimization of DBO parameters on the basis of a set of geotechnical works can be the answer to the question of how to ensure cost reduction and increase the efficiency of tunneling and cleaning works while maintaining the high quality of the mined mineral component. Consequently, reduction of ore dilution is an urgent scientific and practical task.
Project objective
The objective of the project is to carry out geotechnological research on zoning of the deposit areas by rock stability rating according to the geological strength index for the development of optimal drilling and blasting passports for mining of low thickness ore bodies depending on their thickness, providing a reduction in ore dilution.
Expected and achieved results
In the course of the project implementation, research was carried out to study the regularities of reducing the seismic impact of the blast force on the surface massif and the efficiency of pre-developed DBO passports ensuring ore dilution was assessed. The most effectively used rating indicators of stability to mining and geological conditions of “Zholymbet” deposit were substantiated and zoning of the deposit areas by stability category was performed. A geotechnical block model was created to assess the geomechanical condition of the rock massif around the cleaning block, taking into account the influence of blasting quality and geological strength index. DBO passports were developed for stripping of low-power ore bodies taking into account their thickness, geological strength index and changes in blast hole parameters. Pilot tests of the developed technological schemes for mining of low-power ore bodies were carried out in the conditions of the “Zholymbet” mine.

Information for potential users
Drill and blast passports will work to minimize the seismic impact on the rock mass, which in turn will reduce ore dilution to the design rate. Reduction of ore dilution will reduce the volume of excess rock mass transportation, stabilize the geomechanical condition of the rock mass and improve the safety of rock mining.
Field of application. When developing passports for drilling and blasting operations for the extraction of low-power ore bodies.
AP13268843 “Study of the oil and gas potential of the pre-Mesozoic complex of the Aryskum trough of the South Torgai basin”, scientific supervisor Madisheva R.K.
Relevance
In the Aryskum trough, oil and gas deposits are confined mainly in Jurassic and Cretaceous sediments, as well as Devonian-Lower Carboniferous formations of the quasi-platform complex and disintegrated protrusions of the basement. At present there are 52 oil and gas fields, the depletion of initial recoverable reserves of which is rather high. Oil and gas occurrences of pre-Mesozoic formations up to commercial oil inflows allow to draw conclusions about the presence of certain potential of oil and gas bearing capacity in them. In this regard, the determination of the origin of oil and the forecast of the direction of hydrocarbon migration is relevant to justify deep drilling in order to replenish the mineral resource base of the country.
Objective
Genetic typing of hydrocarbons, determination of fluid-communicability of structures and determination of migration direction based on the results of biomarker analysis and fingerprinting of oils from fields of Aryskum trough of South-Torgai oil and gas bearing basin.
Expected and achieved results:
The results of the analysis of new data on hydrocarbon geochemistry of the South Torgai basin allowed us to draw the following conclusions:
- According to the results of pyrolytic analysis of the core, which allows estimating the generative potential of the oil-producing rock, it was found that the studied samples have potential from bad to good in terms of Sorg content (from 0.47 to 1.41), as well as in terms of S2 parameter (from 1.1 to 9 mg HC/g of rock).
- Determination of the kerogen type by the graph of Sorg dependence on hydrocarbon potential showed that the vast majority of the studied samples belong to the kerogen type II and III, and only the sample from the depth of 1897.36 m, with maximum TOC and S2 are within the kerogen type I. Characteristics of kerogen and initial organic matter by pyrolytic parameters HI, Tmax refer to kerogen of type II-III, presumably with oil and gas formation and kerogen of type I with probable oil generation.
The hydrogen (HI) and oxygen (OI) indices of the studied samples, which allow us to determine the facies-genetic types of organic matter, indicate predominantly humus and less frequently humus-sapropelic origin, which allows us to conclude that the organic matter of the studied samples accumulated in moderately reducing conditions (kerogen types III and II) and coastal-marine environment (kerogen type I).
The organic matter of the studied samples is thermally mature according to Tmax, but the degree of maturity of the organic matter of cores from the depths of 1682.9 m (Daulov Formation) and 1896.54 m (Kumkol Formation) is lower. is estimated as low.
- По значениям Pr/Ph первичная нефтепродукция органического вещества Акшабулакского грабена формировалась в субокислительных условиях, а Аксайского горста и Бозингенского грабена – в окислительной среде.
In the initial organic matter of oils of the Aksai gorst, an increased content of gamma-ceran was noted, indicating a higher mineralization of the basin. The formation of the initial oil-forming substance of oils from Cretaceous sediments deposited, apparently, in marine, possibly shallow-water conditions was established.
- Carbon isotope composition (δ13C) of oils allowed to reveal genetic connection of the studied samples of Aryskum basin oils with organic matter of sapropelic type (kerogen type I and II), as well as their formation from organic matter of mixed humic – sapropelic type.
- The results of the presented geochemical studies indicate the possibility of predicting new zones of oil and gas accumulation in the sediments of the Lower and Middle Jurassic, occupying significant volumes of the sedimentary execution of grabens, which in turn allows expanding the idea of hydrocarbon potential of these fields in the section of the South Turgai basin.

Information for potential users
Underground mine workings at the mines of Karaganda coal basin are in unstable condition (by displacements of rocks of the roof, soil and sides), are maintained with significant material costs and labor intensity of works, which is due to the lack of justification for compliance of parameters of their fastening to the conditions of operation in the given mining and geological, technical and production conditions. Adoption of reasonable technological solutions for determining the parameters of fastening and effective operation is necessary geomechanical predictive evaluation of the deformed state of the rocks of the surrounding rock mass around the perimeter of the mine workings. Development and implementation of technology and means with justification of parameters of their fastening with regard to the stress-strain state of the host rocks will reduce labor costs and material costs in the operation of underground mine workings.
Today, one of the urgent directions of development of the coal industry is the development and testing of technological resource-saving methods and active means of fixing workings with stabilization of the rock mass to achieve a high technical and economic effect and improve the safety of mining operations.
Field of application
Mining, technique and technology of solid minerals extraction, implementation, support and repair of mining operations.
