AP13268891 “Development of effective technological schemes for the extraction of low-power deposits, ensuring a reduction in ore dilution, taking into account the geomechanical state of the rock mass” project manager Suimbaeva A.M.
Relevance
The relevance of the problem of creating technological schemes for optimizing the parameters of drilling and blasting operations (DBO), ensuring a reduction in ore dilution, taking into account the geomechanical state of the rock mass when breaking low-power ore bodies with highly fractured stable host rocks, has always been an important task in the mining industry. Optimization of DBO parameters based on a complex of geotechnical works can be the answer to the question of how to reduce costs and increase the efficiency of tunneling and clean-up operations while maintaining the high quality of the extracted useful component.
The aim of the project
The aim of the project is to conduct geotechnological studies on zoning of the deposit sites by rating of rock stability according to the geological strength index to develop optimal passports for drilling and blasting operations for the extraction of low-power ore bodies, depending on their capacity, ensuring a reduction in ore dilution.
Expected and achieved results
As a result of the project, optimal passports of drilling and blasting operations will be developed to reduce the dilution of ore during the breaking of low-power ore bodies based on the results of a complex of geotechnological (mine and laboratory) studies, including testing of rock samples for uniaxial compression, determining the quality of rocks RQD, surveying rock fracturing, accounting for lithology, waterlogging of rocks rocks and zoning of deposit sites according to the geological strength index (GSI). The adaptation of the most effectively used rating indicators of stability to the mining and geological conditions of the Zholymbet deposit and the zoning of the field sites according to the category of stability has been carried out.
A geotechnical block model has been created to assess the geomechanical state of the rock mass around the stope, taking into account the influence of the quality of blasting operations and the geological strength index.

Information for potential users
The passports of drilling and blasting operations will work for minimal seismic impact on the structured rock mass, which in turn will reduce the dilution of ore to the design indicator. Decrease in dilution of ore will reduce the volume of transportation of excess rock mass, stabilize the geomechanical state of the rock mass and improve the safety of mining operations.
Scope of application
Mining companies that develop fields of low-power ore deposits.
AP13268843 “Study of oil and gas potential of the pre-Mesozoic complex of the Aryskum trough of the South Torgai basin” project manager 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 a quasi-platform complex and disintegrated protrusions of the foundation. Currently, there are 52 oil and gas fields, the depletion of the initial recoverable reserves of which is quite high. Ingress of oil and gas of pre-Mesozoic formations up to industrial oil inflows allow us to draw conclusions about the presence of a certain potential of oil-and-gas-bearing capacity in them. In this regard, the determination of the oil origin and the forecast of the direction of hydrocarbon migration is relevant for the justification of deep drilling, in order to replenish the mineral resource base of the country.
The aim of the project
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 oil fields of the Aryskum trough of the South Torgai oil and gas basin.
Expected and achieved results
The results of the analysis of new data on the geochemistry of hydrocarbons in the South Torgai basin allowed us to draw the following conclusions:
- According to the results of pyrolytic core analysis, which allows to assess the generative potential of the oil-producing rock, it was found that the studied samples according to the ТОС concentration (from 0.47 to 1.41), as well as according to the parameter S2 (from 1.1 to 9 mg of HC/g of rock) have a potential from bad (poor) to good (rich) one,
- The determination of the type of kerogen according to the TOC dependency graph on the hydrocarbon potential showed that the vast majority of the studied samples belong to type II and type III kerogen, and only a sample from a depth of 1897.36 m, with maximum TOC and S2, is in the range of type I kerogen. Characteristics of kerogen and the initial organic matter according to pyrolytic parameters HI, Tmax are attributed to type II-III kerogen, presumably with the generation of oil and gas and type I kerogen with probable oil generation.
The hydrogen and oxygen indices HI and OI of the studied samples, which make it possible to determine the facies-genetic types of organic matter, indicate a predominantly humus origin and less often humus-sapropel, which allows us to conclude that the organic matter of the studied samples accumulated in moderately reducing conditions (type III and II kerogen) and coastal-marine environment (type I kerogen).
- According to the Pr/Ph value, the initial organic matter producing oil of the Akshabulak graben-syncline was formed under sub-oxidizing conditions, while the organic matter of the Aksai horst-anticline and the Bosingen graben-syncline was formed in an oxidizing environment.
An increased content of gammaceran, indicating a higher salinity of the basin area, was noted for the initial organic matter of the oils of the Aksai horst-anticline. The formation of the initial oil-producing substance of oils from Cretaceous sediments deposited, apparently in marine, possibly shallow water conditions, has been established.
- The isotopic composition of carbon of the δ13C oils allowed us to assume a genetic relationship of the studied samples of Aryskum deflection oils with sapropel-type organic matter (type I and II kerogen), as well as their formation from organic matter of mixed humus-sapropel type.
The results of the presented geochemical studies indicate the possibility of forecasting new zones of oil and gas accumulation in the sediments of the Lower and Middle Jurassic, which occupy significant volumes of sedimentary filling of grabens-synclines, which in turn allows expanding the representation of the hydrocarbon potential of these deposits in the context of the South Torgai basin.

Information for potential users
Underground mine workings at the mines of the Karaganda coal basin are in an unstable state (by displacements of the roof, soil and sides), are maintained with significant material costs and labor intensity of work, which follows from the lack of justification for the compliance of the parameters of their fastening with the operating conditions in the specified mining, geological, technical and production conditions. Making sound technological decisions to determine the parameters of the support and effective operation requires a geomechanical predictive assessment of the deformed state of the rocks of the enclosing rock mass around the perimeter of the mine workings. The development and implementation of technology and tools with the justification of the parameters of their fastening, taking into account the stress-strain state of the host rocks, will reduce labor costs and material costs during the operation of underground mine workings.
To date, one of the current directions of the coal industry development is the development and testing of technological resource-saving methods and active means of fixing workings with stabilization of the mountain range to achieve a high technical and economic effect and improve the safety of mining operations.
Scope of application
Coal mining industries with the extension of the obtained scientific and technical potential to underground mining enterprises.
AP13268798 “Development and industrial approbation of technological schemes for strengthening the weakened zone of rocks at the intersection of geological disturbance by preparatory mining” project manager Khalikova E.R.
Relevance
Due to the increasing depth of development of mineral deposits, mining and geological conditions are constantly deteriorating.
Increasing the stability of mine workings is one of the most important tasks in the underground development of mineral deposits.
The unsatisfactory condition of mine workings causes indirect financial and labor costs that are difficult to take into account, and also has a negative impact on a number of processes related to coal extraction technology (transport, ventilation, drainage, etc.). Therefore, the problem of the 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 of the development of the presented scientific direction 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 at the coal mines of the Karaganda basin. Therefore, pilot testing and commercialization of Kazakhstan’s technology to prevent collapses of the massif in the areas of increased displacement due to various kinds of violations of the occurrence of host rocks during underground workings based on numerical modeling of the stress-strain state of the rock mass is an urgent task in the field of mining in various mining conditions of preparation and schemes of mining coal seams.
