The West Kazakhstan region is rich in oil and gas reserves due to its historical geological development factors. The purpose of the study is to study the geographical distribution of gas and oil fields in the West Kazakhstan region. The article provides locations, location, geological development, geological age, depth of occurrence, occupied territory, reserves and share in the development of the country’s economy. The description of about twenty oil and gas fields in the region is given. The largest of them are the Karachaganak and Chinarevskoye fields. In the course of the article, based on the study of factual material, an attempt was made to provide an economic justification for the use of all types of material raw materials for the development of agriculture in the region, taking into account the integrated use of energy and mineral resources, their effectiveness.

ОПРЕДЕЛЕНИЕ УСТОЙЧИВОГО СОСТОЯНИЯ ТЕХНОГЕННЫХ ОБНАЖЕНИЙ ПРИ ОТРАБОТКЕ НАКЛОННЫХ РУДНЫХ ЗАЛЕЖЕЙ КАМЕРНО-СТОЛБОВОЙ СИСТЕМОЙ РАЗРАБОТКИ

Статья посвящена разработке ресурсосберегающих технологий отработки наклонных залежей с применением камерно-столбовой системы разработки. В статье установлены закономерности изменения напряженно-деформированного состояния массива горных пород в зависимости от технологических параметров очистного забоя для обоснования применения камерно-столбовой системы разработки при отработке наклонных рудных залежей. Изучение изменения напряженно-деформированного состояния массива горных пород при отработке наклонных залежей камерно-столбовой системой разработки проводилось методом конечных элементов. Получены закономерности изменения напряженно-деформированного состояния (НДС) вокруг очистной выработки.

The article explores the use of degassing wells for capturing and utilizing methane at the Kirovskaya mine. The study presents results from measurements of gas pressure and flow rate at the vacuum pump station. An analysis of the parameters of the methane-air mixture and methane concentration in the mined-out space confirms the accuracy of the gas collector volume calculations. Factors affecting methane concentration, such as the volume of voids and fractures, were investigated, and methods for managing gas emission were examined. Methane concentrations in the Karaganda Basin mines can reach 90-95% after ventilation ceases. Methane flow rates through degassing wells ranged from 4.9 to 1380.6 thousand m³, with a total capture of 7547.1 thousand m³ over 21 months. The results highlight the importance of degassing wells for the safe management of gas emission.
