Konlarda oltin tarkibli rudalarni qazib olish jarayonida konlarning shamollatish tarmog‘idagi havo miqdori kon lahimlari uzunligining oshishi va konning chuqurlashishiga mutanosib ravishda ortadi. Maqolada konga havo oqimini boshqarish, konning tashqi va ichki yo‘qotishlarini kamaytirish uchun havo pardalaridan foydalanish va aerodinamik qarshilik masalalari ko‘rib chiqilgan. Shuningdek, murakkab shamollatish tizimlariga ega shaxtalarning shamollatish samaradorligini oshirish uchun bosh ventilyator qurilmasi va shamollatish kanalida tashqi havo yo‘qotilishini kamaytirish uchun optimal shamollatish sxemasi hamda shamollatish parametrlari bo‘lgan havo sarfi , havo oqimi tezligi va bosimi o‘zgarishi ko‘rsatkichlarining optimal qiymatlarini belgilash orqali shamollatish tarmog‘ida havo oqimini samarali boshqarish va taqsimlash yo‘llari keltirilgan.

При добыче золотосодержащих руд в шахтах количество воздуха в вентиляционной сети рудников увеличивается пропорционально увеличению длины горных выработок и углублению шахт. В статье рассмотрены вопросы управления притоком воздуха в шахту, использования воздушных завес для снижения внешних и внутренних потерь шахты и аэродинамического сопротивления. Также в целях повышения эффективности вентиляции шахт со сложными системами вентиляции, снижения потерь наружного воздуха в главном вентиляторном устройстве и вентиляционном канале, определения оптимальной схемы вентиляции и оптимальных значений расхода воздуха, показателей изменения скорости потока и давления с параметрами вентиляции, представлены способы эффективного управления и распределения воздушного потока в вентиляционной сети.
On the extraction of gold-bearing ores in mines, the amount of air in the ventilation network of mines increases in proportion to increases in the length of excavations and deepening of the mines. The article deals with issues of managing the air flows into mines, the use of air curtains to reduce external and internal losses to the mine, and aerodynamic resistance. The work describes the use of the main fan and an optimal ventilation scheme in order to increase the efficiency of ventilation in mines with complex ventilation systems, with the view to reducing outdoor air losses in the ventilation duct and ventilation network by determining the optimal values for airflow, air flow rates, and pressure changes with ventilation parameters to ensure ways of effective control and distribution of the airflow.
