Yer osti konlarining gorizontlari chuqurlashishi natijasida qazib olish sharoitlarining murakkablashib borishi bilan lahimlarni shamollatish tarmog‘idagi havo miqdori ham mutanosib ravishda ortadi. Maqolada havoni taqsimlash, havo miqdori yo‘qotishlari va aerodinamik qarshiliklarni kamaytirish uchun havo oqimi to‘siqlari, havo ejektorlari, havo klapanlaridan foydalanish masalalari ko‘rib chiqilgan. Shuningdek, kon lahimlarini shamollatishda murakkab kon-texnologik sharoitlarda shamollatish usullari, shamollatishda havo oqimi tezligi, bosimi, lahim kesim yuzasiga bog‘liq holda havo tezligi va bosimi o‘zgarishi kabi ko‘rsatkichlarning optimal qiymatlariga erishish orqali shamollatish tarmog‘ida havoni taqsimlash yo‘llari keltirilgan.

С углублением горизонтов подземных выработок пропорционально увеличивается и количество воздуха в вентиляционной сети припоев, наряду с усложнением горных условий. В статье рассматривается использование барьеров воздушного потока, воздушных эжекторов и воздушных клапанов для уменьшения распределения воздуха, потери объема воздуха и аэродинамического сопротивления. Кроме того, изучены способы вентиляции в сложных горно-технологических условиях в шахтных припоях, способы распределения воздуха в вентиляционной сети за счет достижения оптимальных значений таких параметров, как скорость воздушного потока, давление, изменение скорости воздуха и давления в зависимости от поверхности участка припоя.

English

The article reviews the use of air flow barriers, air ejectors and air valves for reducing air volume losses and aerodynamic drag. Increased of scope of underground works causes proportional increase of the amount of air in the ventilation network of solders along with complication of mountain conditions. It also describes ventilation methods in difficult mining and technological conditions when ventilating mine solders, the distribution of air flows in the ventilation network by achieving optimal values of such indicators as air flow rate, pressure, change in air speed and pressure depending on the sectional surface of the solder.
