Abstract
Спосіб боротьби з вибухами вугільного пилу та метану складається з відбору води з шахтного водогону, збільшення тиску відібраної води водяним насосом, подачі цієї води в магістраль зрошення видобувного комбайна і використання води шляхом її розпилення форсунками безпосередньо в місці руйнування вугілля виконавчим органом видобувного комбайна. Перед подачею в насосну установку воду насичують під тиском інертним газом, наприклад азотом або вуглекислим газом, після чого воду, насичену інертним газом, розпилюють в конусі форсунки на виході з неї під заданим тілесним кутом. Пляму від конуса розпилення газоводяної суміші спрямовують як на різець робочого органу видобувного комбайна, так і на поверхню забою позаду різця.The method of combating explosions of coal dust and methane consists of extracting water from the mine water pipe, increasing the pressure of the extracted water with a water pump, feeding this water into the irrigation main of the mining combine and using the water by spraying it with nozzles directly at the place of coal destruction by the executive body of the mining combine. Before being fed to the pumping unit, the water is saturated under pressure with an inert gas, such as nitrogen or carbon dioxide, after which the water saturated with the inert gas is sprayed into the cone of the nozzle at the exit from it at a given body angle. The spot from the spray cone of the gas-water mixture is directed both to the cutter of the working body of the mining combine and to the surface of the face behind the cutter.
