FIELD: mining.
SUBSTANCE: present invention relates to supply of fluid medium to longwall development system. Longwall excavating combines system comprises a mining combine made with possibility of movement along the ore mine face, note here that said mining machine comprises excavating machine body, cutting drum engaged with said drum body and nozzle arranged on cutting drum. First electronic controller, comprising a first processor and a first memory and configured to measure a performance parameter of the longwall extraction machine operation, wherein the productivity parameter corresponds to the location of the excavating machine along the ore face and indicates an approximate amount of ore that is mined during a specific period of time. Fluid feed system comprises flow control device in fluid communication with nozzle and fluid medium source. Second electronic controller comprising a second processor and a second memory and connected to the flow control device, wherein the electronic controller is configured to receive the performance parameter indicator, determine the model fluid flow based on the performance parameter indicator, and setting the operating parameter of the flow control device based on the model fluid flow, and activating the flow control device with the predetermined operating parameter.
EFFECT: technical result consists in improvement of flow control based on model flow of fluid medium.
