Automatic control of the atmosphere and localization of explosion and fire in mines

摘要

The utility model relates to mining, and is designed to prevent the emergence and spread of explosions metanopylevozdushnoy mixture in mine workings of coal mines, hazardous gas methane and coal dust.; The system comprises an underground part of the automatic control parameters metanopylegazovoy mixture and tracking ground station controller mountain of the atmosphere in mines. Underground part includes a number of sensors fixing the concentrations of the gas mixture to the lower explosive limit of: methane sensor, carbon monoxide, a dust sensor, a temperature sensor, which are connected to the controller. When fixing any of the lower explosive limit of the mixture in a pre-crash sensor controller step includes canceler control portion explosions and fire - water curtain connected to the fire water network. Simultaneously, the controller includes alarm device. Apparatus water curtain consists of a series (or rows) of nozzles arranged along the perimeter of excavation. For water spray dampener further installed in front of the blast wave baffle. Underground controller is connected to the ground point tracking, designed as a controller with a display.; EFFECT: increased efficiency and reliability of the system. 1N. PI 6 z.p.p. f-ly. 1 yl.
