Abstract

The invention discloses a small size simulation experiment table for underground coal mine exogenous fire. The small size simulation experiment table comprises a tunnel and an auxiliary measurement and control system, wherein the auxiliary measurement and control system comprises a flue gas temperature collection system, a heat loss measurement system, a flue gas measurement alarm system, a mechanical ventilation and flue gas exhaust system and a flue gas flow field display system; the flue gas temperature collection system comprises a distributed fiber temperature measurement circuit mounted in the tunnel and a thermal infrared imager mounted at the opening of one end of a simulated tunnel; the heat loss measurement system comprises a heat flux sensor mounted in the tunnel; the flue gas measurement alarm system comprises a flue gas analyser measurement point and an ion flue gas sensing detection alarm which are mounted in the tunnel. The small size simulation experiment table can simulate the situation, flue gas components, flue gas flow rule, temperature field variation rule, poisonous and pernicious gas concentration variation rule and heat loss during fuel combustion in case of fire in a laboratory, and develops a suitable coal mine tunnel detection and control system.

Description

technical field [0001] The invention relates to the technical field of fire safety, in particular to a small-scale simulation experiment platform for external fires in coal mines. Background technique [0002] Coal is the main energy source in our country, and belt transportation is one of the main coal transportation methods in mines, and it is a strong guarantee for efficient production of coal mines. Extrinsic fires in coal mines refer to fires caused by external heat sources. The main causes of fires are blasting, electric sparks, electric arcs, gas and coal dust explosions, and mechanical friction. In the fire caused outside the mine roadway, the control of smoke, fire fighting, and temperature control are the focus of people's attention, because many toxic and harmful gases such as gas will be produced in the coal mine roadway, and the high temperature will easily cause the gas to explode and cause more serious disasters. For the smoke composition, flue gas flow law, ...
