Product description
Parameters

The essence of nitrogen fire control in mine is to inject a certain amount of nitrogen into the oxidation zone of goaf or fire zone to reduce its oxygen content to less than 5%,so as to prevent fire control and suppress gas explosion.Compared with other fire prevention methods in mines,nitrogen fire prevention technology is better than traditional grouting fire prevention technology:nitrogen injection technology is fast and rapid.Product nitrogen low temperature,nitrogen can quickly permeate into the goaf oxidation zone or the corners of the fire zone.And grouting technology,because the slurry in the goaf oxidation zone or the flow of the fire area is affected by uneven floor,roof riser not equal factors,will form a"flow groove",thus can not evenly and comprehensively cover the surface of"media",failed to play a real role in"isolation"of oxygen,prevent coal oxidation spontaneous combustion.Therefore,nitrogen fire-fighting technology has its better fire-fighting effect.
