FLOWSHEET ERECTION JUMPER INSULATION IN MINES

摘要

Usage: The invention relates to mining, and can be used to isolate the emergency sections of the existing mine workings. Objective: Increase the efficiency of extinguishing underground fires and safety of rescue operations at the emergency isolation of the mine sites by reducing the material costs for their production. SUMMARY: The system is further provided with a supply sleeve in an isolated space vapor nitrogen mixture, the sleeve 12 is connected with the side of the web to the flange of the tube 2 gas metering insulated space and to the second end of the sleeve is fixed to the outlet conduit remote control of the nitrogen complex, while it is connected to the second a tank of liquid nitrogen complex platform 16, with a flange with the flange of the gas metering tube of insulated space built into a line mixer 5 (sleeve 12) of liquid nitrogen, and the second suction sleeve formed from the additional vessel 4 a liquid refrigerant 114B2. The positive effect: The system design includes sufficiently reliable installation, created and improved in RosNIIGD that provide efficiency and safety of rescue works at liquidation of complex underground fires, while reducing material and labor costs for their production.
