Application of remote water injection system with intelligent grading for fire areas at STM32 coalfield
The traditional water injection method is inadequate and costs huge engineering workload with low efficiency,which results in plenty of water waste.To overcome the obstacles,we introduced remote intelligent water injection technology to coalfield fire areas.This method integrated temperature parameter acquisition module,circuit control module and flow control valve into the intelligent injection distributor that is kept on the surface.Based on wireless communication technology and automatic adjustment algorithm,an intelligent injection process including intelligent injection distributor,intelligent measurement control and charging integrated instrument and surface communication control host was developed.The monitor system was developed to adjust the operation time of water injection and temperature measurement process,hence water injection flow of 2 L/s,1 L/s and 0.5 L/s was designed.In-situ test at Sandaoba coalfield fire area in Xinjiang Province showed that the intelligent grading water injection technology can provide technical support for intelligent fire extinguishing in coal fire areas.
