Development and On-site Practice of an Intelligent Continuous Long-distance Grouting System
A smart continuous long-distance grouting system has been developed to address the issues of low efficiency,poor safety,uneven mixing ratio,and inability to timely supplement and adjust slurry leakage in traditional grouting systems for coal seam roof reinforcement.The system mainly includes a slurry making system,pressure drop system,pipeline system,PLC control system,etc.The aim is to achieve automatic feeding,precise control of slurry mixing ratio,real-time monitoring of grouting parameters,and improvement of grouting efficiency.The system has been tested in the laboratory and on-site industrial trials.On-site applications showed that the system could achieve precise capture and output of instructions,ensuring collaborative operation of various associated devices,timely response,and precise execution.The ratio accuracy of the slurry is high,the overall reliability of the system is strong,the grouting amount is basically consistent with the theoretical value,and the efficiency is high,safe and reliable.
