Abstract：China possesses abundant coal reserves under complex geological conditions,road-way driving is the forerunner and premise of coal mining.Achieving rapid and intelligent driv-ing in coal mine roadways under such circumstances remains a global challenge.Current rapid and intelligent driving technologies and equipment for complex-condition coal mines face three primary challenges.The first challenge is the cumbersome support processes with heavy reli-ance on manual labor.The second challenge is the insufficient equipment integration,coordi-nation,and intelligence.The third challenge is the inadequate real-time monitoring technolo-gies for rock-equipment-environment interactions.To address the issues,particularly the multi-step support processes,excessive manual intervention in critical operations,and difficul-ties in achieving rapid intelligent support,it is necessary to develop intelligent identification methods for roof stabilization of heading faces under complex geological conditions.Research-ers are necessary to establish time-dependent surrounding rock control theories for heading faces in complex roadways,and reveal surrounding rock control mechanisms with integrated drilling and anchoring bolts-spray layer under complex conditions.Moreover,integrating drill-ing and anchoring bolts,along with corresponding construction equipment,and automating the spraying of support materials with corresponding construction equipment under complex condi-tions are also should be developed.In response to equipment-related challenges including poor collaborative control,low system integration,and inadequate intelligence,it is necessary to study the multi-process parallel collaborative intelligent control technologies for driving equip-ments;rapid and intelligent driving equipment combining driving-support-anchor-transport zonal parallel collaboration function,and rapid and intelligent driving equipment combining driving-support-anchor integrated centralized coordination function.Regarding the deficiency in real-time and dynamic monitoring of rock-equipment-environment interactions and intelligent operation/maintenance capabilities,it is need to develop real-time strata pressure monitoring technologies for complex-condition roadways;and big-data-driven intelligent driving equipment operation/maintenance technologies.Through breakthroughs in three key theoretical areas,the development of five core technologies,and the creation of complete equipment systems,this research achieves:rapid and intelligent support at heading faces,enhanced equipment in-telligence levels,and intelligent operation/maintenance capabilities.Ultimately,it establishes a comprehensive theoretical-technical-equipment framework for rapid and intelligent driving in complex-condition coal mines,providing robust technical support for China's safe and efficient intelligent coal mining initiatives.
