山东能源柴里煤矿打造“三位一体”掘进新样板

Core Viewpoint - Shandong Energy Zhaokang Group's Chaili Coal Mine has successfully transformed its operations from a rough "experience management" approach to a refined "standard-led" model, creating a standardized engineering example for "safety, quality, and efficient excavation" [1] Group 1 - The 273 down 02 transportation lane has undergone significant improvements due to standardization, including the replacement of outdated equipment with KCG-500D dry dust collectors and 45KW×2 variable frequency fans, resulting in sufficient airflow and a substantial reduction in dust concentration [2] - Strict implementation of the "five zones and one material" system for roof management has made accident risks controllable, with precise data standards and testing methods for bolt and cable pre-tensioning and spacing [2] - The introduction of laser alignment tools for precise construction has achieved the goal of "one-time excavation, no repairs needed," while a comprehensive control process for support quality ensures that every bolt undergoes rigorous testing [2] Group 2 - The production organization has been optimized through standardized processes such as three-shift production, overhead rail systems, and "one-stop" material delivery, significantly reducing workflow waste and achieving a daily progress of 12 meters with six excavations per shift [2] - The mine has begun to see the benefits of intelligent construction, with advanced equipment like the EBZ-320 comprehensive excavation machine and lithium battery monorails enabling remote control of cutting and belt transport [2] - The cultural shift towards standardization has led to a self-driven approach among employees, fostering a cycle of problem identification, cause analysis, measure formulation, and continuous improvement [3]
