Innovative Practices and Value Analysis for Improving Effective Production Time in Tunneling Operations
Abstract：To address the industry pain point of insufficient effective production time in coal mine tunneling operations, this study takes the 23303 transportation alley of Ordos Zhuanglongwan Coal Co., Ltd. (hereinafter referred to as Zhuanglongwan Coal Mine) as the research object. By integrating a process diagnosis model with lean management methods, a three-dimensional solution combining 'technological innovation - management optimization - data-driven' is proposed. Through the development of an intelligent self-moving tail machine platform (integrated with material racks, cable troughs, and unloading hoppers), optimization of dynamic transformer layout, and the innovative '2 steps 1 handover + 3 days 1 maintenance' production organization model, the effective production time of tunneling was increased by 34.3% (from 411.5 h to 554.84 h), with a monthly advancement of 1,437 m (59% over plan), achieving a comprehensive benefit of 7.64 million yuan. The research results provide a replicable technical path and management model for the construction of smart mines.
