Core Viewpoint - The article discusses the innovative "one belt per tunnel" transportation model implemented by Shanxi Huayang Group to enhance safety and efficiency in coal mining operations, addressing traditional transportation challenges in the industry [2][3]. Group 1: Transportation Model Innovation - The traditional model required installing a belt conveyor every kilometer, leading to decreased efficiency and increased labor costs due to the need for additional personnel [3]. - The new model allows for a single long-distance belt conveyor to replace multiple traditional units, significantly reducing power consumption by 290 kilowatts and achieving a 15.34% reduction in electricity usage [3]. - The transportation capacity increased from 1,500 tons per hour to 2,500 tons per hour, while also lowering the impact load on equipment and reducing the number of required personnel by three, saving approximately 540,000 yuan annually [3]. Group 2: Implementation and Results - In 2023, Huayang Group installed 23 long-distance belt conveyors, achieving a 100% completion rate on schedule, resulting in a total labor cost reduction of about 12.42 million yuan [4]. - All 18 coal mining working faces and 68 tunneling working faces have adopted the "one belt" transportation model, achieving full coverage [4]. Group 3: Challenges and Solutions - The implementation faced challenges such as complex geological conditions and varying slopes, which could lead to issues like belt misalignment [5]. - To address these challenges, the company collaborated across departments to enhance equipment adaptability, including the installation of anti-misalignment rollers and protective measures for stable operation [6]. - The company has customized solutions for different mining conditions, ensuring the effective application of the "one belt per tunnel" model across various mining sites [6].
