科技绘就青山新卷 创新赋能生态振兴

Core Viewpoint - The transformation of the Majiliang Mine represents a model for high-quality development in China's energy sector, emphasizing ecological restoration and technological innovation to achieve sustainable mining practices [3][4]. Group 1: Environmental Improvements - The Majiliang Mine has implemented comprehensive management of water, air, and solid waste, leading to continuous environmental quality improvement [4]. - The mine has replaced four coal-fired boilers with modular gas boilers and smart control systems, resulting in a 50% reduction in heating response time and a 15% increase in thermal efficiency, which translates to a reduction of 3,400 tons of standard coal consumption and over 8,900 tons of CO2 emissions annually [4]. - A water treatment facility with an 8,000 cubic meter daily capacity has been established, utilizing a three-step process to recycle mine water, saving millions of tons of new water resources each year [6]. - The mine has adopted an innovative approach to solid waste management, planting over 30,000 trees and increasing vegetation coverage by 40%, effectively mitigating dust issues from historical waste piles [6]. Group 2: Technological Innovations - The mine has embraced digital transformation, utilizing 5G technology to enhance the precision of coal mining operations, significantly improving coal recovery rates and operational efficiency [8]. - The introduction of a "zero-emission" transportation strategy, including the use of silent, battery-powered vehicles, is projected to reduce carbon emissions by 150 tons annually [8]. - The intelligent coal preparation plant has improved production efficiency and safety, reducing labor costs by 720,000 yuan and increasing the amount of washed coal by 20,000 tons [9]. Group 3: Employee Well-being and Community Engagement - Infrastructure improvements have led to a 95% satisfaction rate among employees, with enhanced facilities for health and recreation [11]. - The mine promotes green practices among employees, with initiatives like tree planting and paperless operations, contributing to significant reductions in resource consumption [11]. - The mine's management emphasizes that the coal industry can be a proponent of ecological development, aiming for harmony between mining operations and environmental sustainability [11].
