Core Viewpoint - The company has successfully implemented a new technology for coal mining that addresses the challenges posed by complex geological conditions, particularly in areas with significant surface structures and resources that are difficult to access. This innovation is expected to enhance the efficiency and sustainability of coal extraction while minimizing environmental impact [1][2][3]. Group 1: Technology Implementation - The company has introduced the overburden layer grouting filling technology, which stabilizes subsurface structures and allows for the recovery of previously inaccessible coal resources [1]. - A comprehensive control model for surface subsidence has been developed, which includes four zones: conventional, transition, grouting, and control, enabling precise management of subsidence in complex terrains [2]. - The company has successfully recovered 475,000 tons of coal and managed to treat 300,000 tons of mine wastewater while keeping surface damage within national standards [2]. Group 2: Innovation and Efficiency - The company has created a full-process intelligent monitoring system for grouting, ensuring that every drop of grouting liquid reaches its target, with surface subsidence controlled to millimeter levels [3]. - Continuous upgrades to the grouting technology have led to a complete set of processes suitable for the geological conditions of the mine, addressing multiple engineering challenges [3]. - The company has released approximately 4.7 million tons of overburden coal and processed over 3 million tons of industrial solid waste, generating profits of about 1.73 billion yuan [3]. Group 3: Future Directions - The company is researching the integration of grouting technology with the 110 method, aiming for a more efficient resource recovery process [3]. - The company emphasizes a commitment to innovation-driven development and the deep integration of new technologies with green development, paving the way for high-quality growth [3].
