随着我国煤炭持续高强度开发，开采条件逐渐恶化，传统开采方法带来一系列资源、安全与环境问题。基于“岩层低损伤”，“无煤柱开采”和“固废零排放”的思路，提出了以煤矿井下采区内就近分选矸石为主形成的固体废弃物充填带取代区段煤柱的“短充长采”科学开采构想及其技术原理。探索了“采-选-充-留”关键技术路径，统筹研究解决遗留煤柱的资源浪费、固废排放的环境污染、传统开采的技术瓶颈和深部开采的安全风险。建立了“短充长采” 固体废弃物充填带能量缓释理论和低损伤岩层控制理论。阐述了5项关键技术：“短充长采”系统设计方法，井下智能干法轻量模块化分选系统，自成巷前进高效采充技术与装备，沿充填带留巷技术与装备，“短充长采”系统集成控制技术。现场应用结果表明：“短充长采”科学开采模式在葫芦素煤矿和刘庄煤矿井下矸石直接充填能力分别达到200万 t/a 和100万 t/a，利用有限的的固废资源集成解决了煤炭开采的资源、安全和环保问题，可以实现井下无煤柱、地面固废零排放。该模式创新了绿色开采新理论、新技术、新方法，构建了我国新型绿色开采的科学开采体系。

With the continuous high-intensity development of coal mine in China, mining conditions have gradually deteriorated, and traditional mining methods have brought about a series of resources, safety and environmental problems. Based on the ideas of “low damage of rock strata”, “mining without coal pillars” and “zero solid waste discharge”, the scientific conception of “short-wall filling & long-wall mining” and its technical principle to replace the section coal pillars with solid waste filling belt formed by nearby sorted gangue in underground coal mining area are put forward. Key technologies of“picking-selecting-filling-retaining”have been explored to deal with the problem of the resources waste of remaining coal pillars, environmental pollution caused by solid waste discharge, and technical bottlenecks of traditional mining and safety risk of deep mining as a whole. The theory of slow energy release and the theory of low damage rock control on solid waste filling belt are put forward. Five key technologies are described: “short-wall filling and long-wall mining" system design method, underground intelligent dry-weight light-weight modular sorting system, self-contained and high-efficiency mining technology and equipment,technology and equipment for retaining roadway along filling belt, and the integrated control technology of “short-wall filling & long-wall mining” system.The field application results show that the “small-charge long mining” scientific mining model has a underground gangue direct filling capacity of 2 million t/a and 1 million t/a in the Hulusu Coal Mine and Liuzhuang Coal Mine respectively, and the coal mining is solved by the limited solid waste resource integration. The resources, safety and environmental protection issues can achieve no coal-pillar mining in underground and zero solid waste on the ground. This model has innovated new theories, new technologies and new methods of green mining, and constructed a scientific mining system for new green mining in China.
