浅析井下煤矸分离与综合机械化固体充填采煤技术

Brief Analysis of Underground Coal Gangue Separation and Comprehensive Mechanized Solid Filling Coal Mining Technology

煤矿进行三下压煤开采过程中,为确保矿区环境不受破坏,采用煤矸井下分离与综合机械化固体充填采煤技术进行开采施工。分析了综合机械化固体充填技术,提出了采用井下煤矸分离及矸石充填采煤,并结合具体案例讨论了井下煤矸分离和综合机械化固体充填采煤技术的应用。该技术的应用能实现控制地表沉陷及绿色开采、矸石减排的目的。

To ensure the environment of the mining area is not damaged in the process of coal mining for coal under railway, water and buildings, mining and construction were carried out by underground coal gangue separation and comprehensive mechanized solid filling coal mining technology. This paper analyzed the comprehensive mechanized solid filling technology and put forward the method of coal mining by adopting underground coal gangue separation and gangue filling. Combined with specific cases, this paper discussed the application of underground coal gangue separation and comprehensive mechanized solid filling coal mining technology. The application of this technology can control the surface subsidence and achieve the green mining and gangue emission reduction.
