本设计提出了一种利用煤矸石直接填充采空巷道的煤矿专用矸石回填机械设备,以解决开采沉陷对地面建筑物以及工农业生产的影响问题与煤矸石升井后在地面堆放对环境产生危害的问题,此设备还可以适应采煤巷道的矸石充填以及对 “三下”(水下、道路下、建筑物下)压煤开采后填充这一煤炭行业面临的共性难题。
自移式矸石回填机由切顶支撑,机座,转向工作台,抛射带式输送机以及可伸缩带式输送机五大部件组成,用液压作为为动力源,以液压缸为动力执行元件,来实现机械的移动和调偏,实现了自动化控制,使得矸石回填效率大大提高,应用了自行设计的万向底座充分保证了支撑腿对各种角度巷道的适应性,切实保证了支撑腿的牢靠。此外,本矸石回填机行走底盘大大简化,省去了减速器等一系列的辅助部件,减少了成本,且提高了回填机的平稳性和机动性。
矸石回填技术的推广及矸石回填机的研制和不断改进,不仅消除了煤矸石堆放对环境的影响,而先采掘后填充,降低了采煤对地层岩石的破坏程度,减缓了开采塌陷对地面建筑物以及工农业带来的危害,必将会给我国“三下”煤层的开采带来新的途径,此举将产生极为可观的经济效益、环境效益和社会效益。

he design advances an equipment of direct use of coal gangue-filled air roadway in a coal mine waste rock backfill for machinery , to solve the problem of mining subsidence on the surface buildings and the impact of industrial and agricultural production and the harm to the environment issue that gangue on the ground well after piling up . This equipment can also adapt to the coal mining roadway and filling the "three" (underwater, roads, buildings under), the common problems of pressuring after the filling which the coal industry faces.
This equipment is made up of five major components, it supports from all the top, and the other for major components are the frame, to table, Projectile and the retractable belt conveyor .As for the use of hydraulic power source to power hydraulic cylinders for the implementation of components, machinery to achieve the movement and transfer partial, and the automatic control, makes waste backfill efficiency greatly improved. In addition, the waste rock backfill walking chassis greatly simplified, eliminating the reducer and a series of auxiliary components, reducing costs and improving the backfill for the smooth and mobility. T
Therefore, how to treat huge stocks of gangue is an urgent task faced coal mines. Treatment difficulties will be solved completely if gangue is used to fill underground emptied stopes as aggregate. At the same time, recovery rate of coal can be improved, safety pillar can be extracted, movement of layer can be restrained and ground surface can be protected. Suncun Coal Mine (SCM)
