承压下膏体充填支护与密封技术研究

Study on Support of Paste Filling under Pressure and Sealing Technology

国内已经逐步推广煤矿采空区的充填技术。采面推进后,后部充填是在采空区灌注浆料,减少地面下沉。针对充填时的工作面支护和填充料的密封,国内暂无成熟技术和设备,现在用的是较原始的单体液压支柱和挡板密封,前移采用人工推移方式。针对此种现象,需设计出自动密封和集控操纵的支护设备,架与架之间采用特殊的胶块密封,顶板采用胶块和胶带自动调节密封,本设备具有支护、密封、自动推进等功能。

China has been gradually extend the filling technique of current coal mining area. Face forward, the back of the gob filling perfusion in size, reducing ground subsidence. As to the workplace supporting and sealing filler for filling, domestic has no mature technology and equipment, now using a more primitive hydraulic prop and baffle seals,pulling forwards by humans.In such cases, need to design a self-sealing and retaining centralized control manipulation equipment. Between frame and frame use special rubber seal, roof use plastic blocks and tape adjustment automatically to scale. This equipment has supporting, sealing and self-propelled functions and so on.
