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 gradually promoted the filling technology of coal mined-out area. After the mining face is advanced, the back filling is to fill the slurry in the goaf and reduce the sinking of the ground. Face filling for the support and filler filling, there is no mature technology and equipment, is now used than the original single hydraulic props and baffle seal, move forward by manual means. In response to this phenomenon, the need to design automatic sealing and centralized control support equipment, between the frame with a special plastic block seal, the top plate with adhesive tape and tape automatically adjust the seal, the device has a support, sealing, automatic Promote other functions.
