The utility model provides a backfilling support device for filling mining, which comprises a bolt, one end of the bolt is inserted into the roof of the ore body in the mining area, the other end is provided with a sleeve, on which a connecting piece is formed; a filling material is filled in the plane of the mining area; a supporting pile, which is connected and fixed with the bolt through the connecting piece on the sleeve, and one end is close to the mining The other end of the roof of the ore body in the area is immersed in the filler. The anchor bolt in the roof of the ore body in the mining area is connected with the pre prepared concrete support pile through the casing. After the installation of the support pile is completed, the backfilling of the goaf is carried out. When the support pile is immersed in the filler to the preset depth, the backfilling is stopped, so as to ensure the spacing between the surface of the filler and the roof of the ore body in the mining area, and the backfilling is carried out. After solidification, the ground pressure of the roof is transmitted to the filling material through the support pile, which plays the role of supporting the roof. At the same time, the space between the filling material and the roof of the ore body is the compensation space for the next layered blasting.

充填采矿接顶回填支撑装置
本技术涉及采矿回采回填
,具体地说,涉及一种充填采矿接顶回填支撑装置。
技术介绍
充填采矿法是指伴随落矿、运搬及其他作业的同时,用充填料充填采空区的采矿方法,其目的是支护采空区两帮岩石,并为继续进行上面分层回采造成立足的底板。而在回采过程中,通常采用间隔回采,即于一期矿房回采接触后进行接顶充填,用充填体支撑上部顶板,之后再进行二期矿房的开采。现有技术下的接顶充填,充填后形成的充填体距空区顶板的高度在0.7米左右,从而使得在二期矿房开采时因顶板跨度大,暴露面积剧增,继而致使顶板垮塌风险增高。另一方面,针对上述问题,若接顶充填的接顶率增高,则又会造成下一分层回采时爆破补偿小,又会降低回采作业效率。因此,接顶率过高或过低都会对回采作业或者以及施工安全造成不同程度的影响。有鉴于此,应当对现有技术进行改进,以解决现有技术中存在的上述技术问题。
