Method for preparing cemented filling material by using chlorinated lime to excite coal gasification slag
The invention relates to a method for preparing a cemented filling material by using chloridized lime to excite coal gasification slag, which comprises the following steps: collecting solid residues after coal gasification, sorting and cleaning to remove dust and impurities of the coal gasification slag, then airing, and grinding by using a planetary ball mill to form ultrafine powder after airing; the method comprises the following steps: collecting coal gangue, crushing the coal gangue until the particle size is less than 15mm, and screening the crushed coal gangue by using a vibrating screen to obtain fine aggregate, medium aggregate and coarse aggregate; respectively adding different doping amounts of chloridized lime into the prepared superfine powder of the coal gasification slag, and uniformly stirring; and uniformly stirring cement, the fine aggregate, the medium aggregate, the coarse aggregate and the superfine powder of the coal gasification slag containing the exciting agent, filling the filling material slurry into a mold, and curing in a curing room.
本发明涉及一种利用氯石灰激发煤气化渣制备胶结充填材料的方法,包括以下步骤:收集煤气化后的固体残渣,分拣清理去除煤气化渣的尘土与杂质,然后进行晾晒,晒干后利用行星式球磨机研磨形成超细粉体;收集煤矸石,对其进行破碎使其颗粒粒径小于15mm,用振动筛将破碎煤矸石进行筛分,得到细骨料、中骨料和粗骨料;将制得的煤气化渣超细粉体中分别加入不同掺量氯石灰并搅拌均匀;将水泥与上述制得的细骨料、中骨料、粗骨料及含有激发剂的煤气化渣超细粉体均匀搅拌,将充填材料料浆装入摸具中,在养护室养护。
