Preparation method of coal-based solid waste filling paste and filling system
The invention discloses a preparation method of coal-based solid waste filling paste and a filling system, and relates to the technical field of paste filling. The preparation method comprises the following steps: screening and classifying coal-based solid waste materials according to fly ash, gasification slag, furnace bottom slag and desulfurized gypsum; respectively putting various waste solidmaterials such as fly ash, gasification slag, furnace bottom slag and desulfurized gypsum into a vibrating screen for screening; carrying out primary stirring on the additive and water, and then carrying out secondary stirring on the additive, fly ash, gasification slag, furnace bottom slag and desulfurized gypsum fine particles; crushing coal gangue produced by a working face by a roller crusherunderground, putting crushed fine particles into a thickener, and mixing with a flocculating agent to form high-concentration slag slurry; conveying the coal-based solid waste paste prepared by mixingto the underground through a ground pump plant, and carrying out three-stage stirring on the coal-based solid waste paste and coal gangue fine particles; and conveying the prepared coal-based solid waste paste to an underground storage chamber and then conveying to a filling working face to complete the filling work of the coal-based solid waste paste.
本发明公开一种煤基固废充填膏体的制备方法及充填系统，涉及膏体充填技术领域，包括如下步骤：将煤基固废材料依据粉煤灰、气化渣、炉底渣、脱硫石膏进行筛选分类；将粉煤灰、气化渣、炉底渣及脱硫石膏各类废固材料分别投入振动筛进行筛选；将添加剂与水进行一级搅拌，再与粉煤灰、气化渣、炉底渣及脱硫石膏细颗粒进行二级搅拌；工作面产出的煤矸石在井下利用辊式破碎机进行破碎，破碎后的较细颗粒再投入浓密机中，与絮凝剂进行混合，形成高浓度渣浆；混合制备的煤基固废膏体经由地面泵厂输送至井下，再与煤矸石细颗粒进行三级搅拌；制备好的煤基固废膏体运至井下储存室，再送至充填工作面，完成煤基固废膏体充填工作。
