High-solid-phase strong-stability goaf solid waste filling slurry, preparation system and preparation method
The invention discloses high-solid-phase strong-stability goaf solid waste filling slurry, a preparation system and a preparation method. The high-solid-phase strong-stability goaf solid waste filling slurry is prepared from the following components: granular coal gangue powder, fine-grain coal gangue powder, a harmful substance curing agent, a dispersing agent, a stabilizing agent and water. The solid waste filling slurry is prepared from the following components in parts by weight: 200 to 500 parts of coal gangue powder, 300 to 600 parts of fine coal gangue powder, 5 to 30 parts of harmful substance curing agent, 3 to 15 parts of dispersing agent, 0.75 to 20 parts of stabilizer and 600 to 800 parts of water. The high-solid-phase strong-stability solid waste slurry does not need to be added with cement type cementing materials, has the advantages of being good in stability, low in bleeding rate, long in diffusion distance and the like, and can effectively fill residual cracks and holes in a goaf. The provided high-solid-phase strong-stability solid waste slurry and the preparation process method thereof are suitable for goaf filling and coal gangue solid waste treatment of western coal mines in China, and green mining of coal mines is achieved.
本发明公开一种高固相强稳定采空区固废充填浆液、制备系统及制备方法，由如下组分组成：粉粒煤矸石粉、细粒煤矸石粉、有害物质固化剂、分散剂、稳定剂和水；固废充填浆液中各组分的重量份为：粉粒煤矸石粉为200～500重量份，细粒煤矸石粉为300～600重量份，有害物质固化剂5～30重量份，分散剂3～15重量份，稳定剂0.75～20重量份，水600～800重量份。该高固相强稳定固废浆液无需添加水泥类胶凝材料，具有稳定性好、析水率低和扩散距离远等优点，能有效充填采空区残余裂隙和孔洞。所提供的高固相强稳定固废浆液其制备工艺方法适用于我国西部煤矿采空区充填和煤矸石固废处置，实现煤矿绿色开采。
