Activated gasified slag, preparation method thereof, grouting reinforcement material and application thereof
The invention provides activated gasified slag, a preparation method thereof, a grouting reinforcement material and application of the grouting reinforcement material. The preparation method comprises the steps of drying and screening, mechanical activation, pre-chemical activation and chemical activation, and the mechanical activation comprises the steps of carrying out first ball milling on pretreated gasification slag obtained after drying and screening to obtain primary ball-milled gasification slag, mixing the primary ball-milled gasification slag with a grinding aid, and then carrying out second ball milling to obtain mechanically activated gasification slag; the pre-chemical activation comprises the steps of mixing the mechanically activated gasification slag with the salt-containing wastewater, and then keeping the temperature and standing. By applying the technical scheme provided by the invention, the technical problems of high-valued and large-scale utilization of the gasified slag and softening and disintegration characteristics of soft rock in a coal mine tunnel when meeting water can be fundamentally solved.
本发明提供了一种活化气化渣、其制备方法、注浆加固材料及其应用。该制备方法包括干燥筛分、机械活化、预化学活化以及化学活化，其中机械活化包括对干燥筛分后得到的预处理气化渣进行第一球磨，得到一次球磨气化渣，将该一次球磨气化渣与助磨剂混合后进行第二球磨，得到机械活化气化渣；预化学活化则包括将机械活化气化渣与含盐废水混合后保温静置的步骤。应用本发明的技术方案，可从根本上解决气化渣高值化、规模化利用和煤矿巷道软岩遇水软化崩解特性的技术难题。
