Preparation method of coal gangue-based fine particle filling material
The invention relates to a preparation method of a coal gangue-based fine particle filling material, which comprises the following steps of by taking coal gangue and fly ash as raw materials, pressurizing and foaming through a foaming agent, and stirring with water to form the coal gangue-based fine particle filling material. In positions such as an abutment back backfilling area, a roadbed filling area, a goaf and the like, the prepared coal gangue-based fine particle filling material has self-compaction performance and good fluidity, does not need to be vibrated and compacted, further has the characteristics of light weight and high strength, and reduces excessive stacking load. According to the method, industrial solid waste can be fully utilized to prepare the light high-strength flow-state filling material, accumulation and spontaneous combustion of the coal gangue are reduced, carbon emission is reduced, and environmental protection and reduction of mining of soil resources are facilitated.
本发明专利涉及一种煤矸石基微细颗粒填充材料制备方法，利用煤矸石、粉煤灰作为原材料，通过发泡剂加压发泡和水搅拌在一起，形成煤矸石基微细颗粒填充材料；在台背回填区域、路基填筑区域、采空区等位置，制备的煤矸石基微细颗粒填充材料具有自密实性，具有很好的流动性，无需振捣及压实，还具有轻质、高强的特点，减少过多的堆积荷载。本发明可以充分利用工业固废来制备轻质高强流态填充材料，减少煤矸石的堆积自燃，降低了碳排放，有利于环境的保护和减少土资源的开采。
