Filling material containing lepidolite slag as well as preparation method and application thereof
The invention relates to a filling material for lepidolite slag as well as a preparation method and application of the filling material, and belongs to the technical field of the filling of lepidoliteslag. Slurry formed by mixing the prepared filling material with water has the viscosity close to that of water, is easy to pump (the pumping distance can reach 100-500 m), excellent in thixotropy and short in initial setting time (shorter than 60 s), and overcomes the defects of long initial setting time of a product, proneness of the slurry to flowing, and poor accumulation effect in the priorart. According to the filling material prepared by the invention, 100% consolidation is realized, the highest compressive strength can reach 5MPa, and the problems of poor consolidation performance and low compressive strength of the product in the prior art are solved. According to the high-water-content filling material prepared by the method, complex auxiliary treatment such as filling templatesupporting is not needed in a construction process, and a filling process is simple, and the high-water-content filling material is particularly suitable for meeting a rapid filling requirement underemergency conditions in mines.
本发明涉及一种用于锂云母矿渣的充填材料及其制备方法和应用，属于锂云母矿渣的充填技术领域。本发明制备的充填材料，与水混合后形成的浆料，具有接近水的粘度，易于泵送（泵送距离可达100m‑500m）、优异的触变性和快速的初凝时间（小于60s），解决了现有专利技术产品初凝时间长，浆料易流淌，堆积效果差的不足；本发明制备的充填材料，100%固结，抗压强度最高可达到5MPa，解决了现有技术产品固结性能差，抗压强度低的问题。本发明制备的高水充填材料，施工过程中无需充填模板支护等复杂辅助处理，充填工艺简单，尤其适用于矿井中紧急情况下快速充填需求。
