Method for preparing cemented filling material by compositely exciting coal gasification slag based on response surface method
The invention aims to provide a method for preparing a cemented filling material by compositely exciting coal gasification slag based on a response surface method, and belongs to the technical field of mineral engineering. Coal gasification slag superfine powder for preparing the filling material is obtained through ball milling on the basis of sorting the coal gasification slag, removing impurities and airing; the preparation method comprises the following steps: crushing and screening coal gangue by using a crusher to obtain coarse aggregate, medium aggregate and fine aggregate for preparing the filling material, and uniformly mixing cement, coal gasification slag superfine powder, coal gangue aggregate, an exciting agent and water to prepare the cemented filling material. The problem that the volcanic ash activity of the coal gasification slag is low can be solved, the problems of shortage of cemented filling materials and high filling cost in the cemented filling mining process are effectively controlled, sustainable development is guaranteed, the widely-stacked coal gasification slag is effectively utilized, and the coal gasification slag is recycled. The pollution hazard to the surrounding environment and the occupation of large-scale land are reduced.
本发明的目的在于提供一种基于响应面法复合激发煤气化渣制备胶结充填材料的方法，属于矿业工程技术领域，本发明在分拣煤气化渣去除杂质并晾晒的基础上，通过球磨得到了制备充填材料的煤气化渣超细粉体，然后用破碎机对煤矸石进行破碎和筛分，得到了制备充填材料的粗骨料、中骨料和细骨料，最后将水泥、煤气化渣超细粉体、煤矸石骨料、激发剂和水，混合均匀，制备得到胶结充填材料。本发明不仅可以解决煤气化渣火山灰活性较低的问题，并且有效控制了胶结充填开采过程中胶结充填材料短缺，充填成本高的问题，保障可持续发展，并且有效的利用了广泛堆积的煤气化渣，减轻了对周围环境的污染危害和大规模土地的占用。
