The invention discloses a method for treating alkaline solid waste and filling a goaf, which comprises the following steps of: 1, crushing the alkaline solid waste into powder to obtain a reactant A; 2, ventilation air methane discharged by a mine is introduced into water, and a reactant B is obtained; 3, the reactant A and the reactant B are transported to an underground goaf needing to be filled from the ground through pipelines; wherein the reactant A is a solid, and the reactant B is a liquid. According to the method for treating the alkaline solid waste and filling the goaf, solid matter which is harder and small in particle size is generated through the liquid-solid reaction and can make good contact with a goaf top plate, a goaf bottom plate and surrounding rock, and the effects of tight contact, underground reaction, simple operation and high-strength filling are achieved.
本发明公开了一种处理碱性固体废物并以填充采空区的方法，包括以下步骤：步骤1：将碱性固体废物破碎至粉末状，得到反应物A；步骤2：将矿井所排的乏风通入水中，获得反应物B；步骤3：所述反应物A和反应物B均通过管道从地面运输至需填充的井下采空区；其中，所述反应物A为固体，所述反应物B为液体。本发明提供的一种处理碱性固体废物并以填充采空区的方法，通过液固反应生成更为坚硬、粒度小的固体物质，并能够很好的与采空区顶板、采空区底板、围岩接触，达到紧密接触，井下反应，操作简单，高强度充填的效果。
