Anti-seepage concrete progressive structure for underground goaf and construction method thereof
The invention discloses an anti-seepage concrete progressive structure for an underground goaf and a construction method thereof, belongs to the field of mining, and solves the problem that agents andharmful chemical components in tailings pollute underground water. An anti-seepage concrete bottom layer is laid at the bottom of the goaf, a plurality of layers of anti-seepage bodies are arranged on the inner side wall of the goaf from bottom to top, and an anti-seepage concrete wall is arranged at an entrance and an exit of the goaf. The construction method comprises the following steps: pumping anti-seepage concrete to the bottom of the goaf to form the anti-seepage concrete bottom layer; pumping quick-setting anti-seepage concrete along the lower end of the inner side wall of the goaf toform a first layer of anti-seepage body, and then filling the first layer of tailings; pumping a second layer of quick-setting anti-seepage concrete along the inner side wall of the goaf, and fillingthe second layer of tailings; and repeating the operation; and pouring an anti-seepage concrete wall at the entrance and the exit of the goaf. According to the invention, agents and harmful chemicalcomponents in tailings can be effectively prevented from seeping out along rock cracks and polluting underground water. The construction method is easy.
本发明公开了一种用于地下采空区的防渗混凝土渐进结构及其施工方法，属于采矿领域，解决尾砂中的药剂和有害化学成分污染地下水的问题。本发明在采空区的底部铺设有防渗混凝土底层，在采空区的内侧壁由下至上设有多层防渗体，在采空区的出入口处设有防渗混凝土墙。施工方法：向采空区底部泵送防渗混凝土，形成防渗混凝土底层；沿采空区内侧壁下端泵送快凝防渗混凝土，形成第一层防渗体，然后进行第一层尾砂的填充；沿采空区内侧壁泵送第二层快凝防渗混凝土，填充第二层尾砂；如此重复操作；在采空区的出入口处浇筑防渗混凝土墙。本发明可有效防止尾砂中的药剂和有害化学成分沿岩体裂隙渗出，防止其污染地下水。本发明施工方法容易。
