在水体下采矿需要注意这样两个问题: 保持水体的天然状态;防止采矿巷道突然涌水(事故性涌水)——这种涌水可能导致矿山局部或全部被淹。采矿作业会引起水体水文地质动态的变化,这是因为采矿巷道的渗透系数增大以及水体的自然条件受到破坏(改变了水流坡度或水体边界等等)。在水体下进行采矿,必须考虑到采矿巷
Mining under water requires attention to two issues: maintaining the natural state of the water; preventing sudden gushing (accidental gushing) of the mining roadway - which can result in partial or total flooding of the mine. Mining operations can cause changes in the hydrogeological dynamics of the water body due to the increased permeability coefficient of the mining roadway and the destruction of the natural conditions of the water body (changes in water flow slope or water body boundaries, etc.). Mining under water must take into account the mining lane
