本发明提供一种可脱离式深海采矿避险系统以及避险方法,包括采矿船、输送管以及采矿车,采矿车通过输送管与采矿船连接,输送管包括:第一提升立管,第一提升立管与采矿车连接;第二提升立管,第二提升立管设于第一提升立管的顶部并与第一提升立管可拆卸连接,当预报有恶劣海况发生需要撤离时,可将第二提升立管可回收至采矿船;可脱离式深海采矿避险系统还包括:重力锚,用于当预报有恶劣海况发生需要撤离时,将重力锚布放于海底,并将重力锚与第一提升立管的底部连接;浮力装置,用于当预报有恶劣海况发生需要撤离时,将所述浮力装置与所述第一提升立管的顶部连接,并将所述浮力装置布放于海面以下至预设深度,缩短为准备规避恶劣海况所需时间。

    The invention provides a separable deep-sea mining risk avoiding system and a risk avoiding method. The separable deep-sea mining risk avoiding system comprises a mining ship, a conveying pipe and a mining vehicle, wherein the mining vehicle is connected with the mining ship through the conveying pipe; the conveying pipe comprises a first lifting vertical pipe and a second lifting vertical pipe; the first lifting vertical pipe is connected with the mining vehicle; the second lifting vertical pipe is arranged at the top of the first lifting vertical pipe and is detachably connected with the first lifting vertical pipe; when a severe sea condition is forecasted to occur and the evacuation is needed, the second lifting vertical pipe can be recovered to the mining ship; the separable deep-seamining risk avoiding system also comprises a gravity anchor and a buoyancy device; the gravity anchor is used for putting the gravity anchor onto the sea bottom when the severe sea condition is forecasted to occur and the evacuation is needed; the gravity anchor is connected with the bottom of the first lifting vertical pipe; the buoyancy device is used for connecting the buoyancy device with thetop of the first lifting vertical pipe when the severe sea condition is forecasted to occur and the evacuation is needed; the buoyancy device is put under the sea surface to the preset depth; and thetime required for preparing the severe sea condition avoidance is shortened.
