Embodiment Construction

[0031] Below, combined with figure 1 , 2 As well as specific implementation methods, the present invention is further described: a mining platform 210 and a navigation device 220 free near the mining platform 210 are set on the sea level 100, and the mining platform 210 is provided with a mining shaft 211 below the sea level 100 to reach the seabed mining point. With the mining point as the center, three concentric circles are set on the seabed from inside to outside: the first monitoring circle 101 , the second monitoring circle 102 and the third monitoring circle 103 . The in-situ monitoring instrument 304 is set at the bottom of the production shaft 211 for collecting in-situ data; a plurality of seabed submarine mark monitoring instruments 305 are set on the first monitoring circle 101 and the second monitoring circle 102; A plurality of mooring submarine mark monitors 303, the top of the mooring system submarine mark monitors 303 reaches the sea level 100, and the bottom...

Abstract

The invention discloses a marine natural gas hydrate development environment monitoring system and method. On a seabed, with a development point as the center of a circle, three concentric circles which are a first monitoring circle, a second monitoring circle and a third monitoring circle are arranged from the inside to the outside, and an in-site monitor, a seabed submerged buoy monitor and a mooring buoy monitor are arranged. In a development environment, four dimensions of data of an atmosphere, a seabed, seawater and an underground are monitored at the same time, and underground sedimenttemperature pressure / soil mechanics monitoring, seabed deformation monitoring of a mining area, the monitoring of seabed submerged buoy / mooring buoy, ROV-based real-time observation and monitoring, mining products and environmental impact monitoring are related. Monitoring ways cover many subjects of marine geology, engineering geology, physical oceanography, marine chemistry, marine biology and the like. A comprehensive environmental impact assessment technical scheme with the integration of 'seabed sediment, submarine sedimentation, multiple parameters of a submarine boundary layer, longitudinal profile characteristics of seawater, surface seawater and atmosphere, and the production of gas, water and sand' in one body is formed.

Description

technical field [0001] The invention relates to a marine environment monitoring system, in particular to a system for monitoring the marine natural gas hydrate development environment. [0002] At the same time, the invention also relates to a marine environment monitoring method, in particular to a marine natural gas hydrate development environmental monitoring method. Background technique [0003] Gas hydrate is a solid substance formed by combining gases such as methane, ethane, and carbon dioxide with water molecules under high-pressure and low-temperature environments. It mainly exists in land permafrost and marine sediments with a water depth of more than 300m. The total amount of carbon contained in the global natural gas hydrate is equivalent to twice that of the known carbon reserves of coal, oil and natural gas, and when completely burned, only almost pollution-free carbon dioxide and water are produced. It is one of the most promising new green energy sources in t...
