Problems solved by technology

[0003] How to mine these combustible ices has been studied all over the world, but there has been no better method. The main problem is that during the mining process, the gasification of combustible ices leaks into the air, causing the greenhouse effect and causing global warming. The climate is getting warmer, and the mining subsidence of the ore body is very likely to cause safety accidents

Abstract

The invention relates to the technology of natural gas extraction, in particular to a device and method for exploiting seafloor combustible ice. The device comprises a sea surface operation platform and is characterized in that a traction rope is connected to the bottom of the sea surface operation platform, a ceiling curtain is connected to the tail end of the traction rope, and a supporting structure is arranged in the curtain; a bearing column is connected to the supporting structure and vertically arranged on an exploitation operation area, the ceiling curtain covers the upper portion of the exploitation operation area, and the ceiling curtain and the bearing column form a closed space. The device has the advantages that leakage of volatile combustible ice gas is avoided, the possibility of mining area collapse is reduced, and the device is beneficial to guarantee of ecological balance of the earth and life safety of operation personnel.

Description

(1) Technical field [0001] The invention relates to natural gas mining technology, in particular to a device and method for mining seabed combustible ice. (2) Background technology [0002] Combustible ice is natural gas hydrate (Natural Gas Hydrate, referred to as Gas Hydrate) distributed in deep-sea sediments or permafrost on land. It is an ice-like crystalline substance formed by natural gas and water under high-pressure and low-temperature conditions. It is called "combustible ice", "solid gas" or "air ice" because of its ice-like appearance and its ability to burn when exposed to fire. [0003] How to mine these combustible ices has been studied all over the world, but there has been no better method. The main problem is that during the mining process, the gasification of combustible ices leaks into the air, causing the greenhouse effect and causing global warming. Climate warming, and mine goaf subsidence can easily lead to safety accidents. [0004] Therefore, it is...
