Marine gas hydrate is a new energy in the 21st century with the huge amount of resources and cleaning. But its decomposition and the release can lead to decrease the stability of seabed, causing submarine landslide. And its overflowed can intensify the greenhouse effect, interaction between which can lead to more serious ecological and environmental disasters. All of the exploitation technologies, such as depressurization, thermal methods, chemical injection method, CO2 replacement method, and fluorine gas+microwave method, are limitations in controlling of the decomposed rates and decomposed range. The research based on the marine gas hydrate decomposition caused by vibration, by adjusting the excitation intensity, frequency, and amplitude. Different local oscillator strength applied on the occurrence of gas hydrate layer. Gas hydrate stable state changed in mining region, prompting the gas hydrate conversing from the sediments. Model of the experiment is made for simulations on the decomposition of gas hydrate. This method has a good controllability for the region and the process of mining, avoiding geological disasters and environmental issues in the seabed caused by the mining process.
