Title:
FLUIDIZED MINING METHOD OF COMBUSTIBLE ICE THROUGH ROTARY SPRAYING AND PRESSURE RELIEF
Document Type and Number:
WIPO Patent Application WO/2019/010908
Kind Code:
A1
Abstract:
Disclosed is a fluidized mining method of combustible ice through rotary spraying and pressure relief. Situations, such as pressure changes, in a reservoir stratum can be grasped in a timely manner while pressure-relief mining is conducted on combustible ice resources, a corresponding improved treatment is provided, the mining speed can be effectively controlled, and at the same time, information related to the reservoir stratum can be collected, fed back and processed in a timely manner. Meanwhile, the mining method is low in mining cost, easy to implement, high in economic efficiency, simple in mining technology and mature in related application equipment technology, and can also rapidly achieve application in industrial mining.
