The Coal-weakening Technique of Hydraulic Coal Mining Loose Blasting
The work efficiency is usually very low in hydraulic coal mining because of the hard medium. Its a simple and efficient method of improving the work efficiency to use the technique of loose blasting to weaking coal and mining coal by water power. Hasting are designed in this essay according to the existential condition, physical mechanical property and controlled blasting principles of the coal. The rationality of the parameters designed has been proved by finite element numerical simulation. Good results have been achieved in field engineering practice and it is worth generalization and application.
