Rock burst drilling device based on pressurizer and rock breaking method

The invention relates to drilling engineering technologies, and provides a rock burst drilling device based on a pressurizer. The rock burst drilling device based on the pressurizer comprises a pressurizer shell and an upper joint. The pressurizer shell is provided with a normal pressure pipe and a high pressure pipe. An upper valve plate, a lower valve plate and a driving part are arranged in the pressurizer shell. A first through hole is vertically formed in the upper valve plate, and a second through hole and a third through hole are formed in the lower valve plate. A piston and a piston rod are further arranged inside the pressurizer shell. A first chamber is formed between the piston and the lower valve plate. A second chamber is formed between the piston and the pressurizer shell. A third chamber is formed between the piston rod and the high pressure pipe. A first control valve is arranged inside the high pressure pipe. The third chamber communicates with the outer side of the pressurizer shell through a second control valve. The invention further provides a rock breaking method involving the rock burst drilling device. Water bombs are jet periodically at the position of the high pressure pipe so as to bombard rock, the rock breaking efficiency is improved through a rock burst inducing mode, the purpose of high-speed drilling can be achieved, and the reliability and service life of a drill bit can be guaranteed.
