    Abstract:

    According to the test results of expanding pressure of large borehole static cracking，the reaction mechanism of large borehole static cracking agent is analysed. Based on momentum balance principle, a new sealing device was invented and has been successfully applied to analogue cutting engineering practice. The hole-spacing approximate calculation formula is modified with test data of cutting practice. The technology has some reference to cutting engineering practice in conditions of small interval intersection.
