| Abstract: | The mechanism of cracking by pre splitting blasting with water in hole by means of experimental and analytic method is studied.It establishes the reference of beginning, widening and ceasing of crack caused by pre splitting blasting with water. Via lab experiment and theoritic analysis the advantage of the method has been proved. |
