Static blasting method for rock mass without free boundaries

The invention relates to a static blasting method for a rock mass without free boundaries. The method comprises the following steps that 1) a blasting region and a blasting boundary are determined; 2), holes are formed in the explosion boundary, charge loading holes and compensation holes are formed in the explosion region; and 3) static crushing substances are added into the charge loading holes,and static blasting is carried out. Compared with the prior art, the method has the advantages that an artificial free boundary is constructed in the rock mass without the free boundaries, the compensation holes which are formed in a quincunx shape with the charge loading holes are additionally arranged inside the explosion region, so that the constraint of a to-be-blasted rock mass is reduced, ato-be-blasted region is fully covered by a high-stress region, the purpose of effectively crushing is achieved, the method is suitable for static blasting for the rock mass without free boundaries orwith few free boundaries,
