The blasting hole of the heading face is divided into a grooving hole, an auxiliary hole and a peripheral hole (shown in Fig. 1).

The function of the slotted hole is to first blast and throw part of the rock on the heading face to form a slotted cavity, forming a second free surface for the auxiliary hole to improve the blasting effect. The gutter hole plays a decisive role in the excavation work. The auxiliary hole is located at the periphery of the groove, and its function is to collapse the large section of the surrounding rock brush. The function of the peripheral hole controls the shape of the roadway section.
