ZMV soft blasting charges are designed for separating and fragmenting natural rock stone blocks using blasthole and borehole charges, as well as tunnel driving with trim blasting at the ambient temperature of -50°C to +60°C.

Application of ZMV provides for:

·      preventing destruction of stones in the proximity (increasing the output of standard blocks);

·      reducing drilling costs.

ZMV are convenient in use thanks to special centralizers and charging device.
