The advantages and disadvantages of the VCR method are as follows:
Advantages: working in the mining lane, working condition number, high degree of safety; applying spherical blasting blasting, making full use of explosive energy, uniform breaking degree, good blasting effect; simple structure of the nugget, no need to dig the cutting patio and cutting groove, The amount of cutting engineering is small; if high-efficiency rock drilling and mining equipment is used, the uniformity of blasting ore can greatly improve the shipping efficiency, and the cost of rock drilling and shipping is greatly reduced.
Disadvantages: The process of charging blasting is complicated, it is difficult to realize the charging of mechanical equipment, the labor intensity of workers is high; the cost of using explosives is high; the blasting process is easy to block holes and difficult to handle.
