What is the explosive force, what is its application condition?

Explosive force transfer is applied to the open field method. Therefore, its application conditions are:
1. The inclination of the ore body is 30°~50° . Because the ore body inclination angle is in this range, it is difficult to use electric raft transportation and gravity self-slip blasting;
2. The ore and surrounding rock are stable. When using the wrong bar top and left reinforcing layer protective roof ore (ore were available low value), roof slate stone is not strong enough to be employed explosion force;
3. The thickness of the ore body is about 2~10m , the thickness of the ore body is small, the clamping property is large, and the distance from the explosive force to throw the ore is small. The thickness of the ore body is very large, and only part of the ore (close to the bottom plate) should be transported by explosive force.
