Mining Ecological Safety Problems Mineral resources are the important material base of human society development.
The rapid development and utilization of mineral resources has provided the important material guarantee for social economy fast and steady development.
In addition, the reputation of "the home of non-ferrous metals" also only means the supply of raw materials, and don’t combined non-ferrous metal advantages with metallurgy, materials of industry development.

Orthogonal experiment of slit-charge structural parameters The slit-charge structural factors are slotted pipe materials, slotted pipe wall thickness, cutting seam width, cutting seam length and decoupling ratio.
The most important influencing factor of the slit-charge’s blasting effect is tube material.
In the four contrasting materials iron pipe’s blasting effect is the best, paper tube is the worst, PP and PVC materials are probably similar and in the middle of all.
Comprehensive consideration of various factors, such as to meet the engineering requirements, a wide sources of the selected material, reasonable price, the site easy to operate, the PP material is chose.
