Answer: The vertical mining and stripping method of open pit mine means that the stripping work line is arranged along the direction of the ore body, and the vertical ore body moves toward the direction. Advantages: 1. During longitudinal mining, the working line is propelled in parallel, and the width of the mining belt along the working line is basically unchanged, which is beneficial to the efficiency of the equipment, and the number of working steps can be reduced; 2. The open trench can be arranged in the ore body The upper plate and the vertical ore body move forward, which is conducive to reducing the loss of ore, depletion and elimination of the stone. Disadvantages: 1. Under certain mining technical conditions, the internal transport distance of the rock is relatively large; 2. When the open trench is arranged in the lower part of the ore body and the working line is pushed from the lower plate to the upper plate, the classification of the ore is more difficult, and the ore is lost. And the depletion is large, and the amount of infrastructure demolition is also large. The lateral mining and stripping method of open pit mine refers to the vertical ore body orientation of the stripping working line and moves along the ore body. Advantages: Under certain mining technical conditions, the amount of infrastructure construction of open pit mines can be reduced, and the internal transport distance of trenches and the amount of trenching works can be reduced. Disadvantages: There are many steps in mining operations, mining equipment is frequently moved up and down, affecting its production capacity, controlling ore loss, depletion is difficult, production organization and management are more complicated, and it is easy to cause mining and stripping due to poor planning.
Release agent is a functional substance between mold and finished product. Release agent has chemical resistance, in contact with the chemical composition of different resins will not be dissolved. Due to the rapid development of injection molding, extrusion, calendering, molding, laminating and other processes, the dosage of release agent is also greatly increased. Our release agent variety, complete specifications, quality assurance!
Release agent is widely used in metal die casting, polyurethane foam and elastomer, glass fiber reinforced plastics, injection thermoplastics, vacuum foam sheet and extruded profiles and other die pressing operations. Sometimes other plastic fillers such as plasticizers leak into the interface during molding, and a surface remover is needed to remove it.
