First, the loading operation 1, mining equipment Open pit mining equipment mainly includes: excavators, bucket shovel, hydraulic shovel and tire type front loading machine. 2. Safety requirements for mining operations (1) When two or more excavators work on the same platform, a certain safety distance should be maintained between the excavators. When using automobile transportation, the distance shall not be less than 3 times of the maximum digging radius and shall not be less than 50m; when transported by electric motor vehicle, it shall not be less than the length of two trains. (2) The excavator working at the same time in two adjacent stages must be staggered by a certain distance in the direction of the stage. In the upper stage, the excavator for the auxiliary work of the edge belt must advance the distance of the excavator with the maximum digging radius of 3 times. And must not be less than 50m. (3) Excavator walking should comply with the following regulations: (4) When excavating work, the following regulations shall be strictly observed: (5) When the bulldozer is working, the following rules should be observed: Second, transportation operations In the open-pit mining process, the capital construction investment of mine transportation accounts for about 60% of the total investment in mine infrastructure. The transportation cost and labor volume account for more than half of the total ore cost and total labor, respectively. An important position in mining. 1, transportation mode Open pit and medium-sized metal and non-metallic mineral mode of transport used mainly include the following: Third, mining and transportation The installation and transportation are inseparable, and the two influence each other and restrict each other. 1. Selection of excavators The selection of the single bucket excavator should be determined according to the scale of the mine, the total amount of mining and stripping of the rock, the mining process, the physical and mechanical properties of the rock, and the supply of equipment. 2. Selection of dump trucks 3. Reasonable ratio of mining and transportation equipment At present, the development trend of the loading and transportation process is mainly reflected in the large-scale production and transportation equipment, the integration and continuity of the loading and transportation links, and computer automation. Stainless Steel Cut Wire Shot As Conditioned
Cut Wire Shot is a very important and popular Metal Abrasive.It is often utilized in shot peening processes when ferrous contamination of work piece is forbidden. As the most cost-effective one, the stainlesss steel cut wire shot, also named Stainless Steel Shot, is widely used for shot peening processes on stainless steel or inconel parts. When Blasting stainless work pieces or other metals need to be down as a pristine surface, stainless cut wire may be a very good metal abrasive to take into consideration. Stainless Steel Cut Wire shot as conditioned is usually used for shot peening processes on stainless steel or inconel parts. As for Longlived stainless steel cut wire shot, the minimum diameter could be 0.15mm and maximum diameter is 3mm. If you want, it could be bigger as your demand.
Concerning stainless steel cut wire shot, it has a very bright surface, maintains its shape longer then cast abrasives and it has a dust free surface. Stainless Steel Cut Wire is available as cut or conditioned and with various chemical compositions.The bulk density of stainless steel cut wire shot is very high and must be taken into consideration in relation to its use in equipment. Suitable equipment must be selected to convey stainless steel shot.
Generally, stainless steel cut wire shot could be classfied into two kinds. One is Stainless Steel Cut Wire Shot AS Cut and as conditioned. And then, stainless steel cut wire shot as conditioned could also be divided into three small groups according to their different roundness and they are G1, g2, G3.

A text to understand the mining technology of open pit mines (production and transportation articles)
The loading operation is to use the loading machinery to excavate the ore directly from the underground or the explosion, and load it into the compartment of the transportation machinery or directly to the designated place. It is the central link of the open-pit mining process, and other production processes such as wearing and blasting, transportation, etc. are all for the purpose of loading and unloading.
