Barite mining method
Barite mining methods included open pit mining and underground mining. Opencast mining was to excavate ore from the surface of the ground through blasting and excavation machinery. Underground mining was done by digging tunnels into the deposit. The specific mining process included ore exploration, ore mining, ore crushing and grinding, mineral processing and filling. The mining equipment commonly used in underground mining included hand-pushed rubber-tyred vehicles, winches, and local fans. The open-pit mining mainly used equipment such as loaders and dump trucks.
coal mining method
There were many ways to mine coal. The following conclusions were made: The methods of coal mining could be divided into underground mining and open-pit mining. Underground mining was divided into two categories: wall mining and pillar mining. The wall mining method was featured by a long coal wall, and the roadways at both ends of the working face were used for air intake, air return, coal transportation, and material transportation. The pillar mining method was featured by a short coal wall in the shape of a square pillar, and a large number of working faces were mined at the same time. The specific coal mining methods included strike longwall mining method, inclined longwall mining method, inclined slicing mining method, and longwall top coal mining method. The strike longwall mining method was a mining method that advanced along the strike, the inclined longwall mining method was a mining method that advanced along the inclined, the inclined slicing mining method was a mining method that divided the thick coal seam into slices along the inclined plane, and the longwall top coal mining method was a mining method that first mined the coal at the bottom of the longwall working face of the gently inclined thick coal seam, and then used the top coal mining method. In addition, open-pit coal mining was also a common method of coal mining. The open-pit coal mining has the characteristics of large mining capacity, fast construction speed, high labor efficiency, low production cost, excellent labor environment, guaranteed safety, and high resource recovery rate. Open pit mining had become the main method of coal mining in the world's major coal mining countries. In summary, coal mining methods included underground mining and open pit mining. Underground mining was divided into two categories: wall mining and pillar mining. The specific methods included strike longwall mining, inclined longwall mining, inclined slicing mining, and longwall top coal mining. Opencast coal mining was also a common method.
diamond mining method
Diamond mining methods mainly included alluvial mining, pipeline mining, and ocean mining. Alluvial mining was the oldest method of collecting diamonds by sorting the deposits on riverbeds or beaches. Pipelined mining was divided into two forms: open mining and underground mining. Open mining was closer to the surface, while underground mining required a tunnel to enter the ground to extract diamonds. Ocean mining was a relatively new method. It used ships to extract sand from the bottom of the sea and then look for diamonds in the rocks. These mining methods were used in diamond deposits all over the world.
Crosscut mining method
The mining method was to divide the mine into horizontal layers according to a certain height. Starting from the highest point of the mountain, the mining method was to mine layer by layer from top to bottom. This kind of mining method could form a wide platform, leaving no side slope or leaving a gentle side slope, thereby reducing the cost of ecological restoration, reducing the hidden dangers of mine safety, improving the level of resource utilization, and improving the comprehensive social benefits. The cross-cutting mining method promoted by the Natural Resources Department of Hebei Province was in a leading position nationwide.
Open pit mining method
The open-pit mining method mainly included the technological processes of drilling, blasting, mining, transportation, and rock discharge. Piercing work was the primary process of open-pit mining. It was done by a down-the-hole drill or a roller drill to control the ore grade and improve the blasting quality. Explosions were used to blast rocks or rock formations to facilitate subsequent mining operations. Mining and transportation was the transportation of ore from the open space to a designated location. It was usually operated by excavators, cars, electric vehicles, and other equipment. Rock removal was to remove the rocks or rock layers produced during the mining process to maintain the unobstructed flow of the mining area. The open-pit mining method has the characteristics of large mining space, excellent working conditions, high labor productivity, and low mining costs.
Xinghe County Mo Ore Mining Method
The mining method of Xinghe County's Mo ore was mainly open-pit mining. In document 1 and document 2, it was mentioned that the Xinghe County Mo Mine mainly used open-pit mining. In addition, document 5 also mentioned that the mining method of Xinghe County's Mo deposit had changed from underground mining to open-pit mining. Therefore, it could be confirmed that the mining method of Xinghe County's Mo mine was open-pit mining.
Mining
Mining referred to the act of digging or taking action, especially the digging of minerals or the extraction of underground resources. For example, oil mining, coal mining, and so on. The mining process involved digging ditches and culverts. Green mining was a theoretical basis. It focused on the rules of joints, fissures, and separation formed by the movement of key layers in the rock formation after mining, as well as the laws of gas and underground water infiltration in the broken rock formation. The main contents of the green mining technology included water-preserving mining, mining under buildings and layer separation by injection to reduce settlement, strip and filling mining, coal and gas co-mining, coal tunnel support and underground disposal of some waste rock, underground coal vaporizing, etc. In short, mining referred to the process of digging or taking action to obtain minerals or underground resources.
ore mining
The methods of mining included blasting and excavation. The mining process required the use of drilling machines, blasting equipment, mining loaders, mining cars and other mining equipment, as well as open-air mineral processing machines, mineral processing flotators, magnetic separation machines and other mineral processing equipment. In addition, transportation equipment such as trucks, trains, and conveyor belts were also needed, as well as auxiliary equipment such as water treatment equipment, air treatment equipment, and power equipment. Ore mining needed to pay attention to environmental protection, production safety, and social responsibility. The specific mining process and equipment selection needed to be determined according to the characteristics and requirements of the deposit.
mining of ore
The specific process of mining ore included exploration, mining, and protecting the integrity and quality of the jade. In the exploration phase, geological exploration was needed to find places that might be rich in jade ore. In the mining stage, the jade ore could be extracted from the ore body by means of blasting, excavation, and ore sorting. During the entire mining process, environmental protection, production safety, and social responsibility needed to be paid attention to. The environmental protection included the rational planning of Kuangqu, the treatment and recycling of waste water and waste residue, and the reduction of damage to the ecological environment. In terms of safety production, they needed to strictly follow the safety production regulations and adopt the necessary safety facilities and measures to ensure the personal safety of workers. In terms of social responsibility, it was necessary to actively communicate and cooperate with the local government and residents, abide by local laws and regulations, respect local culture and customs, and fully consider the interests of local residents to ensure that mining had a positive contribution to local social and economic development. The specific mining process also included ore testing, ore analysis, handling certificates, determining the mineral processing method, checking the site situation, providing the mineral processing process flow chart, allocating mineral processing equipment, site foundation treatment, equipment installation and adjustment, normal production after trial operation, and finished product sales.
