Barite 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 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.

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.

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.

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.

The mining methods proposed by Wang Qimin mainly included three types: construction technology, elimination of mining pollution, and deep mining. Among them, construction technology was the key to improving mining efficiency and safety. He suggested establishing a special research institute to study new methods related to construction technology. In addition, he also recommended some management techniques related to mining methods, such as the establishment of a specialized mining organization to coordinate mining activities, the development of unified mining rules to reduce possible conflicts and disputes in mining activities, and the establishment of a mining training system to improve the skills of miners.

There were many options for mining, including exploit, mine, extract, and so on.

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.

The mining methods included underground mining and open-pit mining. Underground mining was the process of extracting ore from the ore blocks in the underground deposit. It was achieved through the mining, cutting, and extraction of the ore blocks. Underground mining methods included natural support mining method, artificial support mining method, and collapse mining method. Open pit mining was a mining method that gradually stripped the rocks and extracted useful minerals from the hillside or depression under open conditions. Compared to underground mining, open-pit mining had the advantages of faster construction speed, higher labor productivity, lower cost, better working conditions, safety, and higher ore recovery rate.

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.
