Description

technical field [0001] The invention belongs to the field of mining and utilization of coal mine resources, and in particular relates to TBM-based coal mine resource flow phase development equipment and a TBM-based coal mine resource flow phase development method. Background technique [0002] With the gradual depletion of coal mine resources in the shallow part of the earth, the development of coal mine resources continues to move toward the deep part of the earth. At present, the mining depth of coal mine resources has reached 1,500 meters. The existing coal mine resources are exploited in the form of solid-phase development, which requires a lot of manpower to mine and transport the mined coal to the surface. The mined coal mines are screened, and the thermal power plants and gasification workshops on the surface are used to generate electricity and produce gas. This development method mainly has the following shortcomings: [0003] (1) Transporting the coal mined underg...

Problems solved by technology

[0003] (1) Transporting the coal mined underground to the ground requires a large amount of ground space for storage, and building facilities such as concentrators, thermal power plants, and gasification workshops on the ground also requires a large amount of space, and thermal power generation will generate A large amount of coal slag, and when the grade of the coal mine is low, a large amount of tailings will be produced in the mineral processing, these coal slag and tailings are usually piled on the ground, waiting to be processed separately, which will also take up a lot of space, all of which will lead to coal mining and Subsequent conversion and utilization require a large amount of land acquisition, which has the problem of high cost; (2) It takes a lot of energy to transport the coal mines mined from the underground to the ground, and, with the different geological conditions on the ground, the mining points of some coal mines The arrangement of mineral processing plants, thermal power plants, gasification workshops, etc. on the ground is relatively scattered, and it usually needs to rely on rails to transfer materials between various processes, which will also lead to excessive energy consumption; (3) ground mineral processing gangue, waste slag, dust, CO 2 There are many exhaust gases, which will aggravate surface pollution; (4) The construction and maintenance of facilities such as ground mineral processing plants, thermal power plants, and ground transportation tracks all require high costs; Intensive, high labor-intensive, coupled with poor underground conditions, frequent safety accidents, high casualty rate; (6) Due to the need for a large number of manpower to mine, and with the increase of mining depth, the underground working environment will become more and more serious. The worse it is, for example, high temperature and other issues, when the mining depth increases to a certain level, the underground environment is no longer suitable for human survival and work. It is estimated that the current limit depth of the solid phase mining method for coal resources cannot exceed 6,000 meters. Realizing the mining and utilization of coal resources with a depth of more than 6,000 meters is an unattainable luxury for human beings

[0004] Based on the above-mentioned technical status, if we can subvert the existing coal mine resource development technology, develop coal mine resource flow phase development equipment and development methods, and realize the mining and utilization of coal mine resources without people going down the well and coal up the well, it will be of great help to solve the existing coal mine mining methods Existing problems such as high energy consumption, high cost, mining personnel safety, environmental pollution, and inability to realize deep mining will all have positive significance
