Problems solved by technology

Even if the overall recovery rate of coal resources in developed countries is about twice that of our country, it cannot maximize the exploitation and utilization of underground mineral resources, and there are also potential safety hazards, which will also cause geological disasters

Embodiment Construction

[0023] Embodiment 1 of the present invention. A safe and green mining method for mining while reinforcing mineral resources, including the following steps:

[0024] a. Blend the fly ash into slurry, and then sieve the slurry with a particle size of 24-300 mesh, then magnetically separate the slurry to select the iron ore in the fly ash, and the fly ash after magnetic separation The slurry is flotation to select bauxite, zinc ore, copper ore, molybdenum ore, tin ore and other valuable mineral resources in the fly ash, and obtain fly ash tailings mainly composed of silicon and calcium; The main components of fly ash are oxides of silicon, aluminum, iron and a small amount of other metals. According to the different geological conditions of each producing area, the minerals contained in fly ash are also different. Through the existing flotation process, the fly ash can be Extract valuable minerals from coal ash, including but not limited to zinc ore, copper ore, molybdenum ore, ...

Abstract

The invention discloses a safe and green mining method for simultaneously reinforcing and mining a mineral resource. The method comprises the following steps of respectively grinding and proportioning coal ash, steel slag and coal gangue into pulp, sieving after proportioning into the pulp, and magnetically separating the pulp to select iron mine; floating the pulp after magnetic separation to select valuable minerals to obtain tailings, and preparing the tailings to obtain the pulp; and pouring the pulp into a mining mine through a pipeline and a hole, and solidifying the pulp to obtain a pouring stone support body to support the geology of the mining area. The mine is supported during mining, and the remaining ore around the mining area is mined. According to the novel safe and green mining technology, the green development and utilization of the resource is perfectly combined with the ecological rehabilitation; and the whole mineral resource is fully developed and utilized in a safe environment, and meanwhile, the green development, the cycle development and the low carbon development are advanced. Moreover, the whole tamping process is cheep in economy and reliable in technology and has a good environment-friendly performance.

Description

technical field [0001] The invention relates to a safe and green mining method for mining mineral resources while strengthening, and belongs to the technical field of mineral mining. Background technique [0002] Due to the continuous development of the economy, the demand for mineral resources continues to increase, especially the demand for coal and metal mineral resources. The pressure of economic development often leads to the situation of predatory and disorderly mining of mineral resources, which further deteriorates The environment of the mining area has led to a serious waste of mineral resources and frequent occurrence of geological disasters. Although my country has promulgated many relevant laws and regulations in recent years, and the mineral recovery rate is gradually increasing, there is still a big gap compared with developed countries. Taking coal as an example, the overall recovery rate of coal resources in developed countries reaches 60% to 70%, while the ...
