An environment-friendly mining method for preventing landslides

Abstract

The invention provides an environment-friendly anti-landslide mining method. The method comprises the following steps: arranging a first layer of top beams on the upper part of a mineral layer, pilingon the lower parts of the first layer of top beams and preparing a first layer of stand columns which upward reach the first layer of top beams; mining the minerals on the lower parts of the first layer of top beams; downward piling on the bottoms of a first layer of mining holes close to the bottoms of the first layer of stand columns, thereby acquiring a second layer of stand columns; preparinga second layer of top beams and pouring the bottoms of the first layer of stand columns and the tops of the second layer of top beams; mining a second layer of minerals on the lower parts of the second layer of top beams; downward pilling on the bottoms of a second layer of mining holes close to the bottoms of the second layer of stand columns, thereby acquiring a third layer of stand columns; preparing a third layer of top beams and pouring the bottoms of the second layer of stand columns and the tops of the third layer of stand columns; mining a third layer of minerals on the lower parts ofthe third layer of top beams; preparing the corresponding layers of stand columns and top beams in turn till mining the bottom layer of minerals. According to the method provided by the invention, the mining rate of minerals is increased, the mining safety is guaranteed and the happening of geological disasters can be prevented.

Description

technical field [0001] The invention belongs to the technical field of mining, in particular to an environment-friendly mining method for preventing landslides. Background technique [0002] The progress of human society is inseparable from minerals, and expanding the development and utilization of mineral resources has played an irreplaceable role in the development and progress of human social civilization. However, a series of serious environmental problems such as landslides, vegetation destruction, and soil erosion caused by mine development have become important factors restricting mine development. [0003] Due to the limitation of the mining depth of the mining equipment, after the upper layer of minerals is mined, the lower layer of minerals needs to be mined, and the minerals in the mine are mined layer by layer; in the existing mining process, after the upper layer of minerals is mined, a layer needs to be left in the middle Minerals are not mined as interlayers,...

AI Technical Summary

Problems solved by technology

[0003] Due to the limitation of the mining depth of the mining equipment, after the upper layer of minerals is mined, the lower layer of minerals needs to be mined, and the minerals in the mine are mined layer by layer; in the existing mining process, after the upper layer of minerals is mined, a layer needs to be left in the middle Minerals are not mined as interlayers, and minerals between the underlying minerals; for example, minerals with a thickness of 30-50 meters are reserved between layers as interlayers, such as figure 1 , figure 2 As shown, the mines that have been mined will collapse after a period of time because the interior is hollowed out, resulting in the destruction of mountain vegetation and the occurrence of geological disasters

And this utilization of minerals as an interlayer leads to a great reduction in the mining rate of minerals, the maximum mining rate is no more than 75%, and there is a great waste of precious minerals

At the same time, for some minerals with soft texture, using minerals as interlayers will also cause potential safety hazards of landslides, resulting in serious dangers in mining operations; for minerals with soft textures, explosives cannot be used for mining, and the use of explosives itself is also safe. risk, but also the risk of landslides
