Abstract

The invention discloses a collaborative mining method and system for ore deposit and terrestrial heat. The collaborative mining method comprises the steps that firstly, ore block accurate mining and cutting are conducted according to the cut and fill mining technology; secondly, construction of a mine terrestrial heat mining ground system is conducted on the ground; thirdly, first-layer back production is conducted, and construction of a mine terrestrial heat mining underground system is conducted below the ground; fourthly, first-layer filling is conducted, and a heat collecting filling body is formed; and fifthly, from the part above the first layer, mining, back production and filling of various layers are sequentially conducted from bottom to top till the operation is conducted upwards to a stage transporting roadway. The collaborative mining system comprises the mine terrestrial heat mining ground system and the mine terrestrial heat mining underground system. The mine terrestrial heat mining underground system comprises a vertical well vertical pipe, a roadway transverse pipe, a top well vertical pipe and the heat collecting filling body, wherein the vertical well vertical pipe, the roadway transverse pipe and the top well vertical pipe are laid during back production of the layers, and the heat collecting filling body is formed during layer filling. Design is novel and reasonable, resource recovery and terrestrial heat development are conducted, meanwhile, high-temperature stope cooling is combined, practicability is high, and the application and popularization value is high.

Description

technical field [0001] The invention belongs to the technical field of mining of deep mineral resources, and in particular relates to a method and system for synergistic mining of ore deposits and geothermal heat. Background technique [0002] With the gradual reduction and depletion of shallow mineral resources, the development of deep mineral resources is a major demand for the country to ensure resource security and expand economic and social development space. At the same time, the development and utilization of deep mineral resources is also in line with the strategic requirements of the four areas of "deep space, deep sea, deep blue and deep ground" proposed in the "National Medium and Long-term Science and Technology Development Plan (2006-2020)". Ultra-large and ultra-deep deposit mining technology is an important field of "deep" exploration, a strategic technological problem that must be solved in the march to the earth's deep mineral resources, and it is also a hig...
