Embodiment Construction

[0053] Such as figure 1 Shown, ore deposit of the present invention and geothermal collaborative mining method comprise the following steps:

[0054] Step 1. According to the filling and mining process, mining and cutting of ore blocks are carried out to form a patio 1, a connecting roadway 2, a stage transportation roadway 3, a shaft 4 and a mining space;

[0055] Step 2: Carry out the construction of the ground system for mine geothermal mining on the ground. The specific construction process is: a collector device 10 for storing cold heat exchange fluid and a heat storage fluid device 11 for storing hot heat exchange fluid are installed on the ground, And the cold heat exchanger 15 that is used to supply heat for the residential / office area 16 is set at the residence / office area 16; The heat exchange fluid delivery pipe 19 is connected to the ground fluid delivery pipe 12 at the fluid outlet of the fluid collector 10, connected to the fluid power pump 13 on the ground flui...

Abstract

The invention discloses a method and system for synergistic mining of ore deposits and geothermal energy. The method includes steps: 1. Mining and cutting of ore blocks according to the filling mining process; 2. Construction of the mine geothermal mining ground system on the ground; 3. Carry out the first layered mining, and carry out the construction of the mine geothermal mining underground system underground; 4. Carry out the first layered filling to form a heat mining filling body; Layered mining, mining and filling, up to the stage transportation roadway; its system includes the mine geothermal mining ground system and the mine geothermal mining underground system, the mine geothermal mining underground system includes the vertical shaft riser and roadway laid during the layered mining Horizontal pipes and riser pipes, as well as heat recovery filling bodies formed when filling in various layers. The invention is novel and reasonable in design, takes into account the cooling of high-temperature stope at the same time of resource recovery and geothermal development, has strong practicability, and has high popularization and application value.

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...
