Ore deposit and subterranean heat collaborative exploitation and adjacent stope collaborative cooling method and system

Abstract

The invention discloses an ore deposit and subterranean heat collaborative exploitation and adjacent stope collaborative cooling method and system. The method comprises the first step of conducting mining preparation and cutting on ore blocks according to a mining with filling technology; the second step of conducting construction on an ore deposit subterranean heat exploitation ground system on the ground; the third step of conducting first-layer backstoping, and conducting construction on an ore deposit subterranean heat exploitation underground system underground; the fourth step of conducting first-layer filling to form heat exploitation filling bodies; the fifth step of upwards conducting exploitation, backstoping and filling on all layers from bottom to top in sequence from the upper part of the first layer to a stage haulage roadway. The system comprises the ore deposit subterranean heat exploitation ground system and the ore deposit subterranean heat exploitation underground system, wherein the ore deposit subterranean heat exploitation underground system comprises vertical shaft stand pipes, roadway horizontal tubes and raise stand pipes which are laid when backstoping is conducted in all layers, and the heat exploitation filling bodies which are formed when filling at all layers is conducted. According to the ore deposit and subterranean heat collaborative exploitation and adjacent stope collaborative cooling method and system, the design is novel and reasonable, and the resource recovery and subterranean heat exploitation are achieved; meanwhile, consideration is given to cooling of a high-temperature stope, and the practicability 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 collaborative mining of ore deposits and geothermal energy and collaborative cooling of adjacent stopes. 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 ear...
