Problems solved by technology

This scheme will produce shear walls and support structures in secondary construction, but these structures cannot function in mining, which is very wasteful

Embodiment 1

[0030] Embodiment 1 of the present invention: a mining method combined with underground warehouse construction, such as Figure 1 ~ Figure 3 As shown, mining is carried out using the open field method or the artificial mixed partition mining method. During the mining process, the design standards for permanent underground buildings are adopted to carry out surrounding rock support and groundwater seepage prevention; Anti-leakage treatment will be carried out in the area, and then functional decoration will be carried out as an underground warehouse.

[0031] Specifically, for difficult-to-mining ore bodies with rich groundwater and unstable ore rocks, the artificial mixed partition wall mining method is used for mining; if the ore and surrounding rock are stable, the open field method is used for mining.

[0032] The described method of mining with artificial mixed partition wall may specifically include:

[0033] S1, according to the shape of the ore body, build a complete m...

experiment example

[0051] Experimental example: A large iron ore deposit in a certain orefield in eastern Hebei belongs to the Anshan-type sedimentary metamorphic rock type, overlying deep and thick Quaternary water-bearing strata, thick weathered rock layers, huge ore bodies, and low grade. One of the mines is designed to produce 20 million tons of iron ore mine. The unfavorable condition for mining is that there are villages and roads on the surface. The water system network of the Luan River on the surface is fully developed, the depth of underground water is shallow, and there are various channels between the Quaternary water and bedrock and ore body water. The ore body and surrounding rock are destroyed by multiple faults and broken zones, which belong to moderately stable ore body and rock mass. The favorable conditions are: 20 kilometers away from the entrance of the expressway in the north, 15 kilometers away from the high-speed railway station, and 85 kilometers away from the port in t...

Abstract

The invention discloses a mining method combined with contruction of an underground warehouse, which adopts an open-stope method or an artificial mixing partition-wall mining method to perform the mining; and after the mining is ended, the leak-proof treatment is performed for a gob, and then the gob is functionally decorated to serve as the underground warehouse. According to the mining method ofthe invention, the advanced treatment is performed in the aspect of supporting and water and leak resistance in the early stage, the safety and high efficiency of the mining activity can be ensured.Meanwhile, compared with the pure underground grain storage house, since the expense for exploiting the underground passage and digging chambers at the preliminary stage is not needed, the construction expense of the underground warehouse relative to the income can be neglected; and meanwhile, the safety and environmental protection requirement is easy to meet, and the maintenance expense is relatively low. The invention also discloses a ventilation cooling system of a goaf warehouse. The high-efficiency ventilation and cooling can be performed for the goaf warehouse storing the grains.

Description

technical field [0001] The invention relates to a mining method combined with underground warehouse construction and a ventilation and cooling system, belonging to the technical field of underground ore body mining. Background technique [0002] There is a kind of underground ore body, which has to face the following problems during mining: abundant groundwater, weak ore or surrounding rock, and important facilities on the surface, etc., but at the same time has the following advantages: close to the city, convenient transportation, and a port. In the past, when mining was purely for the purpose, the water blocking and supporting funds invested in solving groundwater leakage and weak surrounding rocks seemed too huge, which often made mining economically unreasonable. At the same time, at the end of mining, a large sum of money is needed to deal with the goaf, otherwise there will be man-made geological disasters such as subsidence. [0003] my country is a country with a l...
