6 FAQs about [Gypsum mine energy storage]

Can gypsum mines be used for crude oil storage?

If the construction of crude oil storage based on the underground space of gypsum mines is feasible, it will represent a new way in which anhydrite goaves can be utilized while, at the same time, enriching crude oil storage methods, saving capital related to building storage facilities, and improving China’s energy storage capacity.

Does gypsum mining use a rock infiltration loading device?

In order to realize the comprehensive utilization of the underground space formed by gypsum mining, with the core goal of building an oil storage depot in the gypsum mine goaf, the designed rock infiltration loading device was used to prepare gypsum rock samples immersed in oil for 0, 15, and 30 days for rock mechanics experiments.

How gypsum is mined?

The mining of gypsum mines is mostly carried out using the open field method, so a large number of goaves are inevitably formed after mining is completed. With the gradual increase in the exposed area and the influence of surrounding loads, accidents such as pillar deformation and roof collapse are prone to occur in the goaf [ 1, 2, 3 ].

Does gypsum mining cause damage evolution?

With the underground space formed by gypsum mining as the object and the construction of oil storage in the gypsum mine goaf as the core goal, the mechanical behavior and damage evolution mechanism of the oil-immersed gypsum ore rock mass were studied at the macro-scale.

Does gypsum rock permeability change after oil immersion?

In general, the structure of gypsum rock is compact, and the permeability of oil in gypsum rock is poor. Thus, the density of the samples after oil immersion changed little compared with that before oil immersion, regardless of whether they were immersed in oil for 15 or 30 days.

How gypsum is mined in China?

China is rich in gypsum ore resources, and the total proved reserves of various types of gypsum rank first in the world. The mining of gypsum mines is mostly carried out using the open field method, so a large number of goaves are inevitably formed after mining is completed.
