Construction method for underground city based on abandoned mine

Abstract

The invention discloses a construction method for an underground city based on an abandoned mine. The construction method comprises the steps that a pier stud filling method is adopted to recycle industrial square protective coal pillars to form a construction space of the underground city; treatments of skin rolling and beautifying, anchoring and shotcreting and pier-stud-filling reinforced supporting are connected on main roadways and surrounding chambers, and then decoration construction is conducted on the main roadways and the surrounding chambers to form underground business streets; and return-air-shaft protective coal pillars at two sides are recycled through the pier stud filling method to form a regular building space, therefore, the 'one-core, double-city, double-axis and multi-area' construction layout and a main body frame of the underground city are formed, moreover, the whole underground city is equipped with systems of electrical power, ventilation, garbage collection, domestic water, air conditioner, communication, traffic, fire protection and the like, and then self-sufficiency of water, electricity, air and heat of the underground city is achieved. According to the construction method for the underground city based on the abandoned mine, the characters of the abandoned mine are utilized to develop the underground building space, the purposes of enhancing the use ratio of land resources, protecting the environment, relieving the ground traffic pressure and the like are achieved, and optimization of mine resource utilization is achieved.

Description

technical field [0001] The invention relates to an underground city construction method based on an abandoned mine, belonging to the field of underground space development and utilization. Background technique [0002] During the development of coal mines, metallurgical mines, non-ferrous metal mines, chemical mines, and non-metallic deposits, a large number of underground goafs have been formed. Coal mines alone form hundreds of millions of cubic meters of space every year. How to rationally utilize abandoned mines is imminent; Academician Xie Heping pointed out that in the process of eliminating backward coal production capacity and dissolving production capacity, many mines were closed, and depleted coal mines faced various resource, environmental and social problems after they were abandoned or closed. Mining areas often have a large number of ground and underground natural resources, technical resources and human resources. After the traditional model is withdrawn, larg...

AI Technical Summary

Problems solved by technology

Mining areas often have a large number of ground and underground natural resources, technical resources and human resources. After the traditional model is withdrawn, large-scale industrial squares on the ground and a large number of underground equipment and facilities are left idle, resulting in waste of land resources and the inability to resettle personnel.
