Embodiment Construction

[0024] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0025] Such as figure 1 Shown is an underground city construction method based on an abandoned mine, including the following steps:

[0026] S1: Combined with the original hydrogeological data of the abandoned mine, arrange ground detection lines on the boundary of the protective coal pillar 16 in the industrial square where the abandoned mine is located, and use the electromagnetic imaging system to investigate and find out the width, height, distribution area and location of the protective coal pillar 16 in the industrial square. Destruction situation, so as to determine the location of gobs, roadways, and complete solid coal in abandoned mines, and use geophysical and chemical prospecting methods to determine the occurrence of mine water and gas in abandoned mines, so as to prepare for the recovery of coal pillars;

[0027] S2: Use the pier pillar fil...

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...
