ABSTRACT
Underground buildings compared with ordinary concrete buildings are particular. Especially for some deep shaft buildings, the concrete needs to withstand greater pressure. The mine shafts as auxiliary facilities provide the channel for exploitation and transportation, besides, with some special buildings, the efficiency of mining can be improved. In actual process, the underground concrete buildings should vary according to different resources. For instance, in the mining of coal resources, the safety measures like fire prevention must be taken into account. As for mining of rare minerals, the mining efficiency must be paid more attention [2]. The deeper the resources are stored the greater load should the building bear, thus the correspondingly thicker concrete. China is vast in territory and rich in resources. There are large numbers of mine facilities. Adjustment should be made according to different geological and geographical conditions. In the process of the excavation of the mine shafts, if the favorable geological and geographical conditions could be made use of, it can largely improve the efficiency of construction, such as the use of layer with larger bearing
1 INTRODUCTION
The level of industry is an important symbol of a country’s comprehensive strength. Therefore, the importance of industrial development is obvious. The energy resources such as coal and oil etc., as the basis for industry guarantee the development of industries. The production status of energy resources can directly affect the industrial level. In addition, many rare metal mineral resources also play an important role in industrial development. Yet mining of coal and rare metal minerals usually require mine shafts. In the past, there was not enough understanding of mine construction to a certain extent, affecting mining efficiency in actual production. In the early times, due to lack of funding, foreign companies and investment were attracted, in hope of promoting China’s economic development with foreign funds and the rich mineral resources were the main driving force for foreign companies to come into China [1]. Until now, the exploitation of resources through the mine shafts remains the main driving force of economic growth, but by the survey it’s found that companies attach more importance to productivity and economic benefits than to the construction of mines, which didn’t only influence mining efficiency, but also resulted in some safety incidents.
