Abstract:Dawenkou gypsum mining area is rich in gypsum mineral resources. After nearly 30 years of development and utilization, it has formed a certain amount of scale, a relatively stable structure of gypsum mine room underground space. Based on the analysis of the characteristics of the existing gypsum deposits in Dawenkou mining area and the mining technical conditions, on the basis of investigation and understanding of current condition of the development and utilization of the mines, the characteristics of underground space of gypsum mines have been studied and summarized. It is considered that the burial depth is moderate and the distribution is layered. Space structure is stable and airtight, space potential is large and easy to monitor. Then the factors affecting development and utilization, and proposes countermeasures for the development and utilization of underground space in gypsum mines. The development and utilization of underground space in gypsum mines will promote the transformation and upgrade the development of gypsum mines and realize the sustainable and green development of the mining industry. Finally, under the idea of the utilization of gypsum underground space, the space development proposals for underground mining of coal, rock salt and other minerals have been expanded.
