大汶口石膏矿区石膏矿房地下空间特征和利用对策探析

Analysis on Underground Space Characteristics and Utilization Countermeasures of Gypsum Mine House in Dawenkou Gypsum Mine Area

大汶口矿区石膏矿产资源丰富,经过近30年的开发利用,形成了一定数量规模、结构相对稳定的石膏矿房地下空间。该文通过对大汶口矿区现有石膏矿床特征和开采技术条件分析,在调查了解矿山开发利用现状基础上,研究总结了石膏矿房地下空间特征,认为其埋藏深度适中,呈层状分布,矿房空间结构稳定且密闭性好,空间规模潜力大并易于监控;并就影响开发利用因素进行了分析,围绕石膏矿房地下空间开发利用提出对策,石膏矿房地下空间开发利用有利于促进石膏矿山开发转型升级,实现矿业持续、绿色发展。同时,在石膏地下空间利用的思路下,拓展了煤炭、岩盐等其他矿产地下采矿空间开发建议。

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.
