废弃矿井抽水蓄能句法视角下拓扑模型构建及空间优化

Topological model construction and space optimization of abandoned mine pumped storage from the perspective of space syntax

  • 摘要: 废弃矿井抽水蓄能电站技术不仅是废弃矿井转型升级的重要途径,也是可再生能源规模储能的有效手段。废弃矿井巷道是抽水蓄能电站地下水库理想载体,但其复杂的空间拓扑结构制约了水体的流动性,因此需研究巷道地下空间结构优化方法,为抽水蓄能电站地下水库建设提供技术支撑。以我国淮南某矿东区为研究对象,阐述了空间句法视角下废弃矿井地下空间结构分析方法,建立小尺度多元凸空间的地下空间拓扑模型。借鉴空间句法中各形态分析变量,基于局部与整体层次特征研究巷道和硐室结构之间的内在逻辑性和拓扑关系,分析了废弃矿井地下空间在抽水蓄能电站地下水库建设中存在的问题,并对地下空间结构进行优化。研究表明:基于局部空间特征的地下空间单元可利用性与连接值、控制值、选择度、局部整合度成正比,与平均深度值成反比;基于整体空间特征的地下空间结构全局整合度、可理解度和空间智能度较低,反映在抽水蓄能电站地下水库建设中存在空间导向性差、空间利用率低和蓄能能力弱等问题。因此通过选取局部整合度与全局整合度均高于其平均值的空间单元重新构建新的地下空间拓扑模型,优化后地下空间单元数量减少73%,空间可理解度从很差(0.217)提升到一般(0.480),空间智能度从较高(0.798)提升到极高(0.940),提高了废弃矿井抽水蓄能地下空间结构的通达性与蓄能能力,为废弃矿井抽水蓄能电站建设中地下空间规划与利用提供优化策略。

     

    Abstract: The technology of pumped storage power stations in abandoned mines is not only an important way for the transformation and upgrading of abandoned mines, but also an effective means of renewable energy scaled storage.The roadway of an abandoned mine is an ideal carrier for an underground reservoir pumped storage power station, but its complicated spatial topology restricts the fluidity of the water.Therefore, it is necessary to study the optimization method of the underground spatial structure of the roadway to provide technical support for the construction of the underground reservoir of the pumped storage power station.Taking the eastern area of a mine in Huainan, China as the research object, the analysis method of underground space structure of abandoned mines under the perspective of spatial syntax is expounded, and the underground space topology model of small-scale multivariate convex space is established.Drawing on the various morphological analysis variables in spatial syntax, the internal logicality and topological relationship between the roadways and chamber structures are studied from the local and overall hierarchical characteristics.The problems existing in the underground space of abandoned mines in the construction of underground reservoirs of pumped storage power stations are analyzed, and the underground space structure is optimized.The research shows that the availability of underground space units based on local spatial characteristics is positively proportional to the connection value, control value, selection degree, and local integration degree, and inversely proportional to the average depth value.The global integration, comprehensibility, and spatial intelligence of the underground space structure based on the overall spatial characteristics are low, resulting in some problems such as poor spatial orientation, low spatial utilization, and weak storage capacity in the construction of underground reservoirs of pumped storage power stations.Therefore, a new topological model of underground space is reconstructed by selecting spatial units with local integration degree and global integration degree higher than their average.After optimization, the number of underground space units is reduced by 73%, the spatial intelligibility is improved from very poor(0.217)to general(0.480), and the spatial intelligence is improved from high(0.798)to extremely high(0.940).It improves the accessibility and storage capacity of the underground space structure of abandoned mine pumped storage power station, and provides an optimization strategy for the planning and utilization of underground space in the construction of pumped storage power stations in abandoned mines.
