Evolution of mine caves in soluble rocks driven by deep-seated settings

可溶性岩石的渗透率随时间显著增加。虽然原始渗透率由初始孔隙和裂缝空间控制，但通过可溶性岩石循环的流体可以从孔隙和裂缝表面去除材料，增加岩石中相互连接的空隙空间，从而产生次生渗透率，通常比原始渗透率大几个数量级。当可溶性岩石中的物质转移通过扩大的管道产生集中流动时，我们通常将该系统称为岩溶。裂缝和孔隙的扩大称为洞穴形成。岩溶的时间演化是由水流驱动的。根据流体的来源，我们区分后生和后生岩溶演化，前者与流动从上面的可溶性岩层，后者与流动从下面。虽然后生岩溶演化是很好的理解和主导的文献，后生岩溶演化更难以捉摸。其原因往往是深成环境下发育的岩溶结构的可达性受到限制。我们建议开发的数值模型，耦合流，运输和反应，它描述了一个物种类型的洞穴，矿洞，通过采矿发现，往往在后生条件下开发的时间演变。我们使用各种位置（来自德国）来推导设置和适当的边界条件。重点放在两个不同的方面，在矿洞设置的化学和流动，我们想了解的过程中导致矿洞形成的定量方法。

Permeability in soluble rocks increases significantly with time. While the primary permeability is controlled by the initial pore and fracture space, the fluid circulating through soluble rocks can remove material from pore and fracture surfaces, increasing the interconnected void space in the rock and thus creating a secondary permeability, often orders of magnitude larger than the primary permeability. When the mass transfer in soluble rocks creates focused flow through enlarged conduits, we often refer to the system as karst. The enlargement of fractures and pore spaces is called speleogenesis. The temporal evolution of karst is driven by flow. Depending on the origin of the fluid, we distinguish epigenetic and hypogenetic karst evolution, the former with flow from above the soluble rock formation, the latter with flow from below. While epigenetic karst evolution is well understood and dominates the literature, hypogenetic karst evolution is more elusive. The reason is often the restricted accessibility of karst structures developed under hypogene settings. We propose to develop numerical models, coupling flow, transport and reaction, which describe the temporal evolution of a species type of caves, mine caves, discovered by mining and often developed under hypogenetic conditions. We use a variety of locations (from Germany) to derive a setup and appropriate boundary conditions. Focusing on two different aspects, the chemistry and the flow in mine-cave settings, we want to learn about the processes leading to mine-cave formation in a quantitative way.
