Abstract

Mining activities and geological conditions affect underground aquifers and surface water by different mechanisms. In this paper, we report three cases that illustrate some key factors and mechanisms to protect water supply during underground mining. Underground aquifers or surface water may be protected by controlling key strata movement, insuring an appropriate interburden thickness, and protecting the immediate aquiclude.

Mechanismen der Aquifer Schutz in untertägigen Steinkohlenbergbau

Zusammenfassung

Bergbauaktivitäten und geologischen Bedingungen beeinflussen unterirdischen Grundwasserleiter und Oberflächenwasser durch verschiedene Mechanismen. In diesem Beitrag berichten wir drei Fälle, die einige der wichtigsten Faktoren und Mechanismen, um die Wasserversorgung im Untertage-Bergbau zu schützen, zu veranschaulichen. U-Bahn-Grundwasserleiter und Oberflächenwasser kann durch Steuern Schlüssel Schichten Bewegung, die Versicherung eine entsprechende interburden Dicke und den Schutz der unmittelbaren aquiclude geschützt werden.

Mecanismos de Protección de Acuíferos en metro la Minería del Carbón

Resumen

Las actividades mineras y las condiciones geológicas afectan a los acuíferos subterráneos y aguas superficiales por diferentes mecanismos. En este trabajo, reportamos tres casos que ilustran algunos de los factores y mecanismos para proteger el suministro de agua durante la minería subterránea clave. Los acuíferos subterráneos o las aguas superficiales pueden ser protegidas mediante el control de movimiento es estratos clave, asegurando un espesor adecuado de material estéril entre mantos y protegiendo el acuicludo cercano.

地下煤炭开采中的含水层保护机理

摘要

不同开采活动和地质条件对地下含水层和地表水体的影响机理是不同的。本文通过三个案例阐述了地下保水开采一些主要影响因素和机理。通过控制关键层移动特征、形成合理的中间层厚度以及保护直接隔水层等,可以实现对地下含水层和地表水体的保护。
