Abstract

A variable-volume, head-dependent mine water filling model (MIFIM) has been utilized to simulate the post-abandonment flooding of the Siersza coal mine in the Upper Silesian Coal Basin of southern Poland. It is demonstrated that desaturated pore space in the aquifer adjacent to the mine comprises a significant component of the resaturable mine-related void. The model results are very sensitive to the value of this poorly constrained parameter. Nevertheless, the model successfully predicted the first appearance of mine water in an observation well and its subsequent rise. Despite this apparent success, it is concluded that such modeling approaches generally lack predictive power for mines in permeable, porous host rocks. As real monitoring data accumulate, however, such models can be calibrated and their utility increased.

Modélisation et suivi de la remontée de l’eau de mine dans un complexe abandonné de mine de charbon: Mine de Siersza, Bassin houiller Haute Silésie, Pologne

Résumé

Un modèle de remplissage de mine à volume variable et dépendant de la charge hydraulique (MIFIM) a été utilisé pour simuler l’inondation de la mine de charbon de Siersza après son abandon, dans le Bassin houiller Haute Silésie en Pologne méridionale. Il est démontré que l’espace interstitiel désaturé de l’aquifère adjacent à la mine comprend une part significative de vides resaturables liés à la mine. Les résultats du modèle sont très sensibles à la valeur de ce paramètre peu contraint. Le modèle a quand même prédit avec succès la première apparition d’eau de mine dans un puits et la montée du niveau qui a suivi. Malgré ce succès apparent, il est conclu qu’une telle approche par modèle manque de capacité prédictive pour des mines dans des roches hôtes perméables et poreuses. Au fur et à mesure de l’accumulation de données de suivi, de tels modèles peuvent cependant être calés et leur utilité croitre.

Modelado y monitoreo del agua de recuperación de una mina en un complejo de minas de carbón abandonadas: Siersza Mine, Upper Silesian Coal Basin, Polonia

Resumen

Se ha utilizado un modelo de llenado de agua de una mina, de volumen variable y dependiente de la carga para simular una inundación post-abandono de una mina de carbón en la cuenca de carbón del Silesian superior en el sur de Polonia. Se demuestra que el espacio poral desaturado en el acuífero adyacente a la mina comprende una componente significativa del vacío resaturable relativo a la mina. Los resultados del modelo son muy sensitivos al valor de este parámetro pobremente vinculado. No obstante el modelo predice exitosamente la primera aparición del agua de la mina en un pozo de observación y su elevación subsecuente. A pesar de este éxito aparente, se concluye que tal enfoque de modelado aproxima por lo general la falta de poder predictivo para minas en rocas reservorios porosas permeables. A medida que los datos de monitoreo se acumulan, sin embargo, tales modelos pueden ser calibrado e incrementar su utilidad.

废弃煤矿中矿坑充水的模拟与监测--以波兰Upper Silesian煤盆Siersza煤矿为例

摘要

应用一个变体积、依赖于水头的矿坑充水模型 (MIFIM) 模拟了波兰南部Upper Silesian煤盆Siersza煤矿废弃后的充水问题。 结果表明, 煤矿附近含水层疏干的孔隙空间是采煤造成的可重新充水空间的重要组成部分。模型试验结果对这一约束不充分的参数值非常敏感。尽管如此, 模型成功预报了矿坑水在一眼观测井中的首次出现及其随后的上涨过程。虽然这次结果很好, 我们认为, 对透水的、多孔围岩中的矿井来说, 这种模拟方法通常预报能力不足。但是, 随着实际监测数据的积聚, 模拟可以进行校正, 实用性也会增强。

Modelação e monitorização da recuperação de níveis da água de mina num complexo mineiro a céu aberto: Mina de Siersza, Bacia Carbonífera da Alta Silésia, Polónia

Resumo

Tem sido utilizado um modelo de enchimento de água de volume variável com dependência da carga hidráulica (MIFIM) para simular a inundação pós-abandono da mina de carvão de Siersza, situada na Bacia Carbonífera da Alta Silésia, no sul da Polónia. Demonstrou-se que o espaço poroso não saturado no aquífero adjacente à mina comporta uma significativa componente ressaturável do vazio relacionado com a mina. Os resultados da modelação são muito sensíveis ao valor deste parâmetro mal definido. No entanto, o modelo previu com sucesso o primeiro aparecimento da água de mina num furo de observação e a sua subsequente ascensão. Apesar deste aparente sucesso, conclui-se que tais abordagens por modelação têm falta de poder preditivo em minas instaladas em rochas porosas e permeáveis. Não obstante, à medida a que se acumulam dados de monitorização, tais modelos podem ser calibrados e incrementada a sua utilidade.
