Abstract

This study analyzed the failure characteristics of the coal seam floor induced by longwall mining to manage and eliminate possible hazards associated with high pressure (8.0 MPa) floor-confined water in the Xinjulong coal mine. The disturbed floor was divided into mining failure (MF), water-resistant (WR), and confined water intrusion (CWI) zones. The MF and CWI zones have lost their ability to resist the confined water, so the WR zone is the key for preventing water inrush from the floor aquifer. A thin-plate model for the WR zone indicated that the water pressure had to be decreased to 2.4 MPa or less. Multi-well pumping was used to decrease the floor aquifer water pressure from 8.0 to 2.1 MPa. Moreover, grouting was used to block water-conducting fractures in the floor strata. In addition, classification, purification, and recycling techniques enabled 84.8% utilization of the produced mine water.

Zusammenfassung

Die vorliegende Studie untersuchte die Charakteristika des durch Strebbau verursachten Versagens des Grundwassernichtleiters unterhalb eines Kohleflözes, um die mit dem unter hohem Druck (8,0 MPa) stehenden, gespannten Grundwasser im Xinjulong Kohlebergwerk einhergehenden potentiellen Gefahren bewältigen und beseitigen zu können. Der beeinträchtige Untergrund wurde in eine Versagenszone (mining failure: MF), eine wasserundurchlässige Zone (water-resistant: WR) und eine Wassereinbruchszone (confined water intrusion: CWI) aufgeteilt. Sowohl WR- als auch CWI-Zone haben ihre wasserstauende Eigenschaft eingebüßt, sodass die WR-Zone der Schlüssel zur Vermeidung von Wassereinbrüchen aus dem darunterliegenden Aquifer ist. Ein Thin-Plate Modell für die WR-Zone ergab, dass der Wasserdruck auf 2,4 MPa oder weniger hätte gesenkt werden müssen. Darüber hinaus wurde eine Verpressung der wasserführenden Klüfte in den Untergrundschichten angewandt. Zusätzlich ermöglichten Methoden zu Einstufung, Aufbereitung und Recycling die Verwendung von 84,8% des im Bergwerk anfallenden Wassers.

Resumen

Este estudio analizó las características de falla del piso de vetas de carbón inducidas por la extracción de muros largos para manejar y eliminar posibles riesgos asociados con el agua confinada en el piso a alta presión (8,0 MPa) en la mina de carbón Xinjulong. El piso perturbado se dividió en zonas de falla minera (MF), resistente al agua (WR) e intrusión de agua confinada (CWI). Las zonas MF y CWI han perdido su capacidad de resistir el agua confinada, por lo que la zona WR es la clave para evitar la irrupción de agua desde el acuífero del piso. Un modelo de placa delgada para la zona WR indicó que la presión del agua tenía que reducirse a 2,4 MPa o menos. El bombeo de pozos múltiples se usó para disminuir la presión del agua del acuífero del piso de 8,0 a 2,1 MPa. Además, la lechada se usó para bloquear las fracturas conductoras de agua en los estratos del piso. Además, las técnicas de clasificación, purificación y reciclaje permitieron la utilización del 84,8% del agua de mina producida.

大采深煤矿底板高压含水层水的管理与利用

为了治理和消除新巨龙煤矿底板含水层高压 (8.0 MPa) 威胁,分析了长壁开采引起的煤层底板破坏特征。受采矿扰动破坏的煤层底板被分为开采破坏带(MF)、阻水带 (WR) 和承压水导升带(CWI)。开采破坏带(MF)和承压导升带(CWI)已经失去阻隔承压水的能力,阻水带(WR)是防止底板含水层突水的关键。阻水带(WR)的薄板模型表明,底板含水层水压需被降至2.4 MPa以下。通过群孔抽水将含水层水压由8.0 MPa降至2.1 MPa;利用注浆技术封堵底板内导水裂隙。此外,矿井水分类、净化和再利用技术使矿井水利用率达84.8%
