干河井田断层突水机理研究

Study on Mechanism of Water Inrush from Fault in Ganhe Mine Field

在开采干河井田2号煤层过程中曾多次发生断层突水事故,对矿井安全生产造成极大影响。通过对井田断层发育规律、主要含水层赋水特征及断层突水机理进行分析研究,总结出干河井田断层突水的规律,对今后煤层开采时防止断层突水具有现实指导意义。

Several water inrush accidents from faults occurred in the mining process of No. 2 coal seam in Ganhe Mine Field, which caused serious influence on the safe production of the mine. Based on the analysis and study of the development regularity of faults, water enrichment characteristics of the major aquifers and water inrush mechanism from faults in the mine field, this paper summarized the regularity of water inrush from faults in Ganhe Mine Field, which has practical guiding significance for preventing water inrush from fault in coal mining.
