【摘要】：由于不同矿区地质复杂程度、采矿条件的差异性,从而决定了底板突水主控因素的不同。以蔚州矿区及单侯矿井地质采矿条件为背景,在研究蔚州矿区突水时空特征的前提下,重点分析矿区突水资料与岩溶含水层的分布规律、富水特性的空间位置关系,定性确定蔚州矿区突水的主控因素。并以单侯矿井为例,采用多源信息融合技术定量评价单侯矿井突水主控因素。研究结果表明:蔚州矿区突水的主控因素为岩溶发育程度、隔水层厚度及其岩性组合、含水层的水压及富水性、断层的规模。而对于单侯矿井,在底板突水众多影响因素中,地质构造占主导因素,其次为隔水层厚度、含水层水压和含水层富水性。
[Abstract]:Because of the geological complexity of different mining areas and the difference of mining conditions, the main controlling factors of water inrush of floor plate are different. Based on the geological and mining conditions of Weizhou and Danhou mines, the spatial and temporal characteristics of water inrush in Weizhou mining area are studied, and the distribution law of water inrush data and karst aquifer, and the spatial location relationship of water-rich characteristics are analyzed emphatically. The main controlling factors of water inrush in Weizhou mining area were determined qualitatively. Taking Danhou mine as an example, the multi-source information fusion technique is used to quantitatively evaluate the main control factors of water inrush in Danhou mine. The results show that the main controlling factors of water inrush in Weizhou mining area are the degree of karst development, the thickness of water barrier layer and its lithology combination, the water pressure and water enrichment of aquifer, and the scale of fault. For Danhou mine, geological structure is the dominant factor among the many influencing factors of floor water inrush, followed by the thickness of water-barrier layer, aquifer water pressure and water-rich aquifer.
