摘要
华北型煤田煤层开采广泛受到底板承压水威胁,开展煤层安全开采分区研究对于保障矿井安全生产有着重要的意义。分析影响煤层底板突水的主要因素,利用GIS多元信息复合技术,构建适合潘西煤矿千米深矿井的突水模型,对潘西煤矿主要采区进行危险性评价,形成矿井危险程度分区图,指导潘西煤矿19煤层安全开采。
The mining operation in the seam of North China coalfield was widely suffered with pressurized water dangers from the seam floor.The study on the safety classified blocks of mining seam conducted had an important significance to the mine safety production.The paper analyzed the main factors affected to the water inrush from seam floor.With the GIS multi element information complex technology,a water inrush model suitable for the over 1 000 m depth mine of Panxi Mine was established to have a dangerous asses...
