摘要
针对玉山井田101煤层距离奥灰岩溶裂隙含水层距离较近,存在底板突水威胁的现状,在收集地质钻孔资料基础上,编制了101煤层底板至奥灰顶板间距等值线图、101煤层底板奥灰水压等值线图、101煤层底板奥灰突水系数等值线图、101煤层底板奥灰突水危险性分区图,计算了受奥灰突水威胁的101煤层安全开采标高,得出了玉山煤矿开采101煤层发生奥灰含水层底板突水危险性很大的结论。
In view of the current situation that the 101 coal seam in Yushan mine field is relatively close to the Ordovician limestone karst fissure aquifer, there is a threat of water inrush from the floor.Based on the geological drilling date collection, compiled the contour map of the distance between the 101 coal seam and Ordovician limestone, the contour map of Ordovician limestone hydraulic pressure of 101 coal seam floor, the contour map of Ordovician limestone water inrush coefficient of 101 coal seam floor and zoning map of water inrush from the Ordovician limestone aquifer of 101 coal seam floor,calculated the safety mining elevation of 101 coal seam under the threat of water inrush from Ordovician limestone aquifer, and concluded that there is a great risk of Ordovician limestone aquifer water inrush if mining 101 coal seam in Yushan coalmine.
