摘要
霍州矿区下组煤炭资源储量占总储量的53%以上,但由于下组煤层底板标高普遍低于其下部奥陶系石灰岩岩溶裂隙含水层水位,加之矿区内构造发育,水文地质条件复杂,对下组煤的开采构成了威胁。通过对霍州矿区水文地质条件的分析与研究认为,各井田下组煤开采受岩溶水威胁的程度不尽相同,为保障矿井安全生产,要有针对性实施各井田下煤组的开采方法及防突水措施。
The resources and reserves of lower coal group account for more than 53% in total of Huozhou mining area. But because of the floor elevation of the lower coal group is generally lower than the Ordovician limestone karstic water table, together with complicated structural and hydrogeological conditions in the mining area make up of threatening to the mining of lower group coal. Through analyses and studies of hydrogeological conditions in Huozhou mining area, the author considered that the threatening extent of karstic water to lower coal group is different to particular minefield. To ensure safety mining need to take pertinent mining methods and water irruption control measures to particular minefield.
