摘要
以辛置矿实际生产条件为背景,对该矿下组煤开采可能存在的地下水隐患类型及其特征进行了分析,对下组煤底板奥灰带压开采进行了危险性分区。结果表明,该矿地下水隐患可以分为3类:顶板水、老空积水和底板奥灰承压水。底板奥灰带压开采可分为较安全区、中等危险区、危险区,并在此基础上,提出了防治对策确保煤矿安全高效生产。
Based on the actual production conditions of XinZhi Mine,the types and characteristics of underground water hazards that may exist in the mining of the lower coalseams are analyzed.The results show that the hidden dangers of underground water in the mine can be divided into three categories:water above roof,water in goaf and water under floor.Ordovician water under the floor can be divided into safer zone,medium danger zone and danger zone.The prevention and control measures are put forward to ensure the safe and efficient production based on the above analysis.
