| 摘 要： | 从突水水源、导水通道、压力条件、采掘条件等方面分析了曹窑东井27080工作面非断层条件下煤层底板大型奥灰突水原因.分析表明:地下水径流条带的存在和底板有效隔水层厚度不足是导致奥灰突水的根本原因.奥陶系岩溶裂隙水是此次突水的水源;高水压为突水提供了动力条件;煤层底板薄弱区在水压与矿压的联合作用下经"撕裂"形成了导水通道;采掘活动是本次突水的诱发因素,也为突水提供了空间.指出随着采深增加,奥灰水压升高,突水危险性增加.提出了避免再次奥灰突水,做好物探查异、钻探查证和突水危险区注浆加固改造等方面的建议措施.

| Abstract: | From the water inrush source,water conductive channel,pressure conditions,mining and excavation conditions,the paper an- alyzed the cause of the large Ordovician Karst water inrush from the seam floor in 27080 coal mining face of Caoyao East Mine without a fault condition.The analysis showed that the existing underground water flowing channel and zone and the effective thickness of the water isolation layer not thick enough were the fundamental causes to occur the Ordovician Karst water inrush.The water in ... |
