为了分析柠条塔矿S1210工作面突水的原因,阐述了周边矿井及柠条塔矿以往采掘中的水害情况,总结了S1210工作面的突水特征,叙述了突水后进行的勘探工作,研究了造成突水的突水通道、突水水源、突水补给条件及突水的差异性。分析认为,本次突水的通道为冒落带及导水裂隙带;直接突水水源为延安组砂岩水及直罗组砂岩水,其中直罗组砂岩水为主要直接充水水源,间接突水水源为第四系松散层水及烧变岩水;突水的补给条件好与地表风积沙地貌入渗系数大有关;研究认为,本次突水与周边矿井差异性较大与突水位置为直罗期古河流冲刷带有关。
In order to analyze the causes of water inrush in S1210 working face of Caitian column, the water damage in the surrounding mines and Caitian taphon mine was expatiated. The water inrush characteristics in S1210 working face were summarized. The exploration work after water inrush was described, The water inrush channel, water inrush source, inrush water supply condition and water inrush caused by water inrush were studied. The analysis shows that the channel of this water inrush is a caving zone and a water-conducting fractured zone; the direct water inrush is sandstone water in Yan’an Formation and sandstone water in Zhiluo Formation, of which sandstone water in Zhiluo Formation is the main direct water-filling source, The water source is the Quaternary loose layer water and the burnt rock water. The good water supply conditions of the water inrush are closely related to the infiltration coefficient of the surface aeolian sand and sandy landform. It is believed that the difference between the water inrush and surrounding mines and the water inrush position For the ancient Luo River wash with the ancient river.
