摘要
金凤煤矿为保证安全生产,需查明18煤顶板主要含水层空间分布规律及工作面内隐伏断层、小构造等地质异常体。结合井田内地质勘查及矿井开拓资料,运用音频电透视法和"三图-双预测"评价法,分析了工程范围内水文地质条件与充水特征,对含水层富水性及煤层开采时的突水危险性进行了预测;运用无线电波坑道透视法,对工作面内的隐伏地质情况进行了探测,为工作面过断层提供了技术支撑,确保了工作面安全高效开采。
In order to ensure a safety production,Jinfeng Mine was required to investigate a space distribution law of the main aquifer in No.18 seam roof,buried faults,small structures and other geological anomaly in the coal mining face.In combination with the minefield geological exploration and the mine development information,an audio-frequency electrical penetration method and＂three drawing-double prediction＂evaluation method were applied to analyze the hydrogeological conditions and water filling features of the minefield within the engineering scope.A prediction was conducted on the watery of the aquifer and the mine water inrush danger in the seam mining period.A mine roadway radio-wave penetration method was applied to detect the buried geological conditions in the coal mining face in order to provide a technical support to the coal mining face passing through the faults and to ensure a safety and high efficient mining of the coal mining face.
