摘要
为了论证地巷联合瞬变电磁法探测煤矿井下采空区积水的有效性,用水和薄铜板分别模拟均匀半空间和采空区积水,研究水平分量的异常响应。结果显示,X、Y分量对采空区反映明显,其中,X分量过零点与Y分量极值点均对应采空区中心位置。X、Y分量曲线组合形态与采空区空间方位密切相关。模拟结果证明,地巷联合瞬变电磁法能准确发现采空区积水,并有望确定其空间方位。
In order to demonstrate the effectiveness of the combined transient electromagnetic method to detect the water accumulated in the coal mine underground, the water and thin copper plates were used to simulate the uniform half space and the water in the goal respectively, and the abnormal response of the horizontal component was studied. The results showed that the X and Y components are obvious to the goal, and the X component zero crossing and the Y component extreme point correspond to the center of the gob. The combination of X and Y component curves is closely related to the spatial orientation of the goal. The simulation results showed that the combined ground and transient transient electromagnetic method can accurately find the water in the goal and is expected to determine its spatial orientation.
