悦昌煤业开采的1#、2#煤层为近距离煤层,地质及水文地质条件复杂。为超前探明1-101首采工作面地质构造及小窑破坏区范围,采用了矿井瞬变电磁法、探地雷达、音频电透视法等综合物探技术对1-101首采工作面进行地质探查,查明了工作面隐伏导水构造及小窑采空破坏区范围,为工作面的防治水工作提供了充足的地质依据。
The No. 1 and No. 2 coal seam mined in Yuechang Coal Mining is a short distance coal seam with complicated geological and hydrogeological conditions. In order to find out the scope of 1-101 first coal mining face and the area of small kiln destruction area in advance, comprehensive geophysical techniques such as mine transient electromagnetic method, ground penetrating radar and audio-electric electro- Exploration, to identify the hidden surface of the water conduction structure and the scope of the small kiln mined-out area for the work of prevention and control of water to provide a sufficient geological basis.
