摘要:孟村煤矿工作面开采面临着较为严重的顶板水害威胁,在回采前采取有效技术手段探明顶板上方可能存在的垂向导水通道,为顶板疏放水工作提供靶区显得尤为重要,在401103-工作面采用了槽波勘探和顶板高密度电法探测,结果表明:裂隙构造发育区其槽波特征是能量吸收衰减较快,视电阻率值较低,裂隙/断裂构造是工作面顶板含水层的导水通道。该研究成果为矿井治理水害提供了参考资料,也说明了综合物探方法是提前探测工作面内部导含水构造的有效技术手段。
Abstract:Mengcun mining faces a serious threat of roof water damage. When it is guided by water conducting cracks, it can pose asignificant water damage threat to the mine. Therefore, it is paticularly impotant to use effective techmnical means to explore the p.ossibilityof vertical water channels above the rof in the mining area before mining, providing a target area for rof drainage work. Through the use ofslot wave exploration and high-density eletrical detection of the noof in the 401103 working face, the resulas show that the slot wavecharacteristics of the fracture structure development area are fast energy absorption and attenuation, low apparent resistivity valures, and thefracture/fracture structure is the water channel of the roof aquifer in the working face. This provides precise reference materials for the earlymanagement of the mining area， and also demonstrates that comprehensive geophysical methods are effective technical means for earlydetection of water bearing structures within the working face.
