本申请要求于 2013年 4月 7日提交中国专利局、申请号为 2013101 18154.6、 发明名称为 "双巷多电极电透视探测系统" 的中国专利申请的优先权， 其全部 内容通过引用结合在本申请中。 This application claims priority to Chinese Patent Application No. 2013101 18154.6, entitled "Shuangxiang Multi-electrode Electro-optical Detection System", filed on April 7, 2013, the entire contents of which are incorporated herein by reference. In the application.
技术领域 本发明涉及机械技术， 尤其涉及一种双巷多电极电透视探测系统。 背景技术 矿井工作面回采过程中常常受到地下水的威胁。特别是水文地质条件 比较复杂的矿井，时常受到矿井突水的威胁，必须探测地下水的赋存情况， 消除水害。 目前， 矿井工作面水害的探测采用物探和钻探相结合的方法， 通常为先进行物探探査， 再利用钻探进行验证， 确保矿井安全生产。 直流 电法探测矿井工作面富水区可以采用的工作方法有高密度电阻率法和直 流电透视法。 TECHNICAL FIELD The present invention relates to mechanical technology, and more particularly to a dual lane multi-electrode perspective detection system. BACKGROUND OF THE INVENTION Mine face mining surfaces are often threatened by groundwater. In particular, mines with complex hydrogeological conditions are often threatened by mine water inrush. It is necessary to detect the occurrence of groundwater and eliminate water damage. At present, the detection of water damage in the working face of the mine is carried out by a combination of geophysical exploration and drilling, usually by first conducting geophysical exploration and then using drilling to verify the safety of the mine. The working methods that can be used to detect the water-rich area of the mine face by direct current method are high-density resistivity method and direct current electro-optical method.
矿井高密度电阻率法是目前矿井工作面探水较为流行的探测方法。参 见图 1， 该方法沿矿井工作面巷道底板或顶板一次布置多组电极 40 (每组 通常为 60个电极以上） ， 电极间距常为 2〜5m， 探测深度在 100m以内， 每组单独设置电法仪 41， 通过电法仪 41测量得到相邻测量电极间的电位 值。通过该电位值可以反映巷道底板 /顶板附近相对富水区的展布情况。一 站探测结束后， 整体移到下一站测线进行探测。 但该方法由于为一维方向 布置测线， 对工作面内的相对富水区的平面位置难以准确定位。 发明内容 本发明提供一种双巷多电极电透视探测系统， 用于提高相对富水区的 平面位置定位的准确性。 The mine high-density resistivity method is a popular detection method for mine water exploration. Referring to Fig. 1, the method arranges a plurality of sets of electrodes 40 (each group is usually more than 60 electrodes) along the bottom plate or the top plate of the working face of the mine, the electrode spacing is usually 2~5m, the detection depth is within 100m, and each group is separately set with electricity. The meter 41 measures the potential value between adjacent measuring electrodes by the electric meter 41. The potential value can reflect the spread of the relatively rich water area near the floor/top of the roadway. After the end of one station detection, the whole station is moved to the next station line for detection. However, since the method arranges the measurement lines in the one-dimensional direction, it is difficult to accurately position the plane position of the relatively rich water area in the working surface. SUMMARY OF THE INVENTION The present invention provides a dual lane multi-electrode perspective detection system for improving the accuracy of planar positional positioning of relatively rich regions.

The number of the electrode cables 11 is two, and each of the electrode cables 11 is provided with an array electrode, and each group has a plurality of electrodes; the electric instrument 12 is used for measuring each of the corresponding groups on the two electrode cables 11 The potential value between the electrodes; the number of the cable connecting wires 13 is several, and is used for electrically connecting each of the electrode cables 11 to the electric instrument 12 .
巷道的工作面形成之后，可以利用进风巷道、回风巷道以及开切眼（或 联巷） 布置上述双巷多电极电透视探测系统。 参见图 2， 将两根电极电缆 1 1分别布置在进风巷道和回风巷道中， 电法仪 12布置在开切眼中， 采用 电缆连接线 13将各电极电缆 1 1与电法仪 12电性连接。 After the working face of the roadway is formed, the above-mentioned double-lane multi-electrode electro-optical detection system can be arranged by using the air inlet roadway, the return air roadway and the open-cutting eye (or the connecting lane). Referring to FIG. 2, two electrode cables 11 are respectively arranged in the air inlet roadway and the return air roadway, and the electric instrument 12 is arranged in the open cut eye, and each electrode cable 11 and the electric law meter 12 are electrically connected by a cable connecting line 13. Sexual connection.
测量时， 采用电法仪分别测量对应组的两个电极之间的电位值。 进风 巷道中电极电缆上第一组电极与回风巷道中电极电缆上第一组电极对应； 进风巷道中电极电缆上第二组电极与回风巷道中电极电缆上第二组电极 对应； 进风巷道中电极电缆上第三组电极与回风巷道中电极电缆上第三组 电极对应； 以此类推。 During the measurement, the potential value between the two electrodes of the corresponding group was measured by an electric instrument. The first group of electrodes on the electrode cable of the inlet duct corresponds to the first group of electrodes on the electrode cable of the return air passage; the second group of electrodes on the electrode cable of the inlet duct corresponds to the second group of electrodes on the electrode cable of the return duct; The third set of electrodes on the electrode cable in the inlet tunnel corresponds to the third set of electrodes on the electrode cable in the return airway; and so on.
电法仪 12需测量进风巷道中电极电缆 1 1上第一组电极中的每个电极 与回风巷道中电极电缆 1 1上第一组电极中每个电极之间的电位值。 电极 电缆 11上第一组电极中的各个电极分别为 1、 2、 3…… N; 回风巷道中电 极电缆 11上第一组电极中各个电极分别为 N+ l、 N+2、 N+3…… 2No 具体 测量时， 电极电缆 11上第一组电极中的供电电极为 1〜N中的任意一个， 比如为电极 1。回风巷道中电极电缆 11上的供电电极为 N+1〜2N中的任意 一个。 例如当电极电缆 1 1的供电电极为电极 1时， 回风巷道中电极电缆
