Research and Application of Geophysical Prospecting Map Drawing for Irregular Working Faces

摘要

摘要: 为了直观显示不规则工作面综合探测成果,采用无线电波透视与瞬变电磁技术对某矿不规则132155工作面进行综合探测,根据工作面的几何形状进行探测设计,按设计要求进行测点布设和采集数据,建立坐标系,分段进行坐标计算、深度坐标转换与求取射线长度,利用视电阻率和相对衰减系数绘制物探成果图;再与常规处理成果图进行对比分析,最后通过回采情况验证探测成果的准确性。研究表明:不规则工作面成果图绘制方法可以应用于各种形状的工作面;绘制的成果图与工作面形状一致,物探成果更加直观,异常位置与实际揭露情况一致性较好,解释成果相对较为准确。

Abstract: To intuitively display the comprehensive detection results of irregular working face, the radio wave perspective and transient electromagnetic technology are used to detect irregular 132155 working face comprehensively. According to the geometric shape of working face, the detection design is carried out. According to the design requirements, the survey points are laid out and the data collection is carried out. The coordinate system is established. The coordinate calculation, depth coordinate transformation and ray length are carried out in segments. The resistivity and relative attenuation coefficient are used to draw the geophysical exploration result map, and then compared with the conventional processing result map. Finally, the accuracy of the detection result is verified by the mining situation. The research shows that the drawing method of irregular working face result map can be applied to all kinds of working face; the drawing result map is consistent with the shape of working face, the geophysical prospecting result is more intuitive, the abnormal position is consistent with the actual exposure situation, and the interpretation result is relatively accurate.
