摘要:
为实现陕西神木地区哈拉沟煤矿周边小煤矿采空区的精确定位,采用地空时间域电磁系统在哈拉沟煤矿三盘区附近原小煤矿可能开采范围开展勘查工作。利用电源车集成的大功率地面发射系统,搭配基于旋翼无人机的单分量地空电磁信号接收系统,共采集23条测线的电磁数据。经数据处理后,得到勘查区内地下视电阻率与视深度的高分辨率成像剖面,结合已知钻孔资料综合分析,推测勘查区对应地下煤层位置的低阻带是由煤层积水采空区造成,据此共圈定了8处疑似积水采空区,其中5处为相对低阻异常区域,分布于勘查区中南部、中部以及东北部区域。本次探测工作验证了地空时间域电磁系统在煤矿采空区勘查中的有效性,能够为工作面合理布置和采空区治理等提供可靠的地质信息。
Abstract:
In order to realize the precise positioning of goaf in Halagou coal mine of Shenmu area, Shaanxi, the ground-airborne time domain electromagnetic system was used to carry out the geophysical exploration in the original small coal mine near Sanpan district of Halagou coal mine. The high-power ground transmitting system integrated with the power vehicle and the single-component ground-airborne electromagnetic signal receiving system based on rotary-wing unmanned aerial vehicle were used to collect the electromagnetic data of 23 lines. Through data processing, high-resolution imaging profile of underground apparent resistivity and depth in the exploration area was obtained. Combining the imaging results with the analysis of the previously known geological borehole data, it is speculated that the low-resistance zone in the exploration area near the underground coal seam is caused by water-goaf of coal seam. Eight suspected underground water-goafs are delineated, five of them are relatively low-resistance abnormal and distribute in the south-central, central and northeastern of the exploration area. The results of the detection verify the effectiveness of ground-airborne time domain electromagnetic system in the application of goaf exploration, and provide scientific and effective information for geological analysis, groundwater tracking and coal mine exploration engineering.
