采用精细的正演和拟神经网络反演技术对邯郸矿区北李庄井田的高磁资料进行正演、反演研究和资料分析.针对本地区磁场的特点,用先进的位场正演和分离技术将本区上、下层火成岩的磁场进行了分离.在此基础上对下层火成岩磁场进行三维反演,确定了下层火成岩的底界埋深及厚度,并据此提供了进一步找煤的勘探孔位.在其他物探方法难以取得找煤效果的情况下,该方法保证了高精度磁测工作在本区的有效性.
The forward modeling, inversion analysis and data analysis of the high magnetic field data of North Li Zhuang Minefield in Handan Mining Area are carried out by using sophisticated forward and artificial neural network inversion techniques. Aiming at the characteristics of the local magnetic field, the magnetic fields of the upper and lower igneous rocks are separated by advanced forward field and separation techniques. Based on this, a three-dimensional inversion of the igneous field in the lower igneous rock is carried out. The depth and thickness of the bottom igneous rock are determined, and the exploration holes for further coal prospecting are provided. This method guarantees the validity of high-precision magnetic surveying in this area under the condition that it is difficult for other geophysical methods to obtain the coal-seeking effect.
