一、引言为提高煤田的勘探精度,降低勘探成本,增进煤田的开发效益,并配合钻井勘探,推进地震勘探方法在沙漠地区的应用,以解决沙漠煤田中的重要地质问题,我们在内蒙古巴图塔井田,用浅层地震勘探方法查明了沙漠煤层断层 F_1的断距、产状、走向及地表平面位置,并发现了 F_2～F_4隐伏断层;查明了母花海子第四纪掩埋河道和 A 区南、东缘第四 I. INTRODUCTION In order to improve the exploration accuracy of coalfields, reduce the exploration cost, enhance the development benefit of coalfields, and cooperate with the drilling exploration to promote the application of seismic exploration methods in desert areas to solve the important geological problems in desert coalfields, In Tarim field, the fault spacing, occurrence, direction and surface plane position of fault F_1 of desert coal seam were identified by shallow seismic exploration method, and the buried faults of F_2 ~ F_4 were found.
