【摘要】 内蒙古新上海庙地区是煤田地质勘探的空白区,其地表为干旱、半干旱沙漠及黄土覆盖,属地震条件复杂地区。本次勘探在“三边”工作基础上,优化地震工程设计,共布设地震测线16条。经充分实验,确定了激发参数及接收参数。根据勘探区地震地质条件横向变化大的特点,在处理中始终以三高为中心。以静校正、反褶积为重点,选择最佳处理流程及参数,基本控制了区内主要可采煤层赋存情况,并否定了原断距1700m的区域大断层一沙葱沟断层。更多还原

【Abstract】 Xinshanghaimiao area of Inner Mongolia is an area without any coal geological exploration activities before.The surface is an arid,semiarid desert and loess covering area,seismic prospecting condition is complex.Prospecting this time is based on the“analyzing the in being data,rectifying prospecting design,while the prospecting is progressing”principle to optimize seismic engineering design,spread total 16 prospecting lines.After made sufficient testing,determined shot and receiving parameters.By virtue of major transverse changes of seismic-geologic condition,we took“three highs”(high resolution,high signal-to-noise ratio and high fidelity)as the hub and put stress on statics and deconvohtion during data processing,selected optimum processing flow and parameters.After prospecting,basically controlled main mineable coal seam occurrences;found 251km2 coal-bearing area above 1200m depth;denied originally presumed regional major fault with 1700m displacement-the Shaconggou fault.After drilling validating,total 12.448 billion tons of coal resources in the area have estimated.更多还原
