山西高河井田属海河水系长治盆地水文区,主要河流为纵贯全区的浊漳河,自西南流入区内。勘探区内地形地质条件复杂,河流及河漫滩面积大,为克服三维地震勘探存在的诸如检波线的铺设、检波器藕合、激发层位选择等难题,主要采取了陆上检波器挖坑埋置(黄土地段坑深20cm,沙滩地段坑深40cm)、水上检波器用木桩固定等措施,并采用陆上井中放炮、砾石层坑炮、河水中水下放炮相结合的激发方式。为防止井喷和声波产生的高频随机干扰,采取浅井井口压沙袋技术。通过处理解释,获得了较为精确的断层、陷落柱等地质信息,为矿方安全生产提供了可靠的地质保障。
Shanxi Gaohe Minefield belongs to the Haihe River water system Changzhi Basin Hydrologic Area. The main rivers are Zhuozhanghe River that runs through the whole area and flows into the area from the southwest. In order to overcome the problems such as the laying of geophones, the coupling of geophones and the choice of excitation horizon, the terrain and geological conditions in the exploration area are complex and the area of rivers and floodplains is large. (Loess pit depth of 20cm, beach depth of 40cm pit), water detector fixed with wooden piles and other measures, and the use of land wells blasting, gravel pit guns, underwater fire in the water combined excitation mode. In order to prevent blowout and sound waves generated by random high-frequency interference, shallow wellhead sandbags to take pressure technology. Through the processing and interpretation, more accurate geological information such as faults and collapsing columns was obtained, which provided reliable geological guarantee for mine safety production.
