| 摘 要： | 天祝县华龙沟区煤炭勘查的主要任务是探明煤层在垂直与水平方向上的变化规律。为此，在其前期预查时采用了多种电法手段．其中以对称剖面法和激电测深方法确定煤层露头具体位置；以五极纵轴测深法和激电测深确定煤层埋深及厚度；以高密度电法确定煤层走向。根据电法成果，结合1：5000地质填图对测区构造及煤层赋存形态进行控制。本次电法勘探成果与地质槽探、硐探对比，其煤炭赋存形态及构造吻合，根据勘查成果估算本区煤炭资源量约5000万t。

| Abstract: | The main task of coal exploration in Hualonggou mine area, Tianzhu County is to find out the varying regularity of coal seams both vertically and horizontally. For this reason, multiple electric means have been used during advanced investigation： in which, use the symmetric profiling and IP sounding to define exact location of coal seam outcrops; five-electrode longitudinal axis sounding and IP sounding to define coal seam buried depth and thickness; high density electric surveying to define coal seam strike extending. According to electric method results, combined with 1：5,000 geological mapping define exploration area structure and coal seam hosting configuration. Contrasting the electric method and trenching and tunneling prospecting, their results on coal seam hosting configuration are quite identical, according to exploration results, estimated coal resources in the area are about 50million tons. |
