在煤层露头良好的地区,确定煤层露头在地形图上的位置,是一件容易的事。但是在地形切割较深,高差较大,浮土掩盖,植被较密的情况下(如十万大山)则较难。如果凭少数地质点用“V”字法则推测煤层露头线位置,往往误差较大。要准确地确定煤层露头位置,不得不使用大量的山地工程。根据我们在野外地质工作的实践,应用数学法确定岩、煤层露头简便易行,精度较高。在构造简单、岩层产状较稳定的地区普查找煤,用数学法确定煤层露头位置和地质界线,不但可以节省很多野外工作量和山地工程量,而且能提高地质图的精度。但是,使用
In areas with good coal outcrops, it is an easy task to determine the location of coal outcrops on topographic maps. However, it is more difficult to cut deep terrain, large height difference, cover up with floating soil and dense vegetation (such as Shiwandashan Mountain). If by virtue of a small number of geological points with the “V” rule presumption of outcrop coal seam location, often larger error. To accurately determine the coal outcrop location, had to use a large number of mountain projects. According to our practice in the field of geological work, the use of mathematical methods to determine rock, coal outcrops simple and easy, with higher accuracy. In the area of simple structure and relatively stable rock formation, coal prospecting is generally carried out. Using mathematical methods to determine the coal outcrop location and geological boundary, not only can save a lot of field workload and mountain engineering quantity, but also can improve the accuracy of geological map. However, use
