在钻探过程中,由于地质或钻探技术方面的原因,常会产生钻孔弯曲。为了保证地质资料的可靠性,必须对孔斜进行校正,计算出见煤点、构造点的三度空间位置。将钻孔中心轴线的实际位置投影到所在或附近的勘探线剖面图上,以获得各点在剖面图上的准确位置,从而绘制出比较符合实际的勘探线剖面图,作为绘制煤层底板等高线图及储量计算图的基础图件。因此,如何选择正确的投影方法,使其效果尽量符合地质体的客观状况,
Drilling is often caused by drilling or drilling due to geological or drilling techniques. In order to ensure the reliability of geological data, it is necessary to calibrate the hole inclination and calculate the three-dimensional position of the coal point and the structural point. The actual position of the center axis of the borehole is projected onto the profile of the prospecting line at or near the site to obtain the accurate location of each spot on the profile map so as to draw a more realistic profile of the prospecting line, The basic diagram of the diagram and reserves calculation chart. Therefore, how to choose the correct projection method to make its effect as close as possible to the objective conditions of the geological body,
